Im quite curious as well. I really like the minis made my Minicatracing just unsure of getting something so small. Debating either one of those or trying to find a used vac-u-pickle or DF hydro.

I've been looking at that for quite some time. Can't wait to see what you can do with it!

[ride1226]

That looks to be a pretty nice little setup. And im sure with this boat being so small you really save alot on electronics as well. What do you plan to use for a motor mount and whats your power plant gonna be? So far Im thinking of following your footsteps.

[JimClark]

I have one of the struts I would have to measure it but there is not a lot of adjustment available. It is like .187 to .25 max


Please LMK if that strut has any Vert adj

[Meniscus]

After recent testing at the pond in some of the smaller stuff, I recommend trying a 380L ;) Yes it's overkill, but on my Oberto and with Diego's Warrior, it's ridiculous! And lots of fun too!

I ordered this mount and plan on running a 380l with a hextronix 120 or one of those 60amp seaking esc's on 3s

[JimClark]

I think there ia a little more you could open up the hole but it seemed ok as long as you could mount the bracket near the bottom which is easy in most boats. It would also be easy to make a different bracket to lower it even further if needed.

Oops, use the link again, I fixed it. In the 380 only size, there's one in stock. Sorry for the confusion.

[Meniscus]

OK, somehow the link doesn't work. Go to motor mounts, then one down from the 380/540 size, you'll find the 380 only size. There's also the ETTI version at the bottom of the page for 380 size.

[ride1226]

Would be a pretty neat build. I have never built from bare hull before so im scared to death about running the shaft through the hull and how to place everything. And for the price it seems its cheaper to just go with one of the minicatracing hydros, or even one of the ebay hydros. Just dunno which would come out most cost effective and perform the best. Might just keep my eyes open for a used bigger hydro with a sv setup in it. Thats plenty fast enough and fun for my sport running.

[egneg]

This is my shovel nose and it was my first build. Not quite a micro but all builds are basically the same.

Great info, what speeds are you seeing? And what props have you run?

[ride1226]

Im really looking into the little minicat hydro. I like the fact I can run it in smaller pond areas that dont get hit with as much wind.

Is it possible to add a turn fin to both sides and maybe have it able to turn equally as well in both directions for sport running?

Im really trying to get my skunkworks cat finished so I can decide if I wanna sell the cat or the titan 29 that I have to just keep one for sport running then maybe build a larger hydro. God if only I was rich I would just keep and run every boat I want haha.

[HOTWATER]

I would like to have one of the Minicatracing Hydros to run while I wait for my Renegade Rigger to cool down between runs. Also like the fact that it is about the same size as my rigger!!:thumbup1:

Anybody else having any luck running these?

I had a mini cat racing micro hydro and it was fantastic! fast and stable ride, I loved that thing!

Hey Rumdog, What size lipos did you run in it? Did anything ever overheat >ESC, Motor or lipos?

[Rumdog]

I ran a 3s 25c 2000mah rhino lipo. no heat issues at all, the water pickup worked very well. I did upgrade it to a feigao 380 8l and it was ballistic! totally overkill and unnecessary though, but fun!

[wamf]

I'm running a megatech h2o 9" hull with a 3000kv tiny outrunner a 30 amp mystery esc and a 1300 2c lipo. Octura 27mm prop cut down to 22mm, semi surface drive. No cooling and it gets warm not hot, runs for about 15min goes about 15mph and is self righting. It needs to be pretty calm water to run it but it is very fun.

I have a 22" tub rigger that has a 7S-5070kv can that I once fed with 3S to the 432 prop for low to mid 40krpm at the prop

What is being suggested above is good for low 50krpm at the prop and there is no surprise that he blows carbons at those rpm. I blow them at 40odd krpm. Given they are suggested for up to 25krpm then we are all having fun.

Some guys use high rpm for speed and some go for prop dia. I like rpm. It sounds nice. :banana:

what is the physical size of the 3600mah battery? You may be asking for a lot to find a boat to carry that and still perform!

[Meniscus]

It looks like you have some good components to get you started. The motor mount you are referring to is sold here on OSE: http://www.offshoreelectrics.com/proddetail.php?prod=ose-80100

If you take into consideration that:


your lipo measures roughly 5.5"
your ESC measures roughly 2"
your motor measures roughly 3"

Then you're talking about a model that has to have 10.5" worth of space up to 13-14" when you consider the receiver, stuffing tube, etc., without having to cram components in. This means that you'd probably be in the 17-18" model range in order to fit this configuration and allow for COG (Center of Gravity) adjustments.

My concern is, with your lipo being 2s or have a nominal voltage of 7.4V and the motor being 3600 KV, you are looking at 26,640 RPMs before considering loss due to driveline, slip, etc. Many of us are running RPMs more in the 33k to 36k range for sport boating.

You have a few options when you add all of this up. With the lower RPM, you could run a larger prop to make up the difference. Of course this will result in a larger amp draw which shouldn't be an issue for the lipo, but could be for the motor and the ESC.

Another option you have is you could pickup a 3s lipo at 11.1V. This would result in a high RPM, but would allow for smaller prop and result in less torque roll.

Regarding a hull for this exact setup, a good option might be a mini Sea Drifter at just under 18". You can see a picture here. (http://forums.offshoreelectrics.com/album.php?albumid=19&pictureid=813) This one is mine, but I might entertain letting it go. I don't know what your budget is and I don't remember seeing your goals for this build. This specific model is a little taller and your lipo may fit sitting sideways in the front.

Anyway, just a few ideas if you are intent on using the equipment you already have. Here's a link to one of these new, along with a video. (http://www.novahobby.com/brushless-mini-drifter-racing-boat-p-90.html)

I hope this helps. :thumbup1:

My Oncilla 430mm cat for mini hydro currently running on 3s1p 2300mAh A123, Mega 16/15/2, Castle Pheonix35, 1mm wiredrive, X427 with about 3/5ths its original blade area.
For reference the European Mini Mono, Mini Hydro, Mini Cat(where existent) and Mini ECO(the only Mini class which has been adopted by Naviga and gone worldwide at the moment) classes are all for hulls of 450mm and under(around 18") so there a decent and growing number of hulls in this size range.


http://i22.photobucket.com/albums/b310/nativepaul/oncillia001.jpg
Not the prettiest boat ever but function over form, the cockpit is that shape to fit the gear in and it does only just fit.

http://i22.photobucket.com/albums/b310/nativepaul/oncillia012.jpg
No room for or need for velcro to hold the battery in, it hasn't got anywhere to go, what you cant see here is the motor and servo, the servo is hidden in the tailpipe, although it has since been relocated to the starboard sponson.

http://i22.photobucket.com/albums/b310/nativepaul/oncilla004.jpg
The motor sits up front in the cockpit to maintain CoG and keep the bend on the wire to a minimum. Seen next to the battered and abused old 448mm Firecrest which it replaced, designed for a lot less weight and a higher top speed the sponsons are a lot narrower and there is much less tunnel lift.

Paul, I really like that cat. I have a few questions for you if you don't mind. Where's your COG and also, do you have any other pictures of local guys that have similar small boats?

Thanks for the input guys!

[NativePaul]

From memory the CoG is at about 40% now, was 30% in that photo of its first wetting with its arse under water, but it was too flighty there.

No similar boats, I believe I am the only one racing cats in Mini Hydro, I know I'm not the only one that has a mini cat but most are the scale type that are too narrow to compete with a rigger for ovals, although I have heard rumors that someone has made a self-righting F1 cat for this season. No close up pics sorry, I'm running on a crappy copy of windows without any service packs and Linux at the moment and neither will recognise my USB2 external had drives. Our first race of the season is on sunday assumeng my car makes it there, which is not a foregone conclusion at the moment, I will take some close ups of the mini classes for you, no action shots as I should be running. till then best I can do you is this closer shot of the Oncilla and a mini rigger.
http://www.astecmodels.co.uk/gallery/albums/uploads/Nats2009/nats2009_43.jpg

Theres a thread about my Oncilla here (http://www.astecmodels.co.uk/bb3/viewtopic.php?f=18&t=791) if your interested have a look, if your really interested I have the WoF templates on paper, we may be able to come to an arangement.

Those look neat. I need more time to build boats, looks cool.

I have finally seen a cat with a wider aspect ratio than the mean machine now!

Brian

[Meniscus]

Great info Paul! This kind of input captures the spirit of this thread and is exactly what I had in mind when I started it.

I am very interested in the design plans and your lessons learned. I'm not so much concerned about the action shots, but definitely take lots of pictures of the models not on the water. As we begin to generate more interest in micros and minis here, it will help to show what the rest of the world is doing.

With regards to your car, remember there are a few things you should always have in the trunk. They are as follows: #1 Duct Tape, #2 Electrical Tape, #3 Zip Ties. If it can't be fixed with one of those, it probably doesn't need to be fixed! J/K, LOL! Realistically though, a set of pantyhose or extra serpentine belt is good as well as Starting Fluid/Ether. A cell phone isn't a bad idea either!

I hope you make it to the race!!! If I was there, I'd certainly give you a ride.

[Meniscus]

Paul,

How did your race go? Did you make it?

[NativePaul]

Yeah I made it, got the car fixed on Saturday, but my brain and my battery box didnt make it so the race didnt go for me, I did stay to do dutys and take some pics though. the wind was blowing in the worst possible direction and it was rougher than I have ever seen that lake before with breaking waves on the course, and conciquentially the micro classes were not very well supported we combined the classes to get a race but had only 4 starters, 3x mini monos and 1x mini ECO all selfrighting, after seeing the first heat I wasnt to disapointed about not being able to run, I dont think my Oncilla would have stood a chance.

Another Eagle, this time powered by a Mega 16/15/4 and 39mm prop, I forgot to ask what the LiPo was but from the low KV I would guess 3s (Electra (http://www.electrafying.com) my local race series, has a 43v maximum voltage limit for all classes and restricts power with a pack weight limit)

Befu, wider aspect ratio than the MM is an understatement, I was very suprised when I got my MM how narrow it is considering the good reports I've had of its handling, it isnt any wider than some of the german cats, my Oncilla is only about an inch or so narrower despite being a foot shorter.
http://i22.photobucket.com/albums/b310/nativepaul/willenlakemicros2010039.jpg
Because its carrying a lot less weight, 5-700g instead of about 2kg the ride plates are much smaller so although it is narrower than the MM the tunnel is considerably wider.

Here's a video for anyone interested in what micros can do:

http://www.youtube.com/watch?v=9BuiITad0dk&feature=player_embedded#

[Amp User]

Most of this thread shows what I would consider mini boats.
Micro boats are really down in the 16inch range. Nano boats are under 9inches.

Here is my10 gram out runner powered original micro rigger design.
weight ready to run 4.5oz.
Self made 20mm metal surface prop.
Rino 20C 3S 360mah Li-poly cells .
Radar confirmed 24mph with a 2009 Bushnell Velocity Gun on 37.4 watts.
No load 36,400rpm checked with a laser tach.
Note the motor uses silver winding wire for max performance.
(There is no boat going faster on a 10gram motor currently in the world that I know of and I have been watching for it.)
Anyone else willing to try to go fast on a 10gram motor? Prove it lol.

I replaced 248mah back into the 3S 460mah pack after the run in this posted video. Actual motor time 4.46 mins burning average of 55.6 mah per min.
It would take 8.27 mins to run the pack to 0 mah. Watt meter shows 12.4v .92amps no load at 11.3w. Average amp draw under load was 3.34amps,that's average watt draw of 37.4w. :buttrock:

Beyond Spec Races; All (types of boats) should be based on weight of motor for proper races along with cell count and mah range. Size doesn't matter after that as the designer will build to suit his power package.

The goal was to have a rigger ride high on its prop spinning as much rpm as possible from of one of the smallest outrunner motors on the market today.
To perform balls out with high rpm to give the operator the joy of performance from a very light and small rigger at minimal cost! This was made to enjoy small local ponds near home or right around homes. The size is not to harm turtles, birds or upset home owners with annoying activity and noise.

There is enough room for up to 26 grams of (out runner) motor. The design is stout enough to handle 45mph in moderate water conditions. Of course make fatter boats and you can shove 300watt systems in most sub 15inch boats with ease. The tub on this rigger at its widest point is 1.25inches and 1.15 inch tall in the belly area for the motor.

Enjoy the vid after about 4 laps I settle in close to the shore line.

Back in the day we had small, med and large boats. Times have changed.

Race classes by motor weight is probably the least fair way you could possibly run a class, if one person can afford a 90% efficient motor and another can only afford 80% then the guy with deep pockets has double the output power available to him before overheating his motor than the other guy, if you have a set run time with a set battery energy the guy with deep pockets only has about 12% more output power, which is what we see here, guys with feiagos and zippys can compete against guys with lehners and thunderpowers and actually have a chance of winning as good setup and driving can easily make up for 12% more power which should yield a boat 4% faster down the straight, doubt even the best drivers can make up for 100% more power which should yield a 25% faster boat.

[Meniscus]

Kyle, thanks for sharing your build. What prop were you using?

Paul, I was just talking to one of the local guys about the approach you'll are using to level the playing field. I really like the thought process.

[Amp User]

Spec races that require the use of only a handful of preselected motors is for sure the best way to level the field with the same done for the batteries. I was refering to all the other races, when any motor brand is used in a given size hull. Pardon me for getting off subject.

Large, Medium, Small/Mini, Micro, Nano

[NativePaul]

HydroNigel is definitely the man to beat in Mini Hydro, he always builds light and VERY fast boats, last time we raced was at the 08 nats, he won, I came second but that doesn't tell the whole story, he was on another level to the rest of the field, 4 laps up on me after our best two 5 minute heats.

I haven't seen that particular boat run, but I wonder if he gets the runtime on that setup or runs his laps then pulls in till the end, the Het 2w 4800 is a clone of the mega 16/15/2 that I use and on 3s 1500 LiPos should be spinning a few K higher, about 50,000rpm.

[Amp User]

How small do you want to go as far as micro and how heavy is the starship?

[Meniscus]

305MIAMI,

There are several available throughout the world. Amp_User's question is very appropriate.

In addition to his question:
What size are you looking for, what do you want to do with it (oval, small pond, swimming pool, etc) and what speed do you want to go?

[4X4FABGUY]

Hi Guys, heres a pic of a couple of my little guys. The one in front is a wood hydromite I built from plans I got free and scaled down 14 inches. It has a mystery brand 3000kv outrunner and 25 amp spd con. I run a rhino 40c 3s 1050Mah lipo. The prop is a 432 cut down to 430, detounged and very thin and sharp. Its crazy fast. Very fun to run. The cat is a carbon fiber micro scat cat from BBY. Its now an empty hull, I am still looking for the right set up for it. Mike M http://i758.photobucket.com/albums/xx224/4x4fabguy/100_1425.jpg

[Meniscus]

Mike, those are some good looking micros, nice builds. What setups have you tried in the micro scat cat? I've been looking at picking one up for quite some time and have crunched numbers and setups. Send me a PM and I'll share with you my thoughts on setup.

Can you confirm where you got that turn fin for the hydromite?

[SweetAccord]

I wanted the ATOMOS a year ago at one point but then realized parts are non existent and support would not be a phone call away. Also, I've seen it run and was not impressed with the handling, seemed to bounce a bit and not handle corners well. It looks neat though! Instead I purchased a Starship from Mini Cat Racing and can't be happier. Great quality and great support. It has parts that are available and it's easy to setup and run. Motors are abundant as props and hardware.

Jim is great with support and is always very helpful, actually too helpful? We end up talking forever and it's wonderful, he seems to have a lot of time to help you with your needs not "limited free time". The Starship is a blast to run. I always get a crowd that gathers with 50 questions about it. I'm still tuning it with different props and batteries and am getting close to where it runs great. So far been using 1800 and 2200 3s (1550 are on the way) Lipo's and the 34x32 metal prop with a 3600kv 20-40 motor. Nothing gets over 120 degrees.

I like the Mini Cat line so much that I ordered the Micro Hydro. I'll post thought and results once I have them and will likely do a full review on both.

Thank you.

[NativePaul]

RE the above post: I dont get it. What parts do you need for a Hull? If you damage it you fix it, patching with glass most likely, if you damage it beyond repair you cry then buy a new one. Motors, props and hardware aren't specific to a hull and there are just as many suitable for the Atomos as any other hull of its size. The comparison the Starship is apples and oranges the starship is a rigger and a much bigger boat, while the Atomos is very rigger like in its design and handles very well for a full bodied hydro, it is still a full bodied hydro and won't handle corners as well as a rigger can, and due to the size difference given the same size waves a small boat will always bounce around more than a bigger boat, that nothing to do with the boat design its just the physics of scale.

If you want a small full bodied hydro the Atomos is one of the best, but check out the MHZ mini Miss Madison too, thats scale, is still hellishly quick and if racing on a normal size oval turns plenty good enough, if you run a 2 buoy mini oval course the Atamos will beat it though with its wider stance cornering tighter at full speed.

[SweetAccord]

RE the above post: I dont get it.

What parts do you need for a Hull? = None it's ARTR.

If you damage it you fix it, patching with glass most likely, if you damage it beyond repair you cry then buy a new one. =This is true for all boats not sure what the point is to that statement?

Motors, props and hardware aren't specific to a hull = Sure they are check Offshore and Mini Cat's site for parts. They are specific to these hulls, they have to be cause of the size.

The comparison the Starship is apples and oranges = Sure, I never said that they are the same boat only point is that both are fast and small and one has parts available and full support not "limited free time" support.

The starship is a rigger and a much bigger boat = not really it's about 16" long, that is pretty small.

The Atomos is very rigger like=I don't see how it's rigger like it's a Hydro like you said.

The Atamos will beat it though with its wider stance cornering tighter at full speed. = The Starship has a much larger stance in width in the front. I have tried to flip it and can't seem too. It turns like it's on rails and I don't even have the optional turn fin on it!

What are the Atomos hull measurements? So we can compare the width?

Don't get me wrong the Atomos looks great and all but getting parts (if any as none are listed anywhere that I was able to find) and support from over seas is difficult. Like I said, I looked at the ATOMOS for over 3 months of web searching and reading forums, and don't find anything for parts or phone support.

Peace.

[SweetAccord]

I just got the Mini Cat Hydro and it's sweet! I will be posting video's on the Starship soon.

[NativePaul]

What parts do you need for a Hull? = None it's ARTR. = I was trying to ascertain why you would need parts for a boat hull, and the atomos is sold as just a hull by the way not a RTR

If you damage it you fix it, patching with glass most likely, if you damage it beyond repair you cry then buy a new one. =This is true for all boats not sure what the point is to that statement? = As above just trying to ascertain why you think you need parts for a hull.

Motors, props and hardware aren't specific to a hull = Sure they are check Offshore and Mini Cat's site for parts. They are specific to these hulls, they have to be cause of the size. = No there not, just specific to a size of hull, minicat, HOtR, ETTI, MHZ, Astec and Dr Psycho all do hardware that will fit the Atomos as well as any other mini size boat. Feigao, Mega, HET, Nue, Lehner,tenshock and many other chinese companys make motors suitable for the Atomos or any other mini sized boat. Octura, Graupner, Hor and Tenshock all make props suitable for the Atomos or any other mini size boat.

The comparison the Starship is apples and oranges = Sure, I never said that they are the same boat only point is that both are fast and small and one has parts available and full support not "limited free time" support. = The Atomos is a bare hull, no parts or support are needed.

The starship is a rigger and a much bigger boat = not really it's about 16" long, that is pretty small. = Please forgive me, here in the UK there are 2 starships, one called "starship" (hydro1 size) and a "mini starship" (what you know as the starship) I forgot that there was only 1 in the states so when you said "starship" I was thinking of the bigger one.

The Atomos is very rigger like=I don't see how it's rigger like it's a Hydro like you said. = primarily its length to width ratio, while not as wide as a rigger it is much wider than a scale hydro, but it also has little in the way of tunnel lift, as the tunnels is exceptionally thin and it has no air traps, what lift it does have is as far back as possibe as seen in the pickle forks which start at the back of the sponsons, it is not a rigger, But like the insane sport hydro its as close to a rigger as it is possible to get while still being a full bodied hydro, if you saw the bottom of one in the flesh you would get it.

The Atamos will beat it though with its wider stance cornering tighter at full speed. = The Starship has a much larger stance in width in the front. I have tried to flip it and can't seem too. It turns like it's on rails and I don't even have the optional turn fin on it!

What are the Atomos hull measurements? So we can compare the width? = The Atomos is 420mm long and 230mm wide, the ride pads go nearly to the outside, for comparison the scale MHZ mini Miss Madison is 435mm long, 225mm wide and the ride pads are tucked in under shallow anti trip angles.

You are all quick to pass judgement on a custom manufacturer. Have you considered that they may have shut down the daily operations to do testing and travel for races?

I would be patient. If you are looking for a more immediate solution for your hull hunger, consider talking to Randy at BBY. He has many micro hulls that aren't displayed on his website that are in stock and ready to go. If you want a custom version in Carbon or Fiberglass, he can accommodate as well. I can personally guarantee that if you call him, you will get him on the phone.

Meanwhile, I'll try to see if I can reach Stephan at Lindenau for you guys.

If you could get hold of Stephan that would be great!

Update:

I've been talking to one person who has the ATOMOS and as much as he seems to like it also says how it's finicky to setup. He's made it clear that it took him a year to finally get it dialed in. He also mentioned how parts are non-existent as this is all custom made so if you break it you have to fix it. As much as I like from what I've seen on this boat I'm not 100% sold on it unless you are the type that like to make your own parts and do not need support etc.

I have e-mailed them 6 months ago and have not heard anything still. This is a good example where a company like OSE and MiniCat Racing and others are there for you and have the parts and has the support to back up the product which I have been more than happy with. I think it's sad as that boat looks very nice and I would love to own one.

Works great on smooth water but slightest ripple and it was all over, mines launched out of a ripple into a stationary rock, didn't end up to well for the cat:(

[Meniscus]

Sorry to hear that. I haven't run any of the small cats yet, but my understanding is that for a general rule of thumb, set the strut very high and push the COG as far forward as possible and still get up on plane.

Did you ever fix her up? You know there are a few very nice small cats available in the marketplace. I've been toying with the idea of building one next Winter.

[jacksblack]

I bought a sv27 since that which is going through a re build and I am trying to find a 32" cat to make a twin engine fe.

If a new mini cat hull pops up at the right price I will get another one, I love the mini cats they are so much fun and no body expects them to go as well as they do with a brushless in them.
