The following is how I convert a Pro Boat Mini-Cat to Brushless.
I have lost my Pro Boat Mini-Cat to Davey Jones. The kind folks at Pro Boat (Horizon) replaced her with a Mini-V. I questioned the replacement, they stated that the cat, due to the rename, is not available. The Mini-V is the closest replacement. I took the V to my LHS, they exchanged it for me.

Now on to the build progress...
Parts list:

3/16 brass tube.
.098 flex cable w/ 1/8 stub/prop shaft (Octura (http://www.offshoreelectrics.com/proddetail.php?prod=oct-oc098L-24c))
Motor of choice. (I'm using this ammo 28-35-2700 (http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXLWY0&P=7))
ESC of choice. (Team Orion Captain-35 (http://www.teamorion-avionics.com/Brushless+ESCs/Captain+35A))
Mini Hydro Hardware (From OSE (http://www.offshoreelectrics.com/proddetail.php?prod=mcr-mhd&cat=69))
Prop of choice. (x427 (http://www.offshoreelectrics.com/proddetail.php?prod=oct-x427))
2 part foam. (This stuff is awesome (http://www.hobbypeople.net/gallery/864206.asp))

I removed everything from the hull except the linkage boot. I inserted a coarse rattail file in the tube from the transom end. Rattail files are thicker in the middle. Once the file bottomed out on to the tube, I gave it a slight right twist, till I heard it pop.
http://www.diegoboy.com/misc/100_2049-sm.jpg (http://www.diegoboy.com/misc/100_2049.jpg)


I used a small pair of vise grips on the front of the stuffing tube. I grabbed the tube and gave it the same slight twist till I heard it pop. Then I removed the Vise grips.
http://www.diegoboy.com/misc/100_2051-sm.jpg (http://www.diegoboy.com/misc/100_2051.jpg)


I used the rattail file still locked down on the tube at the transom, and twisted the tube to the right as I pulled it out.

Drill the hole at the transom with a 3/16 bit as far as it'll go. Then file out the hole at the other end. Mark the 3/16 tube length with the original tube removed. Cut the 3/16 tube to length. Insert the cut 3/16brass tube in the hole at the transom, guide it through the other end, and extending about 1-2mm at the motor side (like the original was).

Make a 3 sided cut in the tub where the rear of the motor would be to make a flap. Fold this flap back. Get the 2 part foam. Hold the boat with the bow pointing down & hold the flap open. Mix 10cc of part A & 10cc of part B. Stir for about 10 seconds, then pour into the hole with the flap. This stuff does NOT push like the spray foam. it remains very soft like the fizz on your Coke or Pepsi. once it stops expanding, then it starts to set. Because of that, it won't separate, or bloat your boat. Once set, trim any foam that may have come out the flap, then close the flap and seal with epoxy mixed with paint for color.

There is absolutely no flotation foam in this boat from the factory. and it DOES SINK! I know first hand. The pocket of air in the bow didn't do a stinking thing.

Here's what it looks like after the foam is set.

I went to the LHS today to get the flex coupler. .098 to 1/8. They are out. the last one sold was to me and it's at the bottom of the lake. It'll be in stock next week!

I picked up the drive dog, and an X427 prop. It's not sharpened or balanced as yet.

I also picked up the ESC it's going to run. I couldn't pass it up, because it was in my price range! (Cheap).
Specs are on the link in the OP

I installed the motor, and finally got to cut the flex cable to length.

When I can score the parts for the sub at a whopping $33.99! :laugh:

That LHS has about 20 of those ESC's at that price. The bay sells them for over $50
The 45A version is $39.99

Diegoboy,
this build really looks cool. i am sorry you lost your first one. i am surprised there is no float foam in that hull. even worse that there is no bow access. that two part foam looks great, it's better than the spray stuff then? if i were to do the same thing, would you help me out?

Diegoboy
01-13-2008, 10:55 PM
Welcome Eric.
I'd be happy to help/guide you. The 2 part foam I got is awesome. it pushes outward as much as the foam on top of your glass of cola. When it's done expanding, it will then harden. It simply doesn't push like the spray foam will.

It looks good, man. Does it affect it having the rudder on the side?

Diegoboy
01-27-2008, 11:53 PM
Thank you!

I'll find out.
Offset rudders are supposed to be more efficient because it's not in the path of the prop wash. I must say that it being offset, helped in the balance of the boat since the RX & ESC are on the opposite side.

What about esc and motor cooling. Especially when using vacuumed formed hulls

Diegoboy
01-28-2008, 08:13 AM
The motor is rated at a nominal voltage input from 11.1V - 18.5V. I'm on 11.1V
The ESC is rated for lipos from 2-6 cells. I'm in 3 cells
Max surge current of the motor is 30A while the ESC is 35A with a max of 45A.

I'm not anywhere near the limit on any component. I don't expect too much in the way of heat. If I'm wrong, the rudder has a pickup! :tongue_smilie:

I did the same conversion with my mini V but when I twisted the stuffing tube out it cracked the hull a little near the strut. No big deal, I fixed it with a little ca glue and marine epoxy. I used a pulso 40amp esc, a feigao 16s 2500kv motor, detounged x432, and 3s 1650HV 15c battery. The battery is the weak link but the boat flies. It litterally jumps like 2 feet out of the water if you juice the throttle. I'm going to order this http://www.rcworldwide.com/v5/product_info.php?currency=USD&info=p701_Delta-Force-16--Mini-Hydro.html . and this http://www.offshoreelectrics.com/proddetail.php?prod=mcr-mhd&cat=69 which is the same set you ordered. Do you think this will be a decent set-up? The hull is only 16" so I figure I'll have a pretty quick little micro Hydro on my hands.
I noticed on that site I could just get a micro hydro boat for like $231. but that kind of defeats the purpose of finding a hull for the stuff I got. I also would like to build my own boat but I'll have to figure out what it'll cost for hull, hardware, mount, shaft and a pushrod if the mini-v one doesn't work.

Dale Koblitz
01-30-2008, 12:54 AM
I have a question for you. The hardware you used is the same I'm ordering for my project and it says to use .094 cable but all I can find is .098. I see you used .098 was there any issues with that?

domwilson

Be careful with these guys. http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback2&ftab=AllFeedback&userid=com-rcworldwide&iid=-1&de=off&items=25&page=2

I ordered a few things from them in the past.
Got the wrong Feigao motor (20XL) and they said that it would cost me more to get the motor I paid for originally (9L). Took almost three months to get a rudder from them and it was the wrong one. Wouldn't take it back. Wouldn't answer emails. I was told that they were pulled from ebay for awhile because of their bad customer service. Part of the learning curve when getting into this hobby. Bad Vendors. You might have better luck.

The same thing happened to my Mini-V (not this Mini-Cat) when I did this to her also, she cracked like yours. She also had a serious issue with torque roll. Being a V hull, she had no left / right stability against the torque. This Mini-Cat, on the other hand, does. It's twin hulls will give her much more stability in defense of the torque than a V hull. Also, she's 14.5" long, only 1.5" shorter than that hydro you want to try. That hydro looks sweet, if you can find a US supplier for one.

The .098 had no issues. You will have to shim the strut if you go with a 1/8 stub (prop) shaft. If you stick with the 3mm shaft, your prop choice will be limited.


...Oh, If you only did the flex shaft mod to your V and left the stock steerable outdrive installed, that also adds to your instability with your V. You hear how the steerable outdrives handle like an 18 wheeler? well imagine a twin turbine 18 wheeler. :thumbsdown:

Do you really think it will kill the handling? Im really eager to do this but dont want to rob a bank to pay for all these parts I need. If I buy all the parts you mentioned on the first page minus the Mini Hydro hardware and I cut the shaft to fit the stock outdrive run it a few times and figure out that handling is crap and decide to shell out the money to get the Mini Hydro outdrive will my cable still fit or will I need a New one?

Diegoboy

The steerable outdrive modded with the .098 flex shaft alone will not "kill" the handling.
It's that mod, coupled with overpowering the boat with a brushless motor that will do it.

Sorry... I missed this part.
The stock HW needs a longer cable than the Mini Hydro HW. So your cable will still fit with maybe a tiny bit of trimming.

The mod won't hurt the handling (if anything it will help) but he's saying with all the power of BL the upgraded hardware will handle much better then the stock stearable outdrive. But if you are going brushless it's a must to at least do the .098 cable drive because the stock streight drive with the plastic u-joints won't hold up and will cause lots of vibration and resistance causing unwanted heat. So just do theflex drive conversion and you can allways switch the hardware out later. Even if your going to do just run the stock motor the flex is a good upgrade. Some run the upgrade and a 3s lipo which gives great speed.

I use a 40 amp pulso esc and a 3s 1650hv 10c which is not the best battery for the job but it is working fine for now. The guy at the hobby shop said the 10c would be fine but once in a while the low-volt will cut-off for a second or 2 but then comes back on. I am going to order the cat hull I linked earlier since now the strut screws stripped out also and the V is just way overpowered. Diego your boat looks good. It porposes a little when you let off but settles down well when your on the throttle. Diegoboy, did you get the radio I sent you yet?

Diegoboy

I did the same conversion with my mini V but when I twisted the stuffing tube out it cracked the hull a little near the strut. No big deal, I fixed it with a little ca glue and marine epoxy. I used a pulso 40amp esc, a feigao 16s 2500kv motor, detounged x432, and 3s 1650HV 15c battery. The battery is the weak link but the boat flies. It litterally jumps like 2 feet out of the water if you juice the throttle. I'm going to order this http://www.rcworldwide.com/v5/product_info.php?currency=USD&info=p701_Delta-Force-16--Mini-Hydro.html . and this http://www.offshoreelectrics.com/proddetail.php?prod=mcr-mhd&cat=69 which is the same set you ordered. Do you think this will be a decent set-up? The hull is only 16" so I figure I'll have a pretty quick little micro Hydro on my hands.
I noticed on that site I could just get a micro hydro boat for like $231. but that kind of defeats the purpose of finding a hull for the stuff I got. I also would like to build my own boat but I'll have to figure out what it'll cost for hull, hardware, mount, shaft and a pushrod if the mini-v one doesn't work.

This is a nice Hydroplane, what colour did you get? i got Green.

I'm putting a 1615 2 turn Mega in it with a 70 amp esc, lipo 2S-1500Mah 25C and a x427 prop. RC worldwide had (i bought the last one) the blue rudder (micro) for $15. I'm using a Fullers strut with .130 cable and octura coupler. Should bea handfull!:rockon2:

Excellent build and very nice thread on your Mini-Cat! I tried to find the Team Orion Avionics Captain 35A or the 45A ESC, but it's discontinued. I wonder what would be a good replacement? Is it an Aircraft or Car/Buggy ESC? Do you need a Pistix Adapter?

Any 380 size BL motor will fit but you don't want to get to crazy with the KV's. And by asking what works with the stock set-up I'm assuming you know you have to get a BL ESC and a standalone reciever?

Hi guys, I'm new to the forum and RC boats. I race 1/5 scale cars and fly RC electric planes with lipos. The youtube video had me hooked. This is my first RC boat. I'm not toally clueless to RC stuff but have some questions on this build. I have the mini c boat already and ordered all parts on page 1 except for the hardware outrigger set.

*What kind of epoxy is good to seal the hull hole you need to make for the foam install? I'm not aware of many glues other than goop that will work on this type of plastic. I've read there is a permatex plastic welder epoxy? Is that good for this plastic? Also do I use same glue to glue in the replacement stuffing tube?

*Does the .098 flex cable fit in the stock stuffing tube? Kind of unclear from some of the replies. Also if I don't buy the mini outrigger setup, can I run the flex cable thru the stock steerable outdrive? Even with a lipo and brushless? What ultimately will happen?

TIA.

*EPOXY, I use a Permatex product from the auto section called COLD WELD. Be careful if you use ut since it sets quite fast. Treat it like 5 minute epoxy.
Always sand the area to be glued with rough paper 80 grit or so and clean with alcohol before gluing.
You can use JB Quick Weld, it is about the same as the permatex stuff. There are other epoxies but its good to go with a good name brand and from a place that turns its stock alot.
You can use the same glue for the stuffing tube or some very thick CA like Slow ZAP.
I used a new piece of tubing because the teflon fit better.

Yes you can use the stock outdrive but for brushless it depends how insane you want to make it. You don't want to have to fish it out after it flips, that a drag:cursing: ....Also with brushless you may need to lube the cable more often if you are spinning alot faster.

I would try to post pictures but I'm a little busy this moment.

Of course I did this for my buddies Mini-V but, no fear the same setup will work on the cat too :rockon2:

Now that I fixed his boat up he is 200% more satisfied than before.

If you haven't changed the battery connector to a full size Dean, I would, seems to help alot.

You may need a new coupler that is 2mm at the motor and .098" at the flex end.

I made my own, I have a lathe.

Hope I was some help.

P.S. Don't use a Mamba BL system, at least not the motor... the ESC is o.k. (Sidewinder is cheaper). The mamba motor is too small and will overheat.

This is a nice motor, https://www.unitedhobbies.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=4197&Product_Name=HXT_2445_(370L)_2900kv_Brushless_Inru nner

It is 24mm in diameter, not too shure if the stock motor is 24 or 28mm. If it is 28mm Steve has some nice feigao 380 motors in his online shop OSE, just click over to see them.

Thanks Ray, thats a lot of help. Couple of more questions from the noob. Sorry if they are stupid :) Except for the outrigger, I have all the same equipment as Diegoboy

*what kind of lube should I use for the flex cable?
*what does the outrigger do exactly? That's for stability while turning to avoid flipping? It seems that thing could add more weight on the back which would cause the front to lift at speed and flip end over end?
*What spec lipo did you run for your buddies build? I have an extra thunderpower 910mah 11.1v but am thinking it will last a total of a minute with this setup? Does the electronic compartment get much leakage in these boats even if no flipping?

06-27-2008, 11:54 AM
Just skimming over the reply 2 your ? I didn't see an answer 2 your stuffing tube dilema. The answer is no. You'll need a 1/8" tube and of course the liner that comes with the flex cable. And b carefull when removing the old tube cuz I cracked my hull doing this step. Nothing a little marine epoxy didn't take care of though. I just grabbed the tube on the motor shaft end with a needle nose pliers and twisted till it broke loose. You'll also need 2 remove the bushings in the outdrive and replace it with brass bushings large enough to accomidate the larger prop shaft unless your using different running gear all together. I built the mini-v with a 2500kv feigao, 45amp pulso esc, and 3s lipo's turning I believe a detounged Octura x432 prop. This boat is ballistic 4 it's size. It will keep up with my moderately modded supervee if you can keep it right side up. It tends to flip or barrel roll if you give it 2 much finger upon take off. I plan on getting a micro mogli hull 2 accomidate the electronics to better handle the power. This hull is just not meant for the power my set-up delivers. Maybe a mini-cat would be much better suited being it is a cat and would have less of a tendancy to roll. Good luck! If you want pictures let me know but it's not nearly as clean as diego's old cat!

cafe00
07-19-2008, 03:25 AM
For those copying this build, I found out the hard way. The flex shaft setup mentioned will not fit the bearings for the outrigger. Here is the info for what's needed from the distributor below. Also a 1/8 stuffing tube is probably better suited as well. The one listed is also too big unless you want to seal it off with a lot of shoe goo...
The bearings are for a 3mm shaft. You need to order the flex shaft with a 3mm shaft like this one.

ray schrauwen
07-19-2008, 08:02 AM
I found that a piece of 5/32" K&S tubing made a great bearing sleave for the strut.
It seemed loose so I put a dab of goop to keep it in place. That way an Octura flex cable system would fit nicely and then I could use any standard 1/8th" props.

Also, if you drill out a Graupner Carbon prop with a 7/64 drill bit(new bit) and then use a 5-40 Tap (from local supply store) you can thread it easily so they will go onto the shaft, just put a 5-40 locknut behind it.:w00t:

OK, yet another noob question. What's the best angle of attack for the prop? Should it be deeper in water or higher up? If I angle the outdrive similar to angle of shaft - making it Deeeper in water - it seems to go slower. Is this right? i'm trying to find balance between angle and putting too much bind on the shaft. I'm running bushings and not bearings so want as little friction as possible but still as much speed as possible :)

She may go faster when the prop gets lowered and has more Bite!

Hey Diego, do you mean lowering the whole strut, or just changing the angle?

i paid $12 for the ose strut, $10 for the flex drive system, $10 for the prop, $12 for the rudder, and $20 for the motor, and $4 for the metal gear servo, and a homemade watercooled motor mount from brass sheet and tubbing, and lastly $4 for the esc watercooler. i kinda had to save money when it came to the motor as i dont have much cause im 16 lol

Old thread but..
Diegoboy the 2part foam link doesnt work for me..where did you get it from and what is the stuff called? Did it make your mini cat unsinkable? What about filling it into the sponsons also, would that make it safe from davey jones locker?

Oh sorry to hear that. Is that his secound mini cat lost? 2-0 to mr Jones :(
Im glad I just won a lot of 3 mini cats on ebay then (122$ for 3, I think it was a bargain), because if this is how mini cats usually end up Im gonna need them all..Im new to rc boats so I dont really know what to expect..
But I would like to try to avoid sinking them if I can help it, so I want to try out the 2-part foam and put it in the front and on the sides inside the sponsons, but what is the stuff called..?

Thanks for the link damfurst. what density did you use on your mini-c, low, double or quadruple? You say you have used it with sucess on mini c, does that mean it cant sink anymore? Did you just do the front?

I used low because it was the cheapest and it works great. I have not lost any boats if they flipped since using this product. I have done 3 mini-c's. Two just the front and the other one more like 2/3. Just the front compartment is really all it takes to keep it from sinking.
