Eodman thanks for the heads up :buttrock:
I looked at them on e-bay then called Aeromarine direct. There sending me a MM, yellow with decals for $60.00 plus shipping $15.00. There are lots of MM builds on this form so I won't have to hard a time making up my OSE parts order.

[ice329]

Thanks for the heads up. I just called and picked up one. Nice guy and easy transaction. They have about 100 of these boats there looking to place, $60. Here is the number if someone wants one. 302-628-3944

[RiverRat]

Before you guys go tearing these boats up. Went over mine last night. The only thing wrong was the on/off switch was bad. Motor fired up no problem.
Will be making a proto type bolt on motor mount for 540 size electric today. Should have the bugs out by monday. This is going to be super light, fully adjustable, and no need to remove the original mount.
Any takers?

[sewerpit]

waiting for mine . glad to hear you were not disppointed . will wait to see what you do. keep us posted pics and info are a drastic help for us newbees. cant wait to start on mine, fellas for 60 bucs how can you go wrong

[sdartt]

Riverrat
Did you get the $60 MM? If what came with beside the on off switch. Mine should arrive today or monday.:beerchug:

[RiverRat]

Well no, I bought 4 of them. Since I am a repeat customer he gave me a great deal. Came with everything except the gas tank. Un opened Radios were also included which I didnt even know I was getting.

[RiverRat]

Boats are beautifull. The only water damage is the nut on the rudder has surface rust. One had some surface rust on the flex shaft but is not pitted, fine to use. Better then expected. Not a blemish on paint or hardware.

[sdartt]

Thinking of installing a Speedmaster Dual pick rudder on a MM. Like the idea of cooling for motor and ESC seperate. Part # ros-rud-dualpu- with a 2 inch set back and trim about 3/8 to 1/2 inch off the lenght.
Any one gone this direction or is it to much rudder. power will be a Neu 1521-1D:confused2::confused2:

[Darin Jordan]

... power will be a Neu 1521-1D:confused2::confused2:

You are going to put a 1521 1D in a 29" Mean Machine??? :ohmy: Are you planning on running 4S with this?? Is it a SAW setup??

There are going to be a TON of watts wasted there... WAY too much motor for that hull... On 4S that's 44,800RPM or so...

Not to pry... maybe it's none of my business... but what are you intentions for this boat??? SAW, Sport, Oval Racing??

[sewerpit]

darin, what do you suggest for the mm hull? just wanna have fun, do some oval racing and get up in the low to mid 50's

[Darin Jordan]

darin, what do you suggest for the mm hull? just wanna have fun, do some oval racing and get up in the low to mid 50's

For a Neu... I'd suspect that a 1515 1Y would be more than enough power for that hull... At the MOST a 1521 1.5D... but you'd have to be able to run a decent diameter prop to run the later... (X447, X450, etc...) I also think that it would be overkill as well...

I think Jay Turner did an article on this hull and converting a MM to Lipos from NiMh awhile back in an RCBM magazine... I don't recall which motor he used... For some reason a 9XL comes to mind, but I also think there was a geardrive involved... I'll try to look it up tonight and let you know...

My choice, without further info, would be a 1515 1Y on 4S2P and run it direct-drive... That would give you LOTs of power and good runtime on a reasonable prop setup...

All just my opinion, of course...

[sdartt]

Thanks for the good feed back. I picked the 1521-1D from a build on this form. I had a feeling it may be to much and you confirmed. I change to a 1515-1Y. I will be oval racing.
I see your from Renton, I moved to Florida about 5 years ago, did live in The Parks on the south east side of Renton on the hill.
I see why you go for the O'berto hydro, I use to what the old SloMo's when I was a kid.:thumbup1:

[ice329]

You think the SV powerplant would be OK in this? Maybe running 14 cells or 2 - 7.4 Lipo's

[Spot Me 2]

Sure am glad I paid full price earlier this summer. This make mine worth much less. I might have to pick up an extra hull though.

[Darin Jordan]

You think the SV powerplant would be OK in this? Maybe running 14 cells or 2 - 7.4 Lipo's

I would think it would work fine and provide good speed and runtime while being relatively easy on equipment... You won't likely get the super high speeds from it, but I would think that upper 30s-low 40s would be possible with the right tuning... Maybe faster...

I have setup a 31" H&M Intruder S Cat with a BJ26 setup for use in our LSO class and I expect it to do well... The MM should be similiar...

I don't really have any CAT experience to speak of, mind you, so I'm kind of just going off of my experience with the motor package (extensive at this point) and what I've seen and read about how these hulls work...

I run a BJ26 or SV27 setup in my 36" 1/10th Scale hydro and it has not problems with it... turning a 45-47mm prop...

Go for it! Sounds like a VERY affordable setup at this point!

[RiverRat]

Made some time today for an easy motor mount for the newbies. Everything fits fine if using a sv motor and ose water jacket. There is plenty of room left if one would want to use a 540 xl motor. The problem is the size of the water jacket. If using a water jacket larger then the one in the pic then the motor must be slid towards the front which would not allow for enough engament on the collet pictured. Then one would have to use an extend coupler or make a longer flex shaft. The big plus with this mount is you can go back and forth between gas and electric by only removing the four mount screws. I think it would make it more attractive on the resale end. Will make the unit lighter and add cooling before I run it or make the drawings.

[russ722]

hey if any of you guys bought these and dont have a need for a radio box send me a pic and price, just need a radio box.

[DISAR]

Hi,

I could not resist the low price of the MM and I also bought one without the hardware. I read the various topics in the forum for this hull and I have available to fit a Neu 1512/2D (2600 KV) on 4s. What prop shall I use for good speed?
Also regarding the shaft, the tube must have have a single bent (not "S" shape), parallel to the bottom and about 1/4 to 3/16" raised over the botttom. And COG about 33-34% from the sponsons transom. Is that correct?

[sdartt]

Should receive my water logged MM from AM today. I was set to buy another Feigao 540XL-9 but saw the info. on the new 580-8L. What are the FE Guru's thoughts on this combination?:spy:

[sewerpit]

was also waiting to hear on the 580 8l , was looking at the 8 xl for my mm biuld, but will wait on the verdict of the 580 8l

[ice329]

Got mine, its really just about perfect(Yellow). Will be a fun challange to build over the winter. I am thinking the SV power system running 7 cell packs. Mounting it will be some work.

THANK YOU AEROMARINE

[sewerpit]

how about a pic, still waiting for mine probably today or tommorrow too

[yudruln8]

got my mean machine in today everything looks good except for a small chip on the left near the transom nothing a little bondo can't fix now just waiting for hardware,motor and esc to arrive.

Got my MM --- this is my second one. I bought one from Steven 1 1/2 years ago and the one I just got is much lighter than the earlier one!

This one has no reinforcement on the tunnel .... the 1st one had either carbon fiber or extra mats of fiber glass applied!

As far as the hull is concerned it will be great once done. But I have to tell you if I bought this as a RTR gas hull I would be definitely pissed off! The graphics appear to be done well, but when you open it up Good Golly Miss Molly! The mount for the motor and fuel tank is well done but when assembled bondo/adhesive was smeared all over with no attempt made to wipe up the excess! The same for the drive shaft just a glob of bondo no smoothed out on the underside!

If Remy has QC guy he should talk with him ... if not hire one! I would not like my company name on this product!:sorry:

[sewerpit]

got my hull today its in perfect condition, hardware looks great too, the drive shaft underneath was bonded kinda slopy but no biggie , cant wait to start the build. have one question there is something attached to the inside of the left front part of the hull what is that thing anyone know . big thanks to aeromarine got the hull in 2days and for the money cant beat it

[Eodman]

Whats it look like I got the bare hull don't recall seeing anything on mine. When looking at these hulls --- I noticed that they centered everything where as I read to offset the drivetrain to counter prop torque! Maybe its for weight?

[sewerpit]

just called aeromarine, its an added floatation device, some have it some dont

[ice329]

Sewr you have a pic? I think I see the holes where mine was just curious.

I ordered a few little things from Aero to make the build easyer. The servo tray and a few other little things.

Gonna try a SV system with 14 cells, will try a good radio/reciever first if it acts up then I will go with the battery pack instead of the direct BEC

Ah Sewer ---- your's is down right neat compared to my hull!

[sewerpit]

thought mine was a mess. like i said all is comming out . what should i use to get that glue or what ever they used to hold that tray and motor mount down with off? want a nice clean start. does home depot or target sell cf cloth or something i could use for reinforcement ? what type of epoxy should i use to lay that down with?

[ice329]

Why take the tray out. It sems to be the perfect angle and if you pick up a mount from the RivRat mounting a motor will be as simple as 4 screws. I love the foam, a sharp knife to shave off the excess but otherwise its good floatation just in case. I see a few little things to cleaan up like the bond or what ever it is near the shaft, otherwise for the money.... cant go wrong. Always wanted one just never got a great deal till now.

[sewerpit]

really havent decided what to do yet. have all winter long to do it right. will keep all posted and will still ask for lots of advice. gonna work on my rescue boat over the weekend

What has been you guys luck to demo out the old? I bought CF which is the dirrection I planned to go, just not sure how bonded the old parts are to the hull?

I stripped mine out --- wanted to start with a clean slate! Both popped of pretty easy ... then had to get rid of all the bondo!!!!!!!!

[SLAUGHTER_AUS]

LOL, no not tasmanian... thanks though.

[ice329]

I know a lot of people are doing one. I tore into mine tonight. I really wanted to leave the tray and motor mount but the more I got into it and looked at others pictures, I decided to tear it out. Just for some info, the motor mount unit, the radio tray with cover and plug etc all weighed 11.7 oz. I am kinda glad I took it out. . The motor mount will know be made of wood. Not sure if I will put a differnt box in to hold the electronics or not. I probly will because it dont look like it would be easy to keep it dry incase of a flip unless a box is added. I shortened the shaft a little... its getting there.

[highndry]

Looks like a drunk 2 year old glued the stuffing tube in . Scrape all that junk off, tape the bottom and attach with thickened resin from the inside.

Like the aluminium hatch hold-downs. Are they Aeromarine??

Good luck with the build. They resond well to FE.

[highndry]

Sewer,

In response to the epoxy question. Consider West System 2 part.

[ice329]

Quick question and a pic of the mount I made.

On the hardware, does anything go on the tube or does it just slide in and thats it. I have to reset the tube.

[ice329]

I chipped as much as I could, then a hand held dremel with a fine grinding bit and very carefully took it off. I took more off after the pictures. Maybe I can try it out today or tomarrow.

[ice329]

Bathtub test. Auto bailers leak. filled them with silicone. Could not get them out without looking like it may bust the corner of the hull.

[Eodman]

After I got the box and mount out I used a Black & Decker hand held sander with some coase sand paper!

Little help....tuning She runs really nice. I am enjoying this cat. Today I ran it 4 times on just 6 cell Nimh packs. wanted to feel her out before I step it up. First run IB3600 packs and a M445... ECS only 75 (first in cooling line) motor 117, batterys 150+... something not good. swaped the prop, fresh IB3600 packs 1740-3... would not plane. Swaped prop P something the 4 bladed prop, it planed but I didnt care how it ran. Regrouped threw in a fresh set of IB packs and a X642 temps simalar to the M445 ESC 74 Motor 112 packs 150+. Where am I at? Running wet? To much prop? Where am I going with this.... any help. These packs are beasts and they never get this hot. The power plant is a SV system and its running good.

That's a lot of prop for that motor unless the cat is set up near perf.


swaped the prop, fresh IB3600 packs 1740-3... would not plane.
The 1700 series are hydro props, not suitable for cats - unless you know what you're doing, and even then there are far better choices.


Swaped prop P something the 4 bladed prop, it planed but I didnt care how it ran.
The P series props are based on the 1700 series, not good for cats or monos.

Where did you get these prop recommendations?:confused2: They have contributed to permanently damaging your packs. You never start out tuning a boat with large props, always start with props smaller than you think you need....an extra prop or two is a lot cheaper than new batteries.

Your packs are now questionable and may be over the hill. All it takes is a couple runs heating them to over 150F and they will never be the same again.

Most of your props are too big for the MM (and the wrong designs) unless the boat is trimmed well. At full throttle running straight ahead on fairly flat water it should run on the back 3"-5" of the sponsons. If not then it may be drawing too many amps and needs to be freed up. I assume that the driveline is free without binding, you lube the shaft well, and the power wires are short.

Set the CG at ~8.5" and the bottom of the strut about 1/8" above the sponsons and angled up one degree. See if this helps, but your packs may not be able to pull the model now. Let us know how it goes.


.

[ice329]

The props I tryed are just ones I had here. The M445 and X642 are for the SV and the other two I got for the Tunnel so thought I try them, they did not get a very long run. A few seconds at most. The shaft is nice and free. I may try triming it up a little but maybe I need to get a smaller prop. Which are good choices. maybe a X442? I want to run the SV powerplant but on two 7 cell packs

[calcagno45]

ReddyWatts runs the Y537/3 on his MM. I plan on trying this prop on my cat as well. From all indications on the FeCalc, it seems to be an easy going prop with good speed.

[ice329]

OK I am following but I have a silly question. If the SV ESC is a 45 amp unit, it kinda stumps me that even if it was pegged at 45 amps the entire run, the packs should handle that? I would think the esc would get hot. I have a few carbon fiber props that may be on to test a few temps. I will get back on the water and play some more.

[ice329]

I may have found the problem. The strut braket was loose alowing the shaft to go down and flex possably binding the flex but definatly making the strut run negitive. So I reset it, tightened it and will give this a try. Also picke dup a X442 to give that a try also, should be easyer on everything then the X642

[ice329]

OK problem solved. Sort of a combination, part my fault for missing the loose strut. Strut is at its highest position now and somewhat positive, and the boat defiantly does not like 7.2 volt packs. First run with new adjustments, motor 117, ESC 81, 7.2 v batteries 135. Second run same adjustments with two 7 cell ep4500 packs. Motor 129(stock water jacket), ESC 89, batteries 127. all ran with a X642. Much better.

[sdartt]

1. Should the bottom of the strut, speed master, be 1/8 to 1/4 above the bottom of the sponsons or below the deck?

2. Using a speed master 21 rudder. It looks a little long? If it does need to be
shortened how much should it be below the bottom of the sponsons?

I am building two MM, this is the first it has a fei. XL 10 and esc CC 120. I have gutted the radio box and old M-mount. Installed CF from Darin's supplier.

I dont know if I would use the 1512 2d. A 1512 2.5D(2050kv) would be a better choice, or the 1515 1Y also. These 2 choices should do great on a 4s setup. I would also look at the y537/3 prop also.

I would absolutely go with the 1515 1Y... it's a perfect motor for 4S2P, and with the newer cells, would likely work for a sprint setup on 4S1P... Very efficient motor and quite powerful...

[Fluid]

Darin, the 1515/1Y is a great racing motor, but for fast sport running it may be a bit too much for most guys. The 1515/2.5D or 1515/1.5Y would be better for those who want more than two minutes of run time, or who want to spin a prop big enough for a heavier or larger boat. IMO the 1515 series is a better size for 4S than the 1512 unless a gear box is used.

Russ, I have the nitro mount. I cut the front off it but if you want it, its free for the shipping.

If you have there mount, it looks to be about 6 inches to the back side of the mount to the back of the boat, or 7 1/2 inches to the centerish of the motor mounts. This is how it looks to be stock from Aeromarine.

[russ722]
