16.5 " JAE rigger

[Doug Smock]

Doug,

You may want to try an x632. It seems to do well in many of the micro models we've run. Otherwise a Y535 cut down to 32mm may be the ticket. Otherwise, I have a Propshop 3214 you could try if you feel inclined. I also have a Tenshock 32x36 steel prop that might be fun to try. The profile features back-cut to unload. Just let me know, I don't mind loaning to you for testing.

If you get it hooked up with those sizes, I have a Tenshock CNC aluminum P/N TSJ-K4834, 34mm, total pitch right at 48mm. That should break into the low 60mph range if it will handle it.

On our Renegades, we run a V935/3 cut down to 32mm. However, with that high of RPM, I don't think it is appropriate at all. That thing would be doing upwards of 75+mph if it hooked up with that prop. Who knows how hot it would get!

Thanks Ben.

A Turnigy Push 60 amp esc should do the trick. Not cheap but you get a great esc for the money and I doubt you will need to cool it. It is designed for an airplane but, the Plush esc's calibrate fine with pistol grip.

Thats the esc I would run if and when I make one of these. I've got that little inrunner already kicking around.

I've run the old Seaking 60A without water cooling on many occasions. That one in particular seems to run fairly cool as long as you're full throttle.

Thanks Ben.

No problem Doug, just let me know.

this looks good. i truly believe you guys are wasting your time with that motor. you need to be using the df400 from the renegade rigger and castle mamba 25a esc. here is a video of my "jae micro" and i think it will walk away from the ones i have seen in this forum (got it from rundog who got it from gman on rcu). and this is on a x427

I believe the point was for an inexpensive build. If we're talking motor options, my Renegade runs on this: http://www.scorpionsystem.com/catalo...22/HK-2208-24/

I've yet to run full throttle because she flies. It's more than plenty on a 3s1p 1300mah 25/40C. Otherwise, Scorpion has a 4400kv version: http://www.scorpionsystem.com/catalo...k22/HK-2221-6/ which would be too much power IMHO. However on 2s1p, you could run a V935/3 if you watched the amps. You would certainly need a 60A ESC and a higher C rating battery such as 30C at 2200mah.

I for one am just glad there's regained interest in these small riggers. They are too much fun at no slouch speeds.

what about this motor on 3s?

That is correct. The point of the exercise is to see how cheaply we can get the average Joe in the pond with a decent reliable setup.
Chuck that boat is screaming but again, Joe will need a bag to put the pieces in after his first run with that setup.

This is going to be a fun summer...

Thanks for the neat thread guys!!

This just came out from HK, you think they will make bigger ones soon? Water cooled outrunner:

Personally, I think that those wires look awful lightweight. If the max is 30A, then you may fry it. It is a step in the right direction. LittleScreamers was supposed to come out with smaller sizes, but I never saw them.

[old guy]

I have a 3800KV Tenshok motor and the ELE 40A esc would this work in this?? to small, to big, just right???
Thanks For the Help

Just right as long as you don't over prop. X632 right at border line, much more you should be careful. The Tenshock motors, believe it or not, are capable of more watts than you think. You'll cook the ESC.

The ESC came with the motor from mini cat it said 40A Waterproof-Water cooled 6 - 18 nimh or 2-5 lithium. so this will not work what would I need a 60 amp for a little boat like that? this is the part of FE I have no clue about

I just happen to know these motors and would recommend that if you're running 3s, that is fairly high RPM with a 3800kv motor. I was merely trying to provide a top limit for this combination without really being careful. Careful would be not running with hopping in the turns, no half throttle running only full throttle, and watching climbouts.

If you ran a 60A ESC, it would run cooler and less concern for components. With a X632 hooked up, neutral strut, she would be flying at upper 50s. Send me a PM if this doesn't make sense.

I'll shoot in a pennies worth here. I have a 3800kv OR motor in my baby rigger that with those sort of revs is limited to 4x props. 427,430 and a 432 for some real heat and less speed.
I run a similar can in my baby cat and that loves the 427 as much as a 430 if not more.
MY take on small hulls is to go for high rpm with a small prop......actually Ben will agree that I do that for some of my bigger hulls too.

I am know to spin 4400 kv motors on 3S

fwiw I would not spin a 632 on anything less than a 36mm dia Inrunner or a well known 28mm dia out-runner.
I prefer to over power and under prop for a kick off and then dig into to the prop box if I want my hulls to smell bad ( most of them do )

These are my opinions based on water time with my hulls.

[Meniscus]

You're right, I am a fan of more RPM and less prop.

Regarding the x632, I do run on many in-runner motors less than 36mm. In fact, I've run that prop on as small as 20mm x 40mm in the case of some of the Tenshock motors, but I wouldn't recommend that to everyone as the Amps could be too much for most motors of that size. On outrunners, I've run a x632 on as small as 400 size. Sometimes though, these outrunners are not designed for the higher amperage. Easy way to tell is to look at the wires. If they're small, then you can bet they'll give way.

I don't see any issue for example, running x632 on a 28mm long can or even short can for that matter. Essentially, it pulls about the same amps as a detongued Y535 that is commonly used for hydros and riggers of this size. That's not saying though that if your setup is running very wet or the prop is cavitating, then you could have a problem.
