Wanna make Miss Geigo FAST...need some input

[Flying Scotsman]

Another thing you should think off, is that the boat you are running is an RTR hull and designed for a specific speed threshould.

Stick with the 4074 2200kv on 4s, Only mentioned 6s because it was raised in thread. Martin.

the OP said he wanted to use 6s, that is why i said something about 6s.

I think you will be happy with the 4074 2000 kv on 4s. I have a ul1 2030 kv with an m445 and wouldn't want to go much faster. I would think the leopard would be a more powerful and efficient motor then mine, so you could prop up i'd imagine.

I didn't catch the 3000 mah batts. You will be getting 2 min of run time give or take.

With those batts i'd stay with the stock motor on 6 s with the t 180. 1500 x 22.2 = 33300. With an x437/3 or a x440/3 you will be flyin. As i said before i dont know squat about 6s set ups though so i could be way off on prop size, those should be relatively conservative though.


I think the 4082 might be a little much for MG as well. I have a 3656 size can and she is a hand full on that.

you guys are awesome and this info has helped a ton...off to work and then home to order motor...gonna go with the 2200kv on 5000mah 4S...

I have this motor in my mg with a 150a esc and only running a x642 offset rudder and on 2s 40c 5000mah lipos and it keeps up if not a tad faster than my buddies 6s spartan. I am gonna push the limit though and try it on 5s against everyones advice. I did however buy a backup seaking 180a esc for if and when my esc goes. If you don't want to throw away your money definetly stick to 4s or buy a lower kv motor like a 1500kv or at most the 1774kv jmo

[TheBoatbojo]

Would the 3660SL 3060KV motor be a good option if it were run on 2s or 3s? Also, what is the main difference in using a low Kv motor on 4s comp with a high Kv motor in 2s?

[jac4412]

High kv=more speed, less "pushing" power. You should really stay away from kv that high in this boat... It's going to be working very hard to get speed. I'd say its a 4s minimum boat.

so ur saying I should stay with 2 2S packs??? or will a 2000kv motor with the 180 do great with 2 3S? thanks

and can I expect any gain from just adding the 180 and leaving the stock motor

I ran a tacon 4074 2000kv on 6s with an octura x642 and it screamed hit my highest speed of 63.4mph but my run times were about 3mins with a set of gens ace 5300mah 30c temps were only105 it was fun but not long enough run times. The leopard 2000kv is rated at 25vlts so 5s shouldn't be a problem but that's jmo. I love high rpms but that's also living on the dangerous side and pretty muc asking for something to break. But atleast ill have fun doing it

I got a dumb question, but I noticed the lepord motors don't have cooling jackets, Do they need them? or do I just use the stock MG cooling jacket off the stock motor?
Thanks

[ericwpg]

Lepard moters have matching cooling cans sold seprately and my 4082 runs cold so they are worth every penny

[ron1950]

aquacraft ul-1 motors do very well also and cheep

[benjijames]

I also want to modify the boat set up to get more speed but don't want to spend too much money. I want to buy the seaking 180A esc and a leopard motor 4074 2150 kv or 2200 kv. Will it be possible to run 5S with that setup ? Can I keep the stock motor mount or do I need to buy a new one ? What are the matching cooling cans for leopard motor ? Thanks for your help.

No don't run 5s on either of those motors. Stick to 4s with them.

[ron1950]

if u are tight on cash use the t 180 and the stock motor on 4s .....prop it with a m445......5.5 bullet conectors all around and u will get into the low to mid 40's......u will have to dremal the cornor of the strut bracket but thats about 5 min work.......

A miss Geico with a 4082 a t180 using the internal bec 6s 5000ma 40c and the pro boat radio with a 42 x 55 Grim Racer prop has pulled 50 runs or so with no problems other than blowing the blades off the original props,and eating a strut and flex shaft. To get rid of the bounce i cut the original strut slot a little lower with a dremel and raised the prop. I also glued a big flat catfish weight to the nose and put some fiberglass to make the front wing stiffer. The Boat is a bullet just stop pulling the trigger 20 feet from shore or your gonna make a hole in whatever you hit.

Nice.... Those leopards do run good but I love my cc 1518 I run it on 6s without any problems I'm over the 33000 rpm mark but just under 40000 and run consistent 60's I know I'd be safer running 5s but when compared to 1600kv motors on 6s it's really not a whole lot more. I'll keep rolling the dice for now
