what kv motor for a mini boat ?

[lucozader]

i want a 2040 motor

for a 12 - 15 inch boat

what kv motor ?

[Basstronics]

On 2, 3 or 4S?

That is the deciding factor.

[lucozader]

i have plenty of 2 and 3 cell lipos

which motor lipo combo is best for mini boats.

[Basstronics]

Is it a mono, hydro or cat? That also matters.

I have a micro hydro I have a 3600KV and run on 3S (almost 40K @ the prop). Runs awesome.

Theres not many 2040 motors to choose from.

There's a limited range of props available for min boats too so what sort of run time are you after?

Do you mean 3600kv on 3s for 40,000. Martin.

"Theres not many 2040 motors to choose from." There are a lot of 2040 motors to chose from Ammo, Leapord, Tacon, Tenshock, Feigao, Viper to name a few.

Yes I meant 3600KV.

Post up some links. Ive had a hard time finding many options in the 2040 motors. The KV's seem to be far off whack for what I was aiming for (38,000 RPM).

40,000 RPM seems to be working well for me- for now. And for ref. that is in a micro hydro.

i have decided to get a tenshock viper 4000kv

i am used to 2600kv with 3 cell lipo myself

i will get the 4000kv and run with a 2 cell lipo to see what it is like

thanks guys

You'll have a wide variety of props with that, 27-29 mm if is its submerged drive ECO style, 29-32mm surface drive, should net you 4-6 minutes on a 5-700g boat with 2200mAh.

[lucozader]

will a 35 a esc be ok for this ?

[NativePaul]

At the smaller end of the scale you will be fine at the bigger end you will have to avoid high pitches I run a 40A and ESC and x632 and 1732 are marginal.

[Basstronics]

3600 KV, type o. Corrected now.

It runs good!

I just noticed www.hobbypartz.com is now carrying a NICE selection of the 2040 motors. Many different KV's to choose from!

Very exciting news!

[wakeboardfusion]

Always wondered about these in a mini believe it has a bigger brother at 400 watts too.
Hopefully someone here has more information on suitability
