Default RE: Rio EP stabilization

ORIGINAL: hyrulejedi86

So, I tried the boat again today. I tried a 38mm two blade and it was really slow. It just ran the prop fast but got no push behind it.

I tried the three blade 38mm and it worked quite well however I was using my 3,000 mAh 20C battery and it ended up puffing it a little bit.
Why would it do this if the motor is only a 40A motor and a 60A ESC?

Then along the same motor battery esc combo I have another question:

I am thinking of building another boat this summer and was wondering if the 5000 mAh 20C batteries would work well with the following motor and ESC?

70A motor:

120A ESC:

a couple things..
one boats can pull much amps than what the motor is rated to, second even if a esc is rated at 60Amps it can and will allow much much more than that
the motor you are running is spinnig 40,000rpm unloaded, and that's alot!
how many Mah did you put back into the pack when you charged it?

the motor you listed is not a 540 motor and has way to much KV for any boat
if you want to run 3s choose a motor that is more in the 2500kv to 2900kv range..
