Right Motor Rating

[Spitfire_310]

Hi, I have a Walkera 60 and I just want to know what's the right match motor Kv rating I should be using if I have a 30 Amps ESC and 15C 2200 mAh Lipo Batt. Does the pinion teeth counts and should match too? What's Kv really mean and what's the mathimatical equation? Can anybody explain to me please. Thanks a lot.

KV also known as RPM/V you can work the equation out but its far easier to use an headspeed calculator http://www.readyheli.com/Online_Head...lator_s/81.htm

for the 60 look at 3500 to 4200 KV motor's - the higher the KV the lower the Torque so I would not go above the 4200 KV

Pinion size need to match the motor - usually headspeed range for 400 class wants to be 2500-2800 but with the hobby people go up to 3000 to offset the lower torque, if you take gear at 140T its about right.

here is a Hobby and 10T pinion that will do http://www.ehirobo.com/shop/product_...oducts_id=4744

I think I have warned you before the 2200mAh 15C battery is pushing it a little if your setup is a little off you could fry a 30A ESC with it.

Hope this helps.......David
