hadirabie> Take a look at  http://dhrc.rchomepage.com/calcAdvanced.htm for a setup calc. Change the motor pinion value to see the effects on Rotor RPM. Motor pinion is same as gear ratio like a bicycle or car gearing. For a bike compare it to the front gear, bigger is more speed but less torque.

	hey burnaby thats a very nice link. thanks..:) so what i understand. thats for hovering and pretty soft flying , it wont hurt having a bigger number of teeth on the pinion. but in case of 3d , we must have both , head speed and torque.. thanks again for the link

	hadirabie> correct, critical number is the Rotor RPM. There's a min and max range the heli in hover in with the usual tadeoff. Higher mean more performance but less fly time; high quality parts are required for max speed. Align recommends for 600 start with 14t, move to 15t for 3D.
