I'm a newbie in RC field..I am planning to construct my first Tricopter ever. Can anyone help me to find the power rating to select the motor for a tricopter?

I am at the beginning stage of construction. Arm length of frame: 50cm each. I need a thrust of about 2Kg -- nearly 666 gms for each motor.

  • Welcome! That, surely will depend on a number of design criteria, which you haven't mentioned - weight, size, power-source etc. Could you elaborate teh question, please? – Andrew Aug 30 '14 at 17:33

This depends on what you want to do with your copter.

Hovering: 100-150 Watt/kg
ScaleFlight: 200-300 Watt/kg
Some chilling acrobatic flight: 350-400 Watt/kg
3D acrobatics 500+ Watt/kg
Hardcore 3D 1000 Watt/kg

Just take the real weight of your copter, calculate the total power and divide it by 3 (in your case)

I also have a source for this but i know only a German one: http://www.heli-planet.de/index.php?section=auslegung_von_e_motoren
