Quadrocopter engines

The four brushless engines

The Tiger Motors MT2216 800 kv Coptermotors

Last week I received the four brushless engines for my quadrocopter project from rcflight.se. The MT2216 from Tiger Motors seemed to be quite good for this project with its high performance and still reasonable price. I plan to run them on a three cell LiPo battery with ten inch propellers. That’ll give them 960g of thrust each, almost 4kg of lift in total. So I set a goal of max 2kg total weight of the copter. I think that’ll make it quite maneuverable.

Btw, why do the engine manufacturer specify thrust in g instead of Nm?
