Bought one to a Spitfire MK 21 that had contra rotating propps. 700gram weight and fly wery well with no torque. With the 8 propps that included the motor gets WERY hot and 7 propps dont fit in the rear mount so you cant use them.

But the second flight i noticed that the enginge was loose. It was the mount that had cracked in a weak point so the quality on them is not so good and you cant build your own mount eihter. Also make sure the propellers is well balanced.
