Hello

Have been playing with my new outrunner Axi 2808 motor with 7x7 prop.
Loads of power. Performs great on my Microjet. Could fly faster though.

Unfortunately, with this motor, Microjet seems to suffer from motor torque.
I guess that is the side effects of rotating the entire can casing.

Currently the trim is different at various throttle setting.
Would it help if I mount the motor to give it right thrust?
Would it get rid (or at least reduce) the torque effect?

On a Micro Jet Pusher, it would be left thrust would it not?
Anyway, yes, why not try.
But 1st up why not try using a smaller prop, like a 6 x 3?

Currently the bird veers left during throttling up.
Giving a right thrust would involve rotating the motor mount counter clockwise (looking from top)

I've tried 6x3 before. But I tot it was quite tough to hand-launch it by myself.
Changing to a bigger prop (and outrunner) made it easier.
However, the MicroJet now suffers from the torque effect.

is that the multiplex micro jet? How did you mount the motor.

I would think the rotating mass of the magnets would give a gyroscopic effect ,not a torque effect,this would ,I think cause a turn as you raise or lower the nose ,while trying to maintain a straight course, not quite the same as torque effect.
I remember reading that the ww1 fighters that used rotary engines experienced this effect.theclever pilots used this effect to outturn their opponents in a dogfight
