This is my RCPOWERS Mig29 V1 and the Tomhe Mig29 combination
KF4 3s 2700kv FocalPrice motor 6x3 prop
Pulls hard right on take off still pulls right in flight
Glide test phenomenal even down wind just hangs in the air
Still on glide turn into the wind and plane basically hovers and gently comes down vertically
Now going to change battery to left hand side and try again
But under power pulls right possibly thrust line???
Engine pusher spinning clockwise as viewed from the rear
Any other ideas ?

Check your motor alignment, possibly even shim it just slightly on the right side

If it were torque roll it should pull left as seen from behind.
Have you checked the wings and tail are all square and level to the fuselage?
Wot, no Depron?

Yea going to go back and check everything
It has to be thrust line related climbs hard under power
But never had a profile plane glide like this one
KF's must be absolutely spot on
Might end up activating ailerons and feed a little left bank if I can't trim out completely

Quite possible the motor is out of alignment as Jeff suggested.

Ironically this is the straightest plane I've ever made
Maybe that's the issue

Have you got KF2 or KF4?
KF2 may cause it to climb under power.
Try to take out the pull and climb with the motor angle.

Its my first KF4
Like it so much already converted the BiGMig to KF4
Yea going to give it a little downward angle
Just have to go back to building crooked planes so they fly straight

You could use the spirit level capsule method devised by some clever chap to align the motor more accurately.
