On the Rookie the instructions say that the elevons have to be 3mm up trim if I remember correctly, never had to trim in upright, just a small amount of down elevator needed in inverted flight.

My hotspot requires a good 8mm of up trim to hold in level and reducing it would be very welcome. Wouldn't changing the thrust line cause issues with trimming when increasing / reducing power though?

My Rookie has vectored thrust witch I can trim form the rotary knobs on the top of the Tx, but once set up I have not had to touch it, for all intents and purposes it is parallel with the top of the fus at its neutral position, I also have trim on the canards witch I trim for the changing C of G when using up the fuel, I would try a little reflex on the elevons, what does the manual say?

Mike
Manual says 8mm up trim, and so do all those who own one that I know in person.

It flies neutral at idle and full throttle. It just sucks when inverted (reflex needs to be zeroed out and probably flying reversed needs some reflex as well). Also probably adds some drag. But I do not see changing the incidence of the engine as a solution to this.
