i dont get it...can some one explane it to me?


..if you want to zero the "UP TRIM" on the elevons , you need to get it from "UP THRUST " from your engine .

On your photo you show "DOWN THRUST" and you should require more "up trim " to correct it.

Have you fly with this set up?


Mine does not "pull up" and flies level with UP TRIM when there is no help from the engine thrust ( on landings = airspeed faster that turbine gasses up thrust )

Even if you have correct "UP THRUST" on your engine (your exhaust should look up=the opposite of your photo below) you should dive when you fly idle=no help from engine...
