I have to install the garmin magnetometer, I can install it within 3° of the in flight level cruise attitude, can I use the 90° side longeron to have the right incidence?
I would say yes. The wing should be at (I believe) 1 1/2 degrees positive from the canopy rail, so the canopy rail should be about level in cruise. Is the plane flyable and you could measure it in flight to verify?
