Hi!
Some news about my plane converted with the 25LA (without solenoid), I flew a few days but the last attempt my wing broke in two parts because of a structural weakness.

The plane frame was ok for repair. So I adapt a Calmato wing and change the engine for a 40FP and reinstall the solenoid.

With this engine the small bubbles like dust that come from the solenoid have no effect on the engine operation.And now I can use the solenoid, and fine-tune the engine operation. So for me the 25LA is too small to work with the solenoid because of its sensitivity to small bubbles.
