RE: homemade push/pull will it work
It should work, if it's not too heavy.
Keeping both motors running will be a problem.
With any luck at all it'll fly on either alone.
My push-pull Kadet at 13 pounds flies with two OS 40FPs.. on either or both.
The rear motor usually quits first.
I photo'd this this morning.. rear engine failed on takeoff.. the plane can fly on one, but the pilot didn't handle the situation properly..
Did a left turn after getting airborne, but failed to stop the turn when aimed back at the runway.
Too much elevator stalled it, and the right aileron command tipstalled it.
