RE: engine starts backwards
Yup. I first saw an experienced builder / flyer do that years ago. I was watching him prime the engine, after which he attached the glow starter. Then he held the prop backwards against compression for maybe 10 seconds, rotated a half turn in the direction of rotation, and then he grabbed the spinner. In what looked like a nonchalant backwards filp, he snapped the prop backwards with the spinner and the engine fired and started in the proper direction.
Took me about two tries to decide I could do that. I do roughly the same now with my Moki 1.80 - but I use a length of half inch plastic water pipe to push the big prop backwards against compression.
Use the feature to your advantage!
