Ok, I am going to start to build it soon, so I will figure out as I go along.

BTW, that deadstick landing that took off the LG was when the engine quit 10-12 off the ground in a hover. More of a controlled crash. He too has the bottom of the fuse reinforced as I described. In his case, he has sheeted the entire fuse upto the bay behing the canopy with 1/8" balsa

Anyway, can someone answer the engine question?
