Thanks for the welcome!

Well, I got the plane out of the tree, got a repair kit (new wings, props, etc.) and have a new plan. I'm going to make this thing fly.

Seems to me this (and most other) differential thrust planes have a common problem; The motors are too close to the axis of the plane causing sllooowww turns. I've got the thing apart and am going to move the engines farther apart. I'm also going to add 12" or so onto the wings as a polyhedral extension so it will be more of a glider with greater lift and shallow glide slope. I'm hoping that this will stop the need for the "tap" method of flying these planes.

I've also found that Gorilla glue is great stuff for foamies. Strong and dries in 3 hours or so. Foams up when drying but is clear and easily removed from the foam.

So, here's the plan: Remove the plastic frame from the center of the wing, split the wing, move the motor housings outboard by 1.5 inches EACH (3 inches between the motors), add an extension to the center of the wing (so the wing cutouts match the motor housings), add polyhedral extensions to the wings for stability. I'm going to use a mix of hot glue and Gorilla glue for attaching the new parts.

My goal is to get better control for turns, better gliding for power off and longer flight times.
