it won't be too much ...it won't need the regular wings to fly...
just the two that's mounted to on the engine will do

it'll hang on the prop, you can hover on it all day long
You don't need to go fast to hover.
Just back off of the throttle. Fly it around at 1/2 throttle... i dunno
or use lower pitch props.
well yeah after a while didn't your instructor told you to back off of the throttle on the second half of the loop
to make it look purdier on a .40 to begine with anyway.
Just don't snap it at full throttle or when in a decend.
I have really spent some time and effort making the new wing joint as strong as possible, it looks really good right now. I put three plywood braces in the joint, filled the gap with good, strong balsa and 30 min epoxy, then filled any small gaps with expoy and micro balloons, sanded it down and put a four inch wide strip of thick fiberglass cloth covered with 4 hour epoxy. The wing will hold for sure. That said, I will not be snapping the plane around at full throttle!
IT is fun doing the mods!
