I wonder, as this is a balsa plane, what it the wing mounting mechanism and how much G's will the plane be able to withstand.
flying it with a 12-14 lbs turbine will get it going at approx 150-160mph, do you think the airframe will be able to sustain a high G loads due to elevator yanking on high speed passes?

Joao - do you have some pictures of the inside of the plane and the wing mounting?
hopefully this airframe will turn out to be a winner and not brake down in mid air...

any thoughts?
