That's it, I'm beefing up those wing struts!

Too bad, because that looked like a great working airplane, depended upon by the glider pilots.
Great modification to add the flaps.

That is a HUGE engine for this plane! Did it have a lot of beefing up around the fuse/wing junction. On mine I doubled up the formers at the front and back of the wing saddle and used some tri-stock as well.

Even so, I will take care to fly it very smoothly when doing mild aerobatics.
