Speed 400 tailplane stresses?
Dug this plane out of mothballs a couple weeks ago and will be upgrading to brushless. Beginning to get curious as to how much stress is imparted on the horizontal tail surfaces which are only Monokoted 3/32" balsa (12" width) and whether it should be a concern? With a 10.5% airfoil she's not likely to be a real speedster but I'd rather beef up the stab than rebuild after a failure.

Thanks, I'll give it a go.
A bit of musing --- For some reason my thinking is there really are minimal forces being placed in the rear horizontals. To me seems the stabilizer simply cuts through the air with the only stresses placed on it coming from the elevator while in deflection, which shouldn't be all that great at this size and speeds.
