Again, I didn't build the Pitts.

The control surface hook ups were annoying to potentially unsafe. The elevator linkage especially looked like bad news but as I said, I followed the instructions. The result was bad elevator oscilations at anything approaching half throttle during the maiden.

The issue is they use Z bends on a 50cc gasser. The ailerons and flaps worked ok as did the throttle. The nose steering and elevator not so much. The rudder was pull/pull and that was fine.

I replaced the zbend with all thread and a heavy duty ball link - problem solved. The ailerons have been ok but I'm sure they will wallow out the holes in the servo horn and need to be replaced soon enough, same with the flaps.

The other issue, is they pre-drilled and installed blind nuts for the (very nicely machined) nose wheel strut in the firewall. BUT if you use the engine they recommend, you have to relocate the blind nuts or you wont have enough prop clearance. If you realize this after you install the firewall, your screwed.
