Test flew mine yesterday, and it flew VERY well. The ARF needs all hardware ( including pushrods ) and landing gear replaced, but looks real nice and flies great. Mine has a Brodak .40, sweet motor. Any .35-40 should work well.

Was it very difficult to change the internal hardware - leadout lines and bellcrank?  Why did they need changed?  Why did the push rod need changed?

Actually, shouldn't have said ALL hardware. The bellcrank is fine. Leadouts look good also except I don't like them being soldered. The pushrods feel like cheese, very soft metal, just like the spindly landing gear. They use nylon control horns instead of the flap and elevator joiners with integral horns. Both joiners are VERY thin wire.

How do you seal the screws in the top of the fuel tank from leaking? ~^

If you're talking about my pic, there isn't any. The straps are soldered to the tank.  :P

The brackets are a stock Brodak Part. They work very well.

My p-40 flies quite well. Os la46. I did change out all the controls Tom Morris bellcrank with carbon fiber pushrods and ball links. I stripped mine right out of the box and did silkspan and dope.
