RE: Tribute 4D
I bought the PNP as soon as it came out. The engine flies the plane very well. Hovers nicely and has decent pull out. Not a rocket, though. Use the recommended 11X4 prop. The 12.25X3.75 is a definite step backwards. Put some foam between the tank and the fuse or you'll have serious foaming which puts air bubbles in the fuel line. Definitely replace the clunk fuel line. It's a loose fit and came off on me in flight. I put a 1500mah nimh battery in place of the supplied 600mah nicad and added a charging jack. The on-off switch plate was backwards also. I leave mine assembled because it's kind of awkward feeding the leads in and out of the wing. CG was dead on and lateral balance needed a 1/2 ounce on the left wing tip. Landings are so rock steady you'll get spoiled. One last thing, the tail wheel pulled out of the fuse. I guess they scrimped on the epoxy there.
