RE: CG Sky Tiger fans
A6, awesome deal. I built one of these when I was a teenager back in 1986. It was my second plane. I had it for many many years.
A couple of things, you have the original. Also, the original did have a semi-symmetrical wing. It has slight curvature from the spar forward, which will help with inverted flight. If I am not mistaken the updated Tiger had more curvature if not a fully symmetrical airfoil.
Also, the .60 is a perfect engine for it. It is a .60 sized plane. If you need to slow it down, other than using the throttle, go with a larger diameter lower pitch prop. Like a 13-4 or 13-5. If that is too much than maybe a 12-5. Lower pitch will make it easier to land. Do not be afraid to get it slow on landing. The wing has a very gentle stall. Get familiar with the engine and make sure it runs good before flying. And remember that a needle setting that is too rich is just as bad or even worse than being too lean, on the high speed needle. It will just load up with fuel and die.
One interesting note, I learned to fly on the original CG Eagle 63. The Sky Tiger was the same airplane, just built upside down with the wing mounted on the bottom. So essentially, it has the same wing loading as a trainer. Very good idea and a great design. You will love it!
