- One of our club members here had one and he had a lot of
- trouble with it. He flew it 4 or 5 times that I know of and it crashed
- every time. I think the problem was excess weight. The plane seemed to
- tip stall and roll on its back whenever it got too slow (which was in
- fact not slow at all!) It was powered by an ASP 60 and had air
- operated retracts. I looked pretty good, but didn't fly well at all.
- By the way, this guy is a very good pilot, but he may build heavy.
-
- If I were you, I might think about building the plane without
- retracts to save weight. All of the War Bird models are very sensitive
- to excess weight, some more than others. I had a Top Flight Corsair
- that would snap roll in the blink of an eye if you let it get too
- slow. It also had retracts and 16 oz of lead in the nose to make the
- CG come out right.
-
- I have used the Goldberg retracts, and I don't really
- like them. I have the Dave Brown retraces in my GP Mustang and they
- seem to work better.
