Exclusive Modellbau Pitts S1 - need help
 

Hello,

Would anyone happen to have the cg for this pitts. It's the old German made ARC by Exclusive Modellbau. I bought it built and had been previously flown. I've flown it a dozen times or so and it has a tendency to really want to pull out of inverted flight. In other words, when inverted it wants to climb. It's a very abrupt pull, not just a bit of a climb. I've never flown something with this tendency. I had thought the incidence of the top wing might be off but was assured the plane came that way from the factory. I added a bit of up thrust on the engine and have not yet gotten it up in the air again to see if this helps. Just wanted to make sure I have the cg spot on. Any help is appreciated.

The specs - 95.5 inch top wing, Brison 6.4 twin and not sure about weight, although pretty light for it's size. Killer smoke system, probably one of the best I have seen. Very nice flying plane except for this one issue.
