Ok guys, thanks. Shouldn't be much tougher than my Fokker Triplane I don't imagine. I was just wondering if the factory specs on control throws and c.g. were in the ballpark. Without adding weight, mine balances at about 160-165 mm rearward of the top wing center section leading edge. That is a touch rearward of the 150 mm they spec, but well ahead of the cabane. Think it will be alright there? Without doing all the measuring and calculating, it looks to be well forward.....

Just don't want it "snap happy" on the first flight.
