Default RE: Seagull PC-9 120 size...

Hi All,
I have been assembling the PC9. It goes togrther very nicely.

I am however worried about the stall reports mentioned here and there on this thread. At 11lbs. the wing loading is 32lbs./sq.ft. This is high but not excessive. ( my ESM Spitfire is higher and so too was my Platt P51.with no sign of tipstall even when deadstick.)

I think the problem may be the lack of washout in the wing outer panels. A tappered wing without washout and with substantial wing loading is asking for tip stall !!

For those of you that have had the misfortune of stalling this model, could you describe the circumstances more ?. Did it tip stall immediately after going deadstick. ? Or later ? Did you try pushing the nose down to keep the speed up ?

I am thinking of doing some simplewing surgery to produce washout and would like to gather as much info on this problem as I can.

Many thanks,
Cheers
