Sean, thanx 4 the offer (i just might take U up on it someday...) but for now problem solved!!!

i took a hard look again on the problem at hand, and it just hit me that it coud be the hinges poorly alligned causing the control surfaces to warp

the cores are BVM so i new tey were straight before the "expert" glassed them, but the problem wasn't in the glassing, it was the hinging! i cut the hinges and voila! the rudder sprung back, perfectly straight again!

i will have to correct some sanding that was done to correct the warps once the control surfaces were incorectly installed (what an expert![:'(]) but that will not be a big problem

i did the same for the elevators, the same "miracle" was produced... i weighted down all the control surfaces, am sure they will (gladly) go back to their initial shape overnight....

later i will re-hinge all moving surfaces to obtain the desired truness of the trailling edges

Sean thanx again for your help and your patience,
Vasek

P.S. i am sure some other issue will come up (this is my first jet) so i hope to see U on my future posts [sm=drowning.gif]
