Default Wing and Stab alignment problems!

I have a real dilema.[] My H9 Hell Cat wing measures 3/8" different from tip to tail, and I cannot move the wing over anyfarther. So last night I did the stupid thing, I attached the horizontal tail square with the wing. Now if I measure the tail to the fuse, it is 3/8 off tips to center of firewall. Will I be able to trim this plane out, or should I go in the back yard and cut it up for kindling.

Wow. 3/8ths is a chunk!! Sounds like a vehicle alignment gone horribly wrong. Nonetheless, with the wing and tail now equally crooked, you'll probably need to dial in some rudder trim, and possibly tweak the thrust angle of the engine to get everything except the fuselage tracking in a somewhat straight line.

One thing for sure...the first guy that stops to admire the model? Make him the deal of a lifetime on a low-time warbird.

Don't chop it up though.

One wing tip is forward by 3/8 compared to the other? If that is so then you want to correct that before attempting to fly. I'd say that an 1/8 to 3/16 on a large model is sort of OK but 3/8 will definetly lead to some crabbing in flight issues and probably a slight difference in how it responds to turns to either side.

Oddly enough the stabilizer being skewed isn't as big a deal other than visually and the fact that you'll KNOW that it's that way..
