Chris,
Thanks for your post. I now have the Giles flying great!
Some one suggested that i put a 1/8"shim under the BACK of the wing.
THAT is WRONG! Don't do that, you need to drop the front of the wing down about a 1/2 degree, (since my stab was expoxied in already, and i could not change the incidence, without major surgery,breaking the stab loose, that is why i chose dropping the front of the wing) .I did this, and the plane flies great with out adding any trim! (I elongated the dowel holes down about 3/32", then made a new plywood plate, with new dowel holes, and epoxied it behind the existing bulkhead, then filled in the gap on the fuselage, where the wing sets, with epoxy and micro baloons) .
Strange, i was just at another flying site about a half hour ago, and a guy has the same plane sitting there, and you guessed it, the elevator is drooping just sitting there!! He said he has to fly it with all that down trim! That is the FIFTH Giles i have seen with my own eyes, with the exact same problem!
So GREAT PLANEs, Tell me you don't have a problem with incidence!! Speaking of Great Planes, i wrote them a long email, about the wrong upthrust, and wrong incidence, but Kraig, their tech guy never emailed me back!
I don't know why they don't put and addendum in each kit telling modelers, what they need to do, to make it fly right!
That would certainly be better than not saying anything about their problem. What if some poor unsuspecting modeler, that is un aware of the problems, goes out and has an accident with the plane,and possibly hurts someone! Is that the way to address the problem, by NOT ADDRESSING it at all, maybe hoping it will go away by it self????
They flat lied to me when i asked them about the up thrust of more than 2 degrees, they said the plane is designed with it !! I believed them, and on the first flight almost stuck it in the ground , because the plane shot straight up, and almost stalled! Hope this is of some help to you,good flying,and happy landings, Paul
