Jimnie - The ads for the model now say it is for a .60 to a .90. So in that regard I didn't "modify" the model. Although my model could not even begin to balance with a .90. In any case I have taken responsibility for the modifications I made.

However, the CG is in the range suggested by the manufacturer and it still snaps doing gentle turns. A larger engine is not the culprit.

Maybe it's one of the defects in workman ship such as the various flat spots on the front of leading edge of the wing (that fliton built - not me). Or maybe it's some of the undulations and lumps in the wing sheeting that never would have passed muster if I had built the model. Or maybe its the sum of all the building errors and lack of attention to detail in the build that causing the problem. The design itself looks excellent. But it looks like it was built by people who wanted to slap it together as quickly as possible in a factory. There is no attention to detail at all in the build. Up close it's a really ugly build. Joints don't fit that well and there are a multitude of sins in the build

As far as I'm concerned if I really want this plane right then the only way to do it is to begin by removing ALL the covering (which is the worst crap I've ever seen - didn't even know they made covering this bad). Then pull out the sanding blocks and actually sand the structure so that the leading edges around rounded over properly and the wing sheeting is a smooth curve from leading edge to trailing edge. Then fix anything else I will probably find.

After that I can recover it using decent covering and that may fix it and it may not.

Do you honestly believe that if this model weighs 3 oz more than the mfg recommends that it should turn from the jewel they claim it to be to the piece of doggie doo that I have? I could put 3 oz extra weight in an airplane having 200 inches of wing and although it might not climb out as well it wouldn't turn it into a vicious beast.

So anyway, yeah, I'd have much rather built the model from plans so that it would have been built right because I don't see much wrong with the engineering - just the way they built it.
