Art-tech Corsair
 

I recently purchased an Art-Tech Corsiar. Unfortunately, it flies terribly. The model constantly pitches up, and consequently, will not fly straight. I have read other posts decribing this model as "flying on rails." Nitro Hobbies sent a replacement elevator set, but this has not helped. Also, Ntro Models tech support sugges that I trim the model by adjusting the length of the control rods, but this does not help. Does anyone have answers?

The way you explain it, in 2 words-tail-heavy !!! Just went through the same thing with another plane.. Rebalance the plane & you should be good to go !!! Good Luck

Like he said.

Check that the C.G. occurs in front of the 25% MAC point on the wings.

You can eyeball this pretty easily.

If the plane stops nosing up, but still feels "pitchy", move the linkage on the elevator servo IN one hole, and then OUT one hole on the elevator itself.
