The climbing under power and dropping when the power is chopped is a common trait to most high wings. You can fix a lot of it by using Rodney' directions. To really fix it, move up to a low wing tail drager like the 4* series.

I fought the problem as long as I had my trainer. Near the end of it's life, I was flying with a stack of four popscle sticks under the trailing edge of the wing. That helpped a bit, but the problem was still there.

After the fatal crash of the trainer, I made a stick fuselage and put the patched up trainer wings on it along with the tail section from the trainer. I extended the nose by 2" and the tail 1 1/2' from the format of the trainer. I also addes a 1/2" in cord to the elevator. And made it a tail drager. I went through two of these planes before setteling into the 4*60. Each plane flys differntly. Looking back, I think that the modified trainer I had for my second plane would have been an excelent first plane. Still lots of dyhedrial to keep it stable, and the longer movements of the fuselage gave me a very stable plane. It was easier to land than the trainer and overall it just flew beter. Aerodynamic balance is as important as weight balance.

Basicly though until you get ready to solo and move up in planes, you trainer, even with a couple bad habbits, is best. Remember that learning how to get of trouble is as important in keeping out of trouble. Both are good skills to accuire.
