Thank you guys for your input.

Very Helpful.

Checking for the ballooning effect by using the 45 degree dive is a great and smart approach to settle this problem.
If my estimates and Dave's are not correct with respect to the engine thrust line, then this maneuver should show that since the speed of the plane will increase without adding engine thrust.

As for over powering the plane, I don't know about that. If it is overpowered, how come I can't go straight up? I thought by having an overpowered plane, i will be able to go straight up. It will go but for a short distance until it looses its momentum and then stalls.

I was thinking of building an incidence angle but i don't think i have the time and i will keep on putting it off with out really measuring the angles of the plane. Any suggestions of what to buy with a reasonable price?

Thank you again guys ..... and be patient for my next flight. I am in Maine, and here the season is really hard for flying during the winter. I was lucky to fly last weekend.
