Ok, thanks guys. I'm not too good with programming radios, especially the dx8 that one of the instructors lent me, so I will ask him to help me set the radio, and go from there. There is also a guy with the same airplane as me using flaps, so I will ask him how much elevator mixing he pu in just to get a general idea of where to start from. I will test the flaps high up, to be safe.

Also, I just bought some hitec servos, and realized that they are not ideal, because they have karbonite gears. On hitec's website it sais that they should not be used on gas (not glow) engines. Should I be ok with my glow engine? All of my other servos are not karbonite, so I guess even if one of them failed, I could still hopefully land.
