Hi Louis,
A thought came to my head. Are you going to use flaps on take off? If you are you need to use a 3 position switch. One position is to be use for flying. If not you are setup to fly. That is set to flap and elevator to zero, so nothing gets activated. It is great to hear you are flying at 80. I have a member in my club that is 85. We have to keep an eye on him. He takes off lands good . Doesn't stay up long 2 or 3 laps. Then lands.
