Greetings. Purchased a SM A10 last year at Florida jets from an individual and now finally getting around to going through it and checking everything out. If anyone is still on this thread could you please let me know how to set the flaps for takeoff and landing . The instructions do not state where the measurements are taken from. [admittedly have not read through the entire thread] Also another question I have is that several people have modified the turbines so that the thrust is slightly upward. Is this an essential modification [mine has not been modified] and is there a reference to how to do that in this thread? Your help would be greatly appreciated. Paul
