RE: what to do before first flight!?
I will give you how my heli is set up. The only thing that I am going to fool with is the throttle curve. First in the swash type menu set three servos to 120 degrees. THen in the flight menu here are my numbers. Throttle curve normal. Low-0.0%, point 1-40.0%. point 2-55.0%, point 3-inh, and point 4-100.00 stunt 1 low- 100.0%, point 1-inh, point 2-70.0%, point 3-inh, and point 4-100.0%. Swash mix is 3 servos 120 degrees aile--60%, ele-+60%, and pit-+60%. My Trex if flying well and has no tail wag at all. If you need pitch curves or anything else let me know.
