RC Helicopter Tx setting (Throttle and Pitch Curve)?

Discuss the Align T-Rex 450, 500 and 600 here.

I have a seven point programmable tx. What is the ideal throttle and pitch curve for a newbie pilot like me. I have a Trex 450SE v2 and would like to excel in hovering first and quite inclined towards precision flying (F3C competition)

all i know is that rc helicopters are the hardest thing to fly. i hope yours wasnt expensive because you will crash it while learning. i learned it the hard way, i drove a 250 dollar rc motor truck into a brick wall doing 30 mph and a rc plane into the ground doin60 to 80 mph

ooo I was thinking about getting the Trex... but then I got the Blade CP Pro. I would HIGHLY suggest getting the training gears for your helicopter, cause I will be sure you will chip the blades within seconds of take off. I never had a problem cause I learned fast suprisingly... but my friend... ugh... now I need new blades and a main shaft... anyways, you should have some past experience flying RC Helicopters or I will guarantee you this will be dead on the ground really soon. Make sure that the blades are properly pitched. Now eye down the length of each blade comparing the bottom of the flat-bottom blade to the top of the Paddle Control Frame. They should be parallel to one another. If you are using symmetrical blades use the blade centerline for comparison. The blades should be in pitch always, or the helicopter will not fly or vibrate. Now, I cant tell you how much throttle to use. All I could say is about 2-3 clicks above the half. Just slowly push the throttle up till the helicopter lifts. If the helicopter is lifting too high, then lower it. This is all basic, you should know that. If you haven't flown helicopters before, I would suggest you get a simulator or practic by purchasing a cheaper helicopter, maybe one with Coaxial blades?

Just take it REALLY slow. Trying it out on a sim first would really help you get a feel for it before risking the real thing. And make sure you're pretty far back for those first many flights - you'll want that cushion of space!

Just a linear line going diagonal. Remember algebra? y = x. The curves control how the heli responds to your transmitter. Set the servos and aileron low, have curves at y = x, and you are ready for takeoff!

Check out John salt's web page regarding the Blade 400. it is: http://www.rchelicopterfun.com/blade-400.html. I learned a lot about helicopters from all of his heli pages. His page above links to one of his e-books, which deals with setting up the Blade 400 for a novice, including the perfect throttle and pitch curves (using the Spektrum DX6 transmitter). You'll learn a lot from the site. Good Luck Art M.
