RE: No lift(after long headache) 450 Clone
Do you have a pitch guage?
If so, use it.
Do you have 0 pitch at mid throttle stick? Do you have positive pitch at full throttle?
Also...are you sure you have the rotor blades attached correctly? All of my helis main rotor turns clockwise and the tail rotor (if looking from the "passenger side" or right side of the airframe) turns counter clockwise or turns UP into the wash of the main rotor.
Verify all of the above and if you can do this...I would then look at throttle curve to make sure you have it high enough to turn the main rotor up to a headspeed it will need to take off.
If you do that and still doesnt work...your motor may just be too small for the task or is malfunctioning.
It shouldnt take that much to at least get it to lift off. After it leaves the ground is another story as far as "fine tuning" things. But getting it to leave the ground, all you need is...
1. rotation of main rotor in proper direction
2. positive pitch on main rotor
3. enough headspeed to provide lift
If you have the above...you should get liftoff.
