hello all,

I am new to RC helis and now own a Hummingbird Electric. The problem is when I throttle up the Heli first vibrates then begins to spin but WILL NOT TAKE OFF. It won't leave the ground one inch.

Also, I start with the throttle stick/right stick in the down position and slowly move it up to gradually increase thrust/rotor speed. But when the stick reaches the half way point or so that it is pointing straight up the engine just stops??!! Is this normal?? How do I adjust this???

not faamiliar with the humming bird but i had a similar problem with a Zagi once. The speed controller in my Zagi had a BEC (battery eliminator circuit), when the volts on the battery get below a certain point it shuts off the drive motor so the reciever can still function. Maybe the battery is weak, or the Speed controller is malfunctioning.

That definitely sounds like it could be the problem. Question: How long should I charge the battery? I charged it for about 1 hour. If it is in fact the speed control then I would have to go to a hobby shop and have them replace it. I bought a RTF chopper because I dont know how or want to build one. Hey..thanks for your help man.

Probably would be a good idea to repost this question in the electric section to be sure the electric guys see it.

Full charge could be in 1 hour if the battery is being charged by a rapid charger, could be 16 hours if it is a trickle charger. the battery should by warm to the touch , but not hot, when it is ready. typically you will only get a 10 minute flight if the battery is fully charged, if it is not fully charged you very well might not get off the ground. it is also important to let the battery cool before using it
