View Full Version : no throttle?

04-08-2010, 01:22 PM
:(I went to test my heli after days of adjusting and my motor does not appear to be working. I checked throttle hold switch and its off. Any other possibilities?

Plug a servo into the receiver's throttle channel and see what it does. If it doesn't move, there's something wrong with your radio programming. If it does, then look at the ESC. I assume that your servos are all working fine? It's just the throttle? I'll also assume that your motor is plugged into the ESC?

All I get when I raise the throttle stick is 3 servos moving up the swash plate(which is correct) except there is no motor sounds or blades spinning. Where in the programming would I look for an error? Keep in mind Im really new at large heli's so there is a wealth of dumb questions I may ask. Thanks.

Did you plug a servo into the throttle channel yet to see if it moves?

Is your throttle control stick all the way to zero when you connect power( battery) to the ESC. Most ESCs have a safety mode that will not allow them to initialize if the throttle is not a zero when power is connected. Check your throttle curve o make sure you have dead low stick giving you zero throttle.

I did, and I got the servo to move. Also I plugged the speed control into the servo empty servo channel just for a power source, and the rotor came alive when I moved the appropriate stick. By the way when I have all the plugs in correctly and have the transmitter on I get a lot of random beeping from the speed control. Any suggestions? Thanks a lot for the help.

Checked it, and the stick is in the dead low position. I think its the speed control.

Thanks, I did but that wasn't it.

Checked the throttle curve which I haven't gotten to yet in the setup, but this is what it says
NORM says "pos 3"
HOLD 50.0%

Then when I scroll to HOLD it changes to 4.0%
