motor chatters when throttle is advanced
My wife (bless her heart) got me an early fathers day present in the form of a Hobby Lobby F4U electric plane with a 2.4 radio system. Since today was so nice she told me to go ahead and fly it. After got everything put together when I plugged to battery in I got no beeps like I expected and the motor just chatters when throttle is advanced. As I'm new to electrics can anyone get me headed in the right direction?

RE: motor chatters when throttle is advanced
Lots of possibilities for that issue.
First, I would check to be sure that your throttle is set up so that UP is MORE POWER. If it is reversed, the ESC won't arm and might just beep or do nothing at all.
Second check to be sure that your throttle arm is all of the way down when you turn the TX on...and AFTERWARDS..when you plug the plane's battery in.
Third...it might just be a low battery, without enough juice to get things going. One of my planes "chattered" yesterday. It was a loose connection that wouldn't let enough current / voltage flow to the motor.
I'm a newbie, so there may be zillions of other possibilities, too. Rich

make sure the battery is charged, I suppose it is, and if the throttle trim is set to low the esc will not arm.

Try re binding and be sure throttle sub trim is in neutral and throttle in low motor. Also check that the ESC is plugged into throttle on RX.

RE: motor chatters when throttle is advanced
sounds to me like an overloaded motor....does it work ok at the low end of the throttle stick and chatter as it's advanced?...put a smaller prop on it and see what happens... seems odd to me that these lil motors chatter since there are no moving parts touching other than the bearings... but it seems that this is what happens when the motor cant spin the prop and the motor starts to "slip" and once it "slips" then the timing of the control pulses is no longer correct and the motor tries to spin backwards and then it just gives up....ymmv but thats been my limited experience with this phenomenon
