Just completed a built of the Dynam Spitfire (1200mm). All control sufaces work fine, however, giving throttle only results in the engine chattering back and forth. Any ideas? Just a bad ESC? Any testing recommendations?

hi, I had the same problem while building a concorde twin, when I soldered my connections, appaarentely had a bad connection on one motor, did exactly what yours is doing, just chattered back and forth, check your connections carefully, I think you'll find a bad one somewhere, after I made a good connection, motor ran perfectly, hope this helped, like seeing success and happy flying

Thanksfor the guidance. I did remove the engine and found that one of the wires from the ESC was indeed disconnected. I reconnected it and everything works great. Thanks.

set your timing to low. I had the same thing with the waco. I used the program card to make it easy--no beeps to listen for.
