Hello gang, new to electric foamys, (suppo motor, 18 esc, 3c 500mah bat) works fine on the bench! ( same setup with 2c500mah bat) no throttle? Battery was charged and works control surfaces but no throttle? Boggles my mind! Try another 2c 500mah bat same thing, no throttle? But 3c 500mah bat works fine? What the heck am I doing wrong?
