My thing is tanks obviously and forgive me for butting in. I have experienced fidgety servos and erratic behaviour in my first tank. The culprit was me not reading the instructions for the ESC. If i had read the instructions i would have known that the reciever did not need its own power supply. The ESC provided the power!! I had plugged in the battery pack for the reciever and it was also reciving power from the ESC. TOOMUCH POWER!! Silly tank would do stuff all on its own LOL
.Anyway....as soon as the seperate bat pack for the reciever was unplugged normal service was resumed.
