You CANNOT plug things in backwards and expect it to work!

(Damn it, the entry level to RC is now so low, one would start thinking brains are becoming optional.)


The RX's battery plug shares the same rails as the servo plugs, so make sure the red and black wires are exactly how the servo plugs go in next door too.

A "BEC" RX just means you can input up to 7.2V (or maybe even 8.4V) and the RX has its own voltage regulators to keep things level at 6V internally.

Have not yet seen any RX with fusible links inside before, but this can't be discounted either. Get someone else who at least knows what he's doing around electronics to check it out for you.



Powering up with wrong polarity will usually (instantly!) blow the transistors in your servos first - did you smell any electronics frying? Sometimes the RX survives, if you're lucky.
