Hi,

I just read through this thread, and perhaps this is worth spelling out.

Power up your Transmitter first. With the transmitter powered up, then connect the battery to your Electronic Speed Controller.

Then fly, work on the setup, etc.

Then, disconnect the battery from the ESC.

Finally, turn off the transmitter. Always in that order.

Never allow battery power to reach the ESC before the transmitter is turned on. Always disconnect the battery from the ESC before you turn your transmitter off.

People who deviate from that sequence often get bitten.

Best wishes,
Dave Olson
