Thanks for your help guys,

The plastic around the battery connection is fine, no warping or melting everything looks fine. Also tried the Display and nothing.

I tried what you tried Sim, and still nothing.

This is a-feaking-mazing. How does it stop working overight?

Looks like the only option is to miss out on a sh1tload of racing and send it back to Airtronics. I sold my backup M8 only a few months ago because I thought I'd never need to have a spare radio.. How wrong I was

Might upgrade to the M11S and keep this one as a spare for future mysterious failures.

Thanks Again for your Help guys.

Cheers
Stephen
