..and there was that awful smell.
It's an old 40MHz unit and I wonder if the damage is repairable. When trued on, the Rx just makes the servos chatter, randomly.
What would have burned out?
Is it repairable?
Thanks!

Have a look inside and take a photo of where it smells. It is most likely to be a toasted regulator that doesn't have reverse protection.

Thanks, will do.
[/size]It's recently been given to me and when I took it apart three of six screws were missing. Maybe the problem was there before and someone tried. I've a pal who's a wizard with electronic repairs who will look at it for me.[size=78%]

Most would have a reverse polarity protection diode to prevent this from happening. It may be something simple if you can locate the burnt out component(s).
