Hi Don. I'm really sorry to hear about the accident.[] As an old C/L flier this is the aspect of R/C that scares the hell out of me. Loosing control and watching your plane self destruct has to be a terrible feeling. Thank God it wasn't your Snipe.
I check the RX voltage with a meter before each flight. My TX displays it's voltage. You can get a meter for about $15 at your hardware store. You might also consider a small set of wind chimes, just to chase away any demons that happen to be hanging around
