Andy,
Don't put too much 'faith' in this, I've only heard about them. Having said that, have you seen the 'Spekktrum' spread spectrum radios on 2.4 Ghz? No idea about range but they should definitely 'cure' any glitching. They have some features I think would be just great, no channel worries, dual receivers, and no idea what else. There are two versions, 3 and 6 channels. Not advertised for all types of R/C, and other draw backs. Caught a glimps of one lately, just the advertisements which I tend to take with a grain of salt, and don't know anyone who has one. So, take that for what it's worth...
