Hi Thanks for the reply,

Yes thats right 35mhz is air

Thats strange then how can they get away with flying on 27mhz when that's a ground band. hmmm

I've fallen behind with the transmitters these days, whether they are digital/analog etc. The aerobird extreme is a larger version of the commander so I may go for that. I'll drop in a 27mhx x-tal into my radio and see if I get anything sensible out of it anyway

Thanks again
Andy
