Ed I've been flying with Spektrum 2.4 ghz DX7 for almost two years now, dont be afraid on using 2.4 ghz technology its awsome fast and you'll forget about frecuencies or tags, just start up your engine and fly like I say " full colors" for me 72 mhz is compared to B/W TV to Color TV is so different added to this is the simplicity off mixes and performance of 21st century radios.

Thanks.
