No special reason BEM, just got too many 36Mhz RX's and I don't want to be unplugging and plugging mudules.

The ONLY thing I worry about is some other pilot powering up on my channel but my club is fairly rural so it's easy to keep an eye on what's happening. I'm the only bloke not on 2.4 at pattern comps but I have the wireless frequency select RX's in my Pattern planes so I can change if there's a clash. I've still got the old "big" 7 channel PCM RX's that came with my 7UAPS 18 years ago that work fine for sport planes.

The 2.4 RX's are lighter (which is a plus) and do the high speed thing with digital servos. If I had to walk into a shop today and start from scratch I wouldn't even consider not going 2.4

I skipped the 9ZAP and jumped to the 14MZ so I'll skip the 18MZ and give it another 6-10 years and see what's out then, I'll probably be 100% 2.4 by then.
