I assume that the receiver is broadcasting a 2.4 signal so.. Another question. If 12 people are flying (the limit and fills the frequencies) and 3 more turn on, will the broadcasting receivers trying to link with the transmitters cause any interference as the channels are full??

According to posted specs though, 120 people can fly at the same time....

I can't remember why you can have 120 but there was a reason stated way back. If it is truly only 12......that does raise some questions at large events for the lucky #13.

From what I recall on several posts and talks with XPS.....the module does not transmit until it hears from the RX. The RX is the brains of the unit

Kris,

72Mhz is still working great for me too. I hate to see people still putting XPS in the same league as Futaba and JR, it's not.

If 72Mhz is working for you, then indeed stick with it. However, when you decide to consider making the jump, I wouldn't recommend basing your decision on the track record of XPS.

Correction.......JR has yet to produce a 2.4 unit.........They use Spektrum 2.4 in their radios and Spektrum uses JR radios for their casings. But that is splitting hairs really.

I'm also with you......if your scared, unsure or anything else......stick with 72mhz.....you know the risks there. They have not changed in years.

2.4 is full of new risks that cause the same problem as 72mhz.....crashes. I would say you have to look at all the brands across the board for 2.4........(XPS. Spektrum, Futaba, ASSAN) then once you decide 2.4 is for you, look at specific brands that meet your needs/wants/price.
