Before 2.4 came into wide spread usage there was enough incidences of loss of connection. Most could be traced to poor battery maintenance or poor installation. I remember ignition interference. Along comes 2.4 and the hue and cry to switch and all your problems will be solved. I wondered if we are only masking problems with the 2.4 systems and at some time they could possibly swamp the system and cause loss of contact. I wondered this because many of the same players who had problems with the 72 Meg stuff were beginning to have problems with the 2.4, a common denominator perhaps.

On the other hand the trainer arfs that are readily available come with a spectrum/jr or futaba radio. I hate to say it but more than what I consider normal of the sectrum/jr have had problems resulting in loss of control. We recommended that everyone switch out the 4 cell packs that came with the systems and use 5 cell. For the most part the problems have been reduced significantly.

At our field we have Futaba, JR, Hitec, Airtronics, Assan, Hobbyking, Multiplex, one XPS conversion I am aware of and unfortunately the only ones having issues seem to be the odd Spectrum/JR and no one can pin point for certain why.
