There is talk here that 2.4 has more latency than 72mhz FM. That makes sense to me, and the quicker "feel" could be explained by any number of things such as placebo effect (unlikely, I trust you guys  ), but one thing I noticed when I flew a friend's 2.4 airplane was when I put the sticks at extreme positions (on the ground) and let them spring back to neutral, the surfaces would jitter in time with the sticks. This was with standard servos on a DX-7.I don't think that this is a symptom of reduced latency (because if there was a lot of latency, the surfaces would simply jitter at a phase shift) but maybe higher bandwidth? In any case, the plane was a Telemaster, so I couldn't tell any difference in the air. However, I did fly a 2.6 C-ARF Yak on Spektrum, and couldn't tell much of a difference (although it was the first time I'd flown that plane, so I didn't really have a benchmark), but the owner had dialed in a lot of expo. Also, with Bergs, how much latency are we talking about here? I had a tricky time getting used to flying my 3Delight with one, but just figured it was a result of the plane being so small and me being used to larger stuff. I had trouble staying on top of it in a torque roll. But I also didn't have a benchmark for that, either.

Very interesting. I was really excited about XPS when the hype was going, but just couldn't justify spending the $ to get a setup. Plus I either fly at home with no-one around - or our field has about 12 members and pretty much never over 3 planes up at once (usually just one up at a time.) I'm still a bit nervous about my 30% getting shot down by someone on accident. A friend just got a "Raptor G2" electric helicopter. It's on 72, but has no channel number specified... just has 72.790 if I remember right on the back. That makes it that much harder for a new person to realize who he might be shooting down! |
