Thanks for the help. The glitching is happening before or at the speed control - I know as the lights on the Q2 go a bit crazy when the problem happens.

So I think what I'll try in this order is:

1. not use the "hyper reactive mode" (or whatever Sanwa/Airtronics call it),
2. then try the noise suppressor thing (I'll use Much More rather than Yokomo as they are more readily available where I am)
3. I will try the big worlds kit type capacitor

Have you tried a different crystal? even though the lights on you esc go crazy doesnt necacsarily mean that it's the esc thats the issue remember the esc gets it's input data from the reciever. I had a similar issue one time changed everything except the crystals and untimately found out my TX crystal was bad. heres a checklist to try
1) all wires in good shape no cracks or bare wire
2) anteanna wire not chaffed or showing bare wire and not shortened(this can only be done on the spectrum) and not touching anything including chassisespecialy graphite.
3) motor in good shape comm brushes etc
4) try a second shottky or even three i have seen this work before when someone was having glitching woes
5) try a different set of crystals
6) use two layers of 2bl sided tape to secore the reciever and esc
if none of this helps then you may have a faulty esc or reciever.

I had exactly the same problem, I just merely flicked the steering and the ESC would punch forward, then flicker "full brakes". My PT light went REALLY low, and the loop was right at the beginning of the straightaway so it missed laps all the time when I accelerated.

It was always like that, even with a crappy JR or Hitec servo, but I think it really got bad when I replaced the damaged lead with another, but couldn't open up the case, so I just soldered the three wires together with the existing ones.. maybe a bad soldering job, who knows.. but I soldered in-line a 1000uF capacitor, which helped immensely for my TC, then soldered another 3300uF capacitor to an old receiver battery connector for my 1/12th, and I've run without missed laps nor glitches.
