Well John, since you seem to be the only one following, I decided after (not) so much deliberation, to pick up a new HO204 from Mike at Kyle USA. I read a few guides here (mainly the build from kwtoxman) and his view on the new vs used seemed pretty rational to me, so I decided to spend a bit more and go new. Granted, my RC is track only (currently), I feel it is a worthy upgrade for both speed and safety. I think my only concern at this point is where to mount the preload adjuster- with the banzai sato's I am going to mount shortly, I am very limited on the location for the preload..any thoughts? I know people tend to put it under the seat, but options are always nice.
