I would like to see it as a class, but would like to be able to do some regulated mods along the way and not restrict it to been out the box.
If Associated plans are to introduce different cars and new parts over time, then these could easily be amended to the rules as and when, wider arms, stealth gearbox etc are released. Again with people like Eaustace having a big interest in the re-re, then we are going to see the emergence of old hop ups being reproduced and again if they are commercially available then these could be amended within in the rules. What I would say is that any introduction to the rules kept within the original RC10's timeline, so no 2.2 wheels for a while
Motors I would say 17.5T or 21.5T which are from a chosen list, otherwise a handout motor if the price is right, if you stay with a one make handout then you would only need to purchase once for the season. ESC's most should be allowed and as long, as they are in blinky mode then they are all pretty similar. If for some reason a certain speedo should gain an advantage over others, then it gets banned from the series. Batteries and servo's I see no problem with what's available, none will give you an a substantial advantage and I would like to see my car go in a straight line
On the subject of going in a straight line, I never found any disadvantage to the kit steering and was using the same set up at national's and RRC up to 1990, as were many other drivers. The only mod I would say is a decent tie rod between servo and steering and a couple of tie rods. The ballraced set up looks good and was more precise, but in those days it was more important to have a decent servo, which we have in abundance nowadays.
A control tyre may be a good idea and perhaps the same for wheels, possibly somebody could do a 2.0" wheel. Don't Schumacher still make the 3x20 & 4x20 full spikes, they would be ideal, although you would need something different for clay.
Anyhow I think if you introduce re-re upgrades as they become commercially available and they fit in with the timeline then it would be good for the class. Would like to see other mods like hacking the chassis up, dyeing parts etc, whose gonna be the first to do a JV holey

I just would like to see the class evolve through time ant not be like the Tamiya on road classes of the early 90's, although controlled it was totally boring.
Whatever is decided I'm all for giving it a go, will take me back to those early days and could be fun

. The other question is, how many cars are going to be out there to race, as I guess a lot of the sales will never see a race track, let alone travel to one.
