this sure is a quick moving thread!
thanks for the feedback yall. it's a very hard decision for me to take right now.
I like the newness of the SD, but I won't race it before november anyway (it's gas season right now), and I'm afraid yokomo will release a bugfixed version before that, in which case I won't forgive myself for buying it in June.
SD parts *should* not be a problem, but TC3 parts will however be available easier... I also checked my parts box, and I still have A-arms, shock towers, diff parts, suspension parts, ballstuds, kingpins, front oneway, etc... all new (last year's unused racing parts stock) for the TC3. That's quite a lot of cash in that parts box, and I'm kind of short of cash for the time being, thus it's a rather sensitive issue...
And finally, one thing I dislike about yokomo is their continuous version updates... there were something like 6 or 7 MR4TC versions in 3-4 years. I'm worried about my car being obsolete in one year, especially if they start with a graphite/plastic parts version that could very well happen early next year for instance. The TC3 only got semi-minors updates and is still going strong. And the current FT TC3 is a top performer right out of the box these days. However I'm kinda worried about the TC3 reaching EOL soon...
A word about resale value and changing brands. I lived and raced in the US for two years not so long ago... I had: YR4M2, IWC SW (x2), HPI Pro2, TC3, Schum Axis (x2).... Cars came in and went away in a few months. Here in Europe it's way harder, prices are steeper (add 50% to 100% to US prices for kits and parts), people tend to stick to their cars longer. It's also a PITA to sell a used car, even from a reputable pilot like me
at a rock-bottom price, which is still kinda high because of the local new price. People just don't buy used stuff, I still don't get why... Oh well.
blah blah blah who cares anyway. I gotta pick one today...
Thanks for the help all who answered
