ive seen shins 'latest' car with new chassis for lipo etc (NEW CAR) Its not much different to the current car tbh. i guess you could just buy the chassis when it came out. the motor looked to be in the same postition, but probably moved a few mm. The battery 'tabs' are wider apart to accom lipos.. i just had to shave mine off on the FS.. no big deal.
the best is the new battery posts for lipo.. those look mint
alloy anodized.. ive got pics on my phone i could post. but if your looking to buy the lazer, id buy the current one (FS) and just get the necessary upgrades. ive only just had the FS, i'll probably just get the new chassis and battery posts when they come out, because it looks smart.
the new shell i like too... its high to better accom all the electrics and wiring below. But i guess this is just personal preference.
so bottom line is.. just buy the FS if your looking for a 4-wd car. There isnt much geometry change. You can always buy the optional parts if it really concerns you. Car is mint!
cheers
