ive come back in to racing after a long break and bought a 410r, it was false economy, you need the alloy wishbone holders i broke the ff one after 3 heats, them alone are 40 quid, and when you consider the big bore shocks are 100 quid the new v3 at 260 looks good value, the new shell with more room is also worth its weight in gold, it is worth buying the front and rear bulk heads as spares too,
so in my humble opinion go for the v3 the old r version is false economy [ i bought a v3 aswell in the end
as regards to choice go for what you want to buy they are all similar same size and dementions with rubber boots at each corner ! ive seen brilliant drivers with 410 b44 tamiya or schumacher
