I have a Vaterra brushless Camaro. The main complaint is that the toe-in, caster and camber are not adjustable out of the box. I have done a lot of mods and I love the car. Mods are:
All metal upgrades available from Vaterra
HPI Flux 2 shocks
3mm x 25mm rods to make toe in adjustable
locked front diff.
HPI Vintage wheels and tires
Replaced front shock mount with a rear mount for more adjustability
Body painted by Indyhobbies
7.4V 50c battery
Handling and speed are GREAT. Faster than my Traxxas Funny car in 132'.
