just to bash around no racing. parking lots, dirt lots and some small jumps.

is there alot of parts available for both?

which is better?

I want to stay around the 400 mark.

Hyper 7

besides the KPS why woul;dyou go with the 7?

There seems to be a $50.00 difference and if I go with the violator for the 50 bucks more I get the humpack and a few other goodies.

So forget about price it's just based on the .32 vio vs the 7.

The hyper is tough as nails and has tons of hop up parts available you can upgrade right up to pro standard. Spares are cheap, available all over the place and plentiful on ebay. Should you decide to race at a later date it will also be able to manage that with ease.
The Violators not a bad buggy its just the hyper is better all round

i got a hyper7 pbs for sell check out my add on rcu.

how much faster is the vio with the .32 than the RTR hyper 7?

I doubt it would be much faster top speed, though it would likely be faster on acceleration. The hyper comes with 3 different engines so it much depends which one. The hyper 8 port is the fastest and would probably be faster than the .32, the hyper 4 port is a good all rounder and then theres the mach .28 which would be a similar engine to the .32.
Don't be fooled by displacement. Whilst a cheap .32 may be better than a cheap .21, a Race .21 will leave the rest standing because of the smooth power delivery and the fancy porting allowing insane amounts of revs.
Don't end up buying a RTR buggy just on the basis of the engine capacity. If you stay in the hobby for more than a few months you will likely buy a more quality engine anyway and when you do that you will want to bolt it on a quality buggy!
