Another tell me what car I have
Okay, here I have an HPI chassis, I am just not sure what it is. I have looked numbers times on HPI sections of forums, and even Google images, but have had no luck. It is graphite/carbon chassis/shock towers. sway bars etc. Any insight or info on the car would be great. Also could I put a brushless setup in it? I picked it up cheap, and will give me something to do this winter. Thanks in advance!!

Looks to me like an RS4 Pro, could be wrong but its my best educated guess

You can download the manual many of the HPI kits directly from HPI from their website (http://www.hpiracing.com/instructions/). I would suggest downloading both the RS/4 Sport and Pro manuals.
The HPI Sport/Pro kits share many parts, but the steering racks are slightly different. Also the PRO kit came with many of the upgrade parts. Both kits can be configured to use a stick pack or saddle pack. I should also mention that those kits share many parts with older HPI nitro cars, so it shouldn't be too difficult to find replacement parts.
One other thing, the Sport/Pro can also be configured as a 190mm or 200mm car. You would use the same a-arms but different dog bones or CVDs - the part numbers will be in the manuals.
One last item, these cars where designed to run brushed motors - which are a small diameter. You may have issues of the rear belt rubbing on a brushless motor when installed. If your car didn't come with a rear belt tensioner, this can help with the belt rub in the rear. Brushless motors also use smaller spurs/larger pinions, which should help with that issue as well. The real issue on these cars is that you adjust the motor up/down for gear mesh.
Hope this info helps.

Indy, Thanks so much for that link! This is my first REAL on-road. I did realize these were designed with brushed motors. Usually 540 sized correct? I will probably drop a VXL-3s from a previous TRX truck in it, which should be smaller, or close to the same size as most brushed motors. So hopefully I wont run into any rubbing issues. It has a rear belt but I will probably replace that along with both diffs, the front seems to wobble a bit anyway. What sort of gearing should I start with. I dont have a spur or pinion for this car. And Is 32p gearing used?
