VRP GAMECHANGER Pistons w/Patent Pending CFV Technology.
The worlds first Smart Piston for RC...

Rebound System
First VRP started with their XV2 Piston and the Quick Rebound System it features. It was important to keep the exact function of that system because its proven track performance and obvious ease of understanding. The Rebound Valve has been re-designed and updated to be smaller and use less of the inner thickness of the piston to improve durability. This minimization was also needed to fit another ‘system’ into a small part like a piston.

Compression System
This System was designed through hours of research on oil flow and pressures built at the face of the piston from surface tension. VRP made 100’s of iterations refining the technology, which meant hours and hours of programming and machining, countless shock rebuilds, test drops, test jumps, slow motion videos, and ultimately track testing. Over the last 8 months, VRP has refined the invention into a smooth working model that fits what we do in racing. The System is ‘Smart’. It senses shaft speed and reacts as needed with the Patent Pending CFV (Compression Flex Valve) allowing the Piston to have Slow Shaft Speed and High Shaft Speed Compression.

Slow Shaft Speed Compression
At neutral, it is as soft as any shock with a normal set of comparable pistons. On the bench, you will find the suspension is subtle. Its important that this stays in the range of what you run now, it is what makes the suspension soak up bumps and give forward grip as well as a responsive feel at the wheel. So VRP made the ‘Low Shaft Speed’ Compression very similar to what you know.

High Shaft Speed Compression
At High Shaft Speeds like landing a large jump, the CFV will flex and partially cover some of the flow holes and provide additional damping to keep the chassis off the ground. It flexes different amounts depending on the impact and the ‘shaft speed’, so it will respond accordingly. If for example you were to land a smaller jump, the CFV will flex less and provide the correct amount of damping at the time needed. Once the shaft slows down, the valve immediately returns to Slow Shaft Speed Compression, and the damping becomes softer.

Carbon Fiber Compression Flex Valve
Engineered with 20 years of composite experience, the actual Carbon Fiber is made in house at the VRP facility in Houston, Texas, USA. It is unique. From the Carbon itself to the Resin its made with, the properties are designed and tailored for the purpose. They are similar to a reed valve for a musical instrument and care should be taken when handling them. Treated properly, they should last the lifetime of the vehicle.

New Era of Performance
You will never have a buggy land, respond, settle, and be ready for throttle quicker than the Gamechanger Piston. Many jumps and landings become a fluid motion with no chassis scrub or momentum loss. The pistons also make the car more true off the face of every jump because it does not dig in. You will find it easier to manage jumps both taking off and landing like never before. This makes your consistency increase and ultimately your racing success. Where the chassis dug in before and you needed turn marshaled, it won’t and you will continue on.

VRP KYO/XRAY/Tekno 1/8 "Gamechanger" Piston (2) (1.3mm x 6 Hole) (High Pack)
When I first finished building my Tekno SCT410.3 a couple years ago, the first place I ran it was my local track. 2 or 3 weeks prior to finishing the short course, I had got back into the hobby after a few years away by ordering a Tekno ET48.3 and EB48.4, along with Tekin esc/motor combos and Protek 6500mah 4s packs. I had spent several days a week at the track running the two new rigs, and both only needed a couple changes to the base setup to work great on my local track. When I ran the SCT for the first time, also on 4s with a Tekin 1900kv combo, I found that the truck was not performing very well and in the 20 or so minutes that a pack lasts, I had destroyed the brand new body that I had just spent 12 hours painting the night before. I did a bunch of research and ordered pretty much every optional spring and away bar that Tekno offered, both all the regular springs and the low frequency versions, probably a dozen or more full sets, plus I ordered a couple blank sets of the tapered shock pistons to drill out myself. I got every other part I could find that anyone made for the truck if I thought it might help, and then I ordered the set of gamechanger pistons from VRP. One big problem I was having with the truck was it was losing control and flipping on the straights if they were not really smooth, and I thought if the shocks could extend out really quickly and keep the tires in contact with the ground better, but still have the stuff dampening needed to land the jumps I thought it would be a big improvement. As soon as I installed them and made a couple laps I was impressed with how noticeable the change in handling was. It wasn’t totally fixed obviously, but it improved enough that I have since installed gamechagers in 6 or 7 other vehicles with similar results in most of them. They are pricey for some small plastic discs, but I don’t care, if something improves the vehicle I’ll buy it 99% of the time.
