New Chassis Options
Hi guys, next week, we will offer a 2.0mm chassis option for the RSD6.
What can I say.
I have spent some time testing them and I cannot find a quantifiable time difference around the track with either chassis.
Last night for example, the 2.5mm chassis with a flexible top deck ran a fast lap on the same motor and tires of 8.035 seconds. The 2.0mm chassis with a TC6 top deck with the rear brace cut out ran a fast lap of 8.043.
The time splits at 12 laps 24 laps were within .5 seconds every run and time after 6 minutes was always within 2 seconds.
However, the feel is a bit different. The set-ups are identical on both cars.
The 2.0mm chassis feels more forgiving around the track and corners flatter. The car is very easy to drive. It feels like it is less twitchy in turn-in, better mid and milder rotation. Everything happens a tid bit slower with the car.
The 2.5mm chassis is more direct and it rolls more. It pivots a bit better and carves more. It has more turn in and more rotation, and it feels like it switches directions a bit quicker . It is more of a point to point car. Everything happens a tid bit quicker with it.
Now the question you may ask yourself is, which one is better for me?
-Well, this is what I think:
They are tuning options, and they should be used as such. They are both highly adjustable and can be flex tuned when used with different top decks. For example: A 2.5mm chassis with a flexible top deck (like the Zeppin or the soon to be released RSD top deck) and a 2.0 with a stock top deck and all screws flex almost identically. However, the 2.5 can be made stiffer and the 2.0 can be made softer.
The softer chassis can be made to generate more grip with stiffer springs on low traction conditions, such as parking lots and cold weather. The stiffer chassis can take grip away in higher grip conditions such as permanent/prepped asphalt tracks and carpet. The 2.5mm chassis is probably better for big races on carpet when grip is really high.
In the end I think is a matter of preference. If you like a little more responsive car, pick the 2.5mm chassis, if you like a little more stability, pick the 2.0.
