ratman Posted October 16, 2011 Share Posted October 16, 2011 im looking at buying a thinner chassis plate for my mi4.i currently have the standard 2.5mm chassis but have been looking at getting the 2.0mm soft weave mi4cx version to hopefully give me more front end grip. i race on astro carpet with yello minipins. recon it will work? also anyone know where there is a guide to tuning chassis flex?

Garry Posted October 17, 2011 Share Posted October 17, 2011 It should improve grip all over, not just the front, so basically it'll gain turn-in and stability. General rule of thumb is, the stiffer one end of the car is, the less traction that end of the car will generate. The Xray setup book doesn't go into that much detail about flex: ''Chassis flex (rigidity) is not a readily-available tuning option in typical RC cars. Up until now the nature of chassis technology resulted in a fixed amount of flex being built into each chassis plate and top deck. Therefore racers have always used chassis flex as an unchanging foundation from which they have used all other tuning options to dial in a working setup. Each major change in track and/or tire grip conditions required an entire re-build of their car with either a thicker or thinner chassis. This limitation reduced the ability for drivers to effectively adapt their car’s fundamental setup from week-to-week, or race-to-race. Same day changes that were needed due to significant temperature or weather changes were simply out of the question. With necessity being the mother of invention, the advent of top decks differing in width, mounting points and thickness have become the standard for tuning chassis flex. However, the flex characteristics they provide alone are still inadequate when extreme changes are needed. With XRAY Multi-Flex Technology™ (MFT), drivers can now not only change the amount of overall flex to the extreme, but they are also able to finetune the differing characteristics of both torsional (twisting) and lateral (front to rear) flex. MFT works by simply using, or not using, the rigidity of the aluminum bulkheads between the chassis plate and top deck. For larger changes in flex, screws connecting the bulkheads to the chassis (at strategic locations) are either inserted or removed ; for fine tuning flex, screws mounting the top deck to the bulkheads are either inserted or removed. This provides the ability for the driver to change chassis flex, within minutes, from a stiff setting - resembling today’s common 3mm+ chassis plate and wide/thick top deck (high grip foam racing) - to a flexible setting resembling today’s common 2mm chassis plate with slim/thin top deck (low grip asphalt racing). Utilizing this technology in conjunction with the rest of the T2 innovations from XRAY, drivers can now easily and quickly change the T2’s fundamental setup without ever having to disassemble the chassis/deck/bulkhead and introduce unwanted chassis tweak.''
