CentraFlex 1.6mm Carbon Topdeck for Awesomatix A800MMX/A800R

Introducing our brand new one piece CentraFlex 1.6mm Topdeck for the Awesomatix A800MMX! 


  • Centrally distributed flex with several options to move flex point forwards or backwards for different balance
  • Easy overall flex tuning without requiring removal of topdeck to bulkhead mounting screws 
  • Easy removal of spur gear
  • Increased clearance to pinion gear enabling you to use all sizes and combinations without restriction
  • Designed and tested in several platforms with great success
  • Designed and manufactured in Australia 

A single sided topdeck design provides a brilliant option in moving our technology forward. Conventionally in Mid Motor setups, the front of the topdeck is entirely split, just like on the One Piece A800MMX Topdeck, in order to be able to slide the topdeck over the front belt. This provides a significant amount of flex to the front of the car only, creating quite an imbalance in the topdecks flex characteristics.

The CentraFlex has been developed to slide in from the side under the belts, and due to the single sided design, can be joined in front of the spur gear to prevent excessive front topdeck and bulkhead flex, bringing back the balance of front to rear flex provided by the topdeck. We have also been able to significantly increase the clearance to Pinion Gear, making you now able to run any combination you can think of! This design also makes it very easy to change the spur gear.

By installing or removing the ST019 Topdeck Motormount Screws either side of the spur gear, we can change the flex point of the car instantly, either moving it forwards or backwards to adjust the balance of the car. 

As well as this tuning option, we also have braces which can be cut on the topdeck to even further alter the flex characteristics, by changing the flex between the bulkheads, and also moving the flex closer to the bulkheads.

This provides a lot of option in not only adjusting the flex point of the car, but also the overall flex. Combined with the options provided under the chassis by the motor-mount, it can be a very powerful tuning option in getting the absolute most out of your car. 

The best part - all of this translates on the track! All of our testing so far by ourselves and our team drivers has proven this topdeck design to be the pick of the bunch. It offers an incredibly smooth driving feeling, coupled with increased mid-exit corner and high speed steering over the original topdeck. It is very adaptable to all different kinds of tracks, with the inserting and removal of bearings, and also cutting braces making substantial differences in the feeling and balance of the car.

Initially an asymmetrical design would have been thought not to provide symmetrical flex, but in fact the flex is incredibly balanced. To test the theory we even made a "flippable" topdeck and tried brace left and brace right configurations to see if we could feel the difference. It felt 100% identical with laptime reflecting this. That's how we knew that this was going to be the way forward!

We strongly believe this layout proves an advancement in the flex technology of Mid Motor cars and hope that you will have the same experience with your CentraFlex Topdeck for your A800 MMX!

Available in both 1.6mm and 2mm versions. We suggest 1.6mm for use with Aluminium Chassis, and 2mm with Carbon Chassis.
