The uniquely designed Flex Controller provides more flex control and multiple option setting.


To expand range of steering without limiting chassis frame flexibility; you can control traction at your own will.


The material ALCOA 7075-T6 is highly resilient and suited for highly stressed structural parts. With rounds of complex manufacturing processing, including hard coating and treatment, our flex controller system will provide you the essential support in any racing events.


This unique flex controller system provides multiple setting options. You can adjust frame flexibility, for corner entries and corner exits, creating more forward driving grip with optimal/remarkable effectiveness.


Integrating various trial-proven features, our flex controller system strengthens chassis pliability. Rigid chassis frames can safely hold the engine in an accurate position and serve as a great prevention against the many common issues caused by frame movements. Now you can enjoy the thrills of racing without worrying about thread damages in gear box, contact fracture, pressing crack and more.

Adjusting your Frame Flex


Our trial-proof Flex Controller, easily addable and removable, can stiffen the chassis or enable it to flex more to work well with various configurations and designs.



The Flex Controller can be added, removed, or adjusted for stiffness. The Flex Controller can be mounted with different combinations to influence chassis flex to help optimize the handling characteristics of a model for variable track conditions. Use Flex Controller to stiffen the chassis, and tighten the handling of the car (makes it tend more toward under-steering).


This Flex Controller system helps you improve the racing performance by ensuring the rear tires stay hooked up longer during corner entry and hook up quicker at corner exit.


The Flex Controller is mounted so that the flat sections can be rotated to achieve different strengths characteristics.


The Flex Controller is made of tenacious carbon fiber, which adds stiffness to the rear of the chassis. The Flex Controller can also be adjusted to any formation between front and rear to achieve varying degrees of rear stiffness. Adding or subtracting stiffness with the Flex Controller, controls how much frame flex is available at the rear of the chassis frame.


Simulations


EVO-Workshop is dedicated to developing products that cater to your needs. In this ongoing process of perfection, we run multiple trials and tests on our products (see graphs below) with the aim of correcting any identifiable product flaws. We also run regular simulations under different conditions to fine-tune our products, elevating their strength and precision to professionalism.


Using the Flex Controller


If a track is slick and the rear tires have a difficult time getting grip, or if the car is over-steering, more rear chassis stiffening is required. Adjust the positioning and number of screws for more stiffness. This prevents the inside rear tire from lifting too easily, and makes it set back down onto the track quicker. This keeps the inside rear tire hooked to the track longer during corner entry and corner exit effectively, creating more forward driving grip. You can fine-tune the amount/degree of under-steering by varying the positioning and number of screws on the Flex Controller.

 

If the chassis is under-steering, remove the screw of the Flex Controller to add more flex to the chassis. This creates a longer duration of inside wheel lift. If this does not completely take care of the under-steering, the chassis can be run with no Flex Controllers installed, which adds more flex to the rear of the chassis.

 

Chassis Flex vs Tire Grip


In a high grip situation, the rear of the RC requires more chassis frame flex. This allows a longer duration of inside rear tire lift, which lets the RC turn without creating under-steering. In general, having a more rigid frame produces more tire grip. Having more frame flex reduces tire grip.


A stiffer frame configuration is used in low grips situations, such as a damp track or rain, a dusty track or a slick pavement that doesn't provide a lot of tire traction, or when hard spec tires are used

Collision Beam That Affect Frame Flex


Collision beam can add rigidity to the chassis frame. If collision beams are mounted tightly to the car, they will add structural stiffness to the frame and reduce frame flex. This type of mount will allow the frame to flex independently of the Engine’s mounting Stand. The recommended gap between collision beam and engine’s mount is 1mm (maximum).


Collision beam may not fit with all engine mounts, you can use sandpaper to burnish the collision beam to fit with the dimensions of your engine mount.
