The RCV drive shaft works according to the principle of drive shaft used on full scale vehicles. It is specifically miniaturized to be integrated into RC models.
This is the object of the patent N° : FR 12 59048.
The balls driveshaft «RCV» keep velocities in each angular position of driveshaft.
It's an advantageous alternative to "double joint". The very high level of accuracy and durability offers no play and no wear run after run.
The « RCV » balls driveshaft are made with high accuracy from special steel hardened. Combined with high quality ceramic balls (Si3N4 - grade 5 - hardness > 1400 HV) you can keep them for a long time car after car, costly parts stay like new for several years if you respect the preconisation of use (see user's manual). Occasionally you need to change the inner "POM" cage a cheap operation.
A service of maintenance (cage replacement) is offered free of charge (except shipping costs).
The replacement of a shaft (breakage after a crash, ...) is charged 15 €uros excluding tax.
If you are not satisfied by performance of your product, you have 14 days to send back us with complete refund (in accordance with Terms and conditions)
To get a perfect wheel rotation, we introduce a specific wheel system without pin and screw.
RCV balls driveshaft suppresses the disadvantages of double joint :
Narrow ball bearing
With RCV balls driveshaft :
Tire works better
Improve lateral grip
Steering radius shorter & more constant
Increase front reactivity
Increase rear stability
The stability gain of the rear is very appreciable with the new Mid motor chassis
RCV balls driveshaft is the perfect association with active rear system (ARS) :
Less toe-in = More speed limit (with “stock” motor)
Less toe-in in compression = Less braking in curve
Get a car easier to drive !!
