Building the 416 for racing part 6

CHASSIS PARTS

Carbon fibre steering brace. This is custom made to be able to remove the aluminium brace to avoid interference with the upper deck like the aluminium brace do, if you run it disconnected that is normal, at least outdoors. steering brace

   

EXPERIMENTAL UPPER CHASSIS exp upper chassis

 All these carbon parts we received within one week after sending the CAD files to Fibrelyte, pretty impressive! Made from similar stiffness material as the standard Tamiya 416 WE chassis.

The first upper chassis is same as standard but with a cut out at the rear.

The second chassis is shaped in a way to add more flex around front of the motor position area. Both these are experimental parts just to see if their effects can be felt at the track.

ALUMINIUM SPRING RETAINER

These we use because they should keep the springs better aligned in the center of the damper rod. If the spring is not well aligned it might add horisontal forces on the damper rod trying  to ” bend”  it and I belive that can add friction from the damper rod sealings. Trying to remove friction and stiction is one of the main points that full scale racing damper manufacturers focus on in their development work.Damper retainer

 

FLOURINE BALL CONNECTORS

These minimizes the friction from the connecting points for the damper on the damper mount and on the suspension arm.ball connectors

RACE SUSPENSION

We have pre assembled new suspension components that will be used only for the races. We will replace the complete front and rear uprights together with the driveshafts to limit running on these important components. The uprights are built with Square titanium wheel axles, TRF flourine sealed  bearings, aluminium driveshafts front and rear and low friction lubrication for the driveshaft joint. For testing we will use the normal uprights and steel driveshafts but for races we replace them with these complete uprights.

Testing update

The recent high outdoor temparetures was a good opportunity to do some hot weather testing with track surface temperatures reaching 45 degrees.  Most of the testing was done with the same specification of Sweep tyres that are used in the ETS series. We found that the tyres have a very high wear rate which is worrying as only one set of tyres is allowed for qualifying. But we expect the tyre wear will be less at the Andernach track.  The Sweep tyres have a lot less grip than the normal LRP 27. The car is understeering more with Sweep but the grip level is high at Andernach so the balance might still be quite good there with the same set up.03072009111

SQUARE TITANIUM WHEEL AXLES

These are light only 2,3 g / pc. Less than half the weight of the standard axles. Lowering weight this far out of the corners of the car should improve cornering speed and steering due to less polar moment of inertia. Soon to be tested to see if its effect can be felt on the track.
