84315 TRF511 Chassis Upgrade Set

This parts set is designed for the TRF511 Chassis and includes a wide range of race-spec Option Parts to further improve its performance potential. The new carbon lower deck and aluminum rear suspension mounts enable the chassis to be compatible with square-shaped battery packs. The new aluminum motor mount shifts the motor position towards the center of the chassis. In addition, the use of 39T pulleys results in an optimum secondary gear reduction ratio.

I found that I could simply add 4x1mm spacers for the front aluminium brace and file down the plastic bumper rather than trimming the aluminium bit itself.

I'd mention again that I think Mr. Tamiya should have included adapted parts for us to use rather than making us trim existing ones.

I'm not sure of the benefits of the thinner chassis, it seems to serve no purpose as it in itself doesn't really affect the centre of mass but does expose a little more.

But I am convinced the belt swap allowing the motor to be moved inboard will be a big improvement, especially for those with short motor shafts as I have - now the mesh is much more confidence inspiring.

But the front belt will surely rub on the servo stay now... shame:
