Quantum Mechanics – TOP Racing Photon

Middle
The front and rear bulkheads mount on a 3 mm thick bidirectional carbon chassis plate. The chassis is milled out underneath the front & rear diff pulleys, the spur gear and the motor to make for more clearance and better cooling. The 2.5 mm thick top deck of the carpet spec car differs from the rubber spec edition a bit as the carpet version has two additional braces.

TOP Racing’s Photon comes, as described earlier, with a very clever LiPo retainer system with a adjustable brace on the right side of the chassis as well as with two, axial sliding, retainer blocks. These are adjustable according to the size of the (hardcase) LiPo pack you wish to use. In case your LiPo packs do not sport lower retaining lugs the inner plastic support of the Photon comes into play. The support braces the LiPo pack to avoid any unwanted play or conflicts with the front belt. To make full use of the outer brace you should invest in TOP Racing’s LiPo Brace Weight, Centre LiPo Weights and Cylindrical LiPo Weight sets. These mount to the already existing mounting holes and help fine tune the balance of the chassis when using lighter LiPo batteries over conventional NiMH cells. The middle layshaft assembly is of a fixed layshaft design with no rotating parts beside the 100T 64dp spur gear and the 20T drive pulleys on the left and right hand side.

Rear
The set-up of the larger bulkheads that house the rear differential is similar to the front one. Small braces connect the layshaft holder and the bulkheads and also make for a very stiff chassis that is needed for carpet racing. The suspension mounts are similar to the ones up front with different plastic mountings and eccentric bushings for even finer adjustments.

The wheel carriers differ from the traditional design found on other cars as the carriers capture the wishbone and not the other way around. The idea is to have a better support of the carrier on the outer pivot for less flex and less play and therefore a more precise rear end.

The front and rear shock towers are cut from 3 mm thick CF and sport six and five different mounting positions respectively to attach the upper part of the oil filled shocks. These come with threaded alloy shock bodies, red anodised upper and lower caps and a single O-ring cartridge. Supplied with the kit are a total of four different two or three hole shock pistons with 1.0 mm or 1.2 mm holes.

Finish
To complete the carpet foam set-up we used a set of Jaco’s Prism Purple and Magenta tyres as well as Parma/PSE’s 190 mm Alfa body shell. Because of the tight timescale we opted to not send the body to one of your airbrush artists but to use a set of XXXMain’s internal graphics sets. We used #R022 Ice supplied by German distributor LRP Electronic. Body and tyres have been supplied by Joachim of Modell Import Xtra. Forward drive was provided by a Team Orion Vortex Race 6.5T brushless motor, a Team Orion Vortex Race Spec speed control and Team Orion’s new 45C 4600mAh Molecular Power LiPo hardcase batteries. To round off the Team Orion package, a VDS 1009 low-profile servo took over the steering duties.
