- developed by T.O.P Racing, Principal Engineer - Josh Cyrul - Chassis Flex Isolation (CFI), Chassis Flex can be adjusted independently in 3 areas, front/rear/centre. - Low Centre of Gracity (CG) - Strong and Super Light Weigh Chassis -
All structural components lay mostly on main chassis to minimise
material and volume mass above the main chassis whilst at the same time
optimising the overall rigity without relying on the upper chassis to
create strength. - Shock Towers are mounted directly on the bulkhead eliminating bulkhead covers and lowering the CG. -
Isotropic and Anisotropic Flex Material (IFM & AFM), the Photon
uses anisotropic flex material for rubber racing and isotropic flex
material for foam racing. This optimises the required directional flex
for both rubber and foam tyre racing. Different chassis materials for
rubber and foam versions are not ofter offered by other manufacturers -
common practice has been to use the same material and simply make it
thicker for higher bite applications!! - Unique LiPo Mounting System (LiPoMS) allows the racer to fine tune the LiPo mounting position without aftermarket LiPo trays. -
LiPoMS provides a unique location which allows racers to balance the
car left and right with minimal total amount of added weight. This
allows the weight required to meet regulations to be placed near the
centre line to make the CG as narrow as possible. Optional brass
balancing weights are available! - Low Friction Light Weight Diff.
Pulleys - Diff Ball slots use unique 3 point triangular pulley slots
(TPS). This minimises weight and friction and at the same time allows
reservoirs for diff. grease to spin out gradually and lubricate the
diff. balls by centrifugal force. - Snap-on Diff. dust covers also serve as air vents and allow air to exhaust when the drive belt presses on the pulley. - Ball Diff. can be adjusted externally. - Ball Diff. tension linearity can be adjusted. - Low Friction, Light Weight, Strengthened, Composite Front Spool with air vents to minimise friction. - Diff. height and belt tension adjustability (19 steps). -
Improved Symmetric Centre Pulley (iSCP) - retained from the Scythe and
ARP, the Photon improves on this concept by allowing the bearing to be
placed in the centre pulley to allow easy maintenance and height
adjustability. - Front and Rear Diff/Spool removal by unfastening just 4 screws! - Centre pulley removal by unfastening just 2 screws! - Motor Mount Geometry accomodates brushless motors and a wider range of spur gears. - Unique Rear Hub/Suspension Design to improve impact resistance. -
Reversible Suspension Arms to allow fine tuning of shock position -
designed with strength, durability, adjustability and performance. -
Suspension Pin Guard avoids excess pressure on suspension pins and set
screws whilst securely locking the suspension pins in place. -
Off-Centre Suspension Mount Inserts allow the racer to adjust
suspension mount height, tread width and toe angles with the least
amount of time and parts. The alloy suspension inserts can be rotated
180deg. to allow further fine tuning. Coupled with 3 different
suspension mounts, the racer has an option of 6 hinge pin height
locations at 0.5mm increments. - Sway Bar link height can be adjusted without removing the sway ball link. -
Controlled Turbulence Shock Piston (CTSP) - In most shocks, it is
difficult to assemble them all with identical rebound. Photon's unique
piston design controls turbulence and maximises the amount of shock oil
to flow through the poston holes instead of around the piston edge
minimising 'blow by'. - Linear Ackerman (LA) - Photon steering crank allows 3 forward/rearward adjustment positions for the steering pivot balls. -
Radial Ackerman (RA) - Photon also allows radial adjustment of the
pivot ball positions by using easily removable inserts. A total of 4
positions are available from 9mm to 12mm apart in 1mm increments.
Linear and Radial ackerman gives a total of 12 steering geometried from
the steering crank alone. It also allows the change of ackerman
without changing the seervo leverage so steering speed and response
stay constant. - 5.3mm Ball Studs and Ball Cups used throughout included threaded ball studs to optimise weight/strength. -
The ball stud and through-hole ball cup design with 3.0mm hex slot
allows easy removal of shocks, steering and camber links without
wearing out tapping holes on plastics and without snapping off ball
cups!! - Larger diameter ball stud and cup result in smoother operating ball/socket joints. - 30mm tie rods throughout reduce the amount of spares needed. - All 4 bulkheads are identical to minimise spare parts. -
All suspension parts including suspension arms, castor blocks,
universals, sterring/rear hubs and shocks are backward compatible with
TOP ARP and CFP cars.
