Nearly 14 months after giving us the first sneak peek of the car, HPI announces that it is getting closer to finally releasing the 2015 Mustang RTR Spec 5! First rumored to be released on the E10 chassis, HPI officially reveals that the new Mustang RTR Spec 5 body will be fitted to the RS4 Sport 3 touring car chassis, which was first introduced last year. The RS4 Sport 3 chassis features a completely sealed and highly efficient shaft drivetrain with no exposed gears, belts or drivetrain parts to get stuck with rocks or dirt. This version comes fitted with a set of green HRE Tech 7 wheels wrapped in high performance treaded tires.
The HPI 2015 Mustang RTR Spec 5 is powered by the HPI Firebolt 15 turn brushed motor which is controlled by a waterproof HPI speed controller for reliable and trustworthy operation. An enclosed box houses the 2.4GHz radio receiver, ensuring that you have constant control through the HPI pistol-grip steering wheel transmitter.
The drivetrain of all the RS4 Sport 3 models features the motor mounted longitudinally in the molded chassis, next to the long driveshaft that goes down the center of the car. Bevel gear diffs at each end of the car transfer power from the driveshaft to the dogbones and axles that drive each wheel. The entire drivetrain, including the pinion and spur gears, central driveshaft and gear diffs, is completely sealed to protect the drivetrain from rocks and debris. The battery box is large enough to fit any standard battery size, even NiMH 7-cell batteries, held in place by a large hook-and-loop strap, and you can move the battery position for more traction or steering.
The suspension of the RS4 Sport 3 uses the same race-proven double-wishbone suspension and coilover style oil-filled shock absorbers setup that real racing cars use, so not only does it look realistic and cool, it’s also instantly familiar for racers to get used to. Tuning the suspension is made possible with alternate shock mounting locations, and many options such as springs, aluminum shocks and carbon fiber shock towers will be available for anyone wanting to make this into a formidable club racer.
