RC Race Prep ZooRacing anti-tuck arms & wing mounts
UK based brand RC Race Prep have announced the release of their new anti-tuck arms and adjustable wing mounts for the ZooRacing range of touring car body shells. Starting with the anti-tuck arms, the aim of this design is to decrease the chance of a body tuck within a run. A body tuck just at the wrong moment has the potential to ruin the entire event for the driver and team. The way the arm has been designed is to disperse the energy from the impact and not damage the shell. The parts weigh in at just 2.2g each and when designing the arm, RC Race Prep chose to use the production methods weakness to the designs advantage. The screw hole at the base of the flex arm can be fixed to the bodyshell to further support the rear of the shell. Upon impact, the layers around the hole will delaminate dispersing some of the energy from the impact. This means that on impact the contact patch on the wheel is effected as little as possible. This is a critical performance aid when running with a lightweight shell as the vertical load is applied down the arm to the fixed location point on the arm. The resistance given by the arm is also a key part of the design process. To change the flex characteristics, the designers produced a variety of arms with different arks and thicknesses. The result is an anti-tuck arm whose resistance is great enough to push the body back to its resting vacuum formed position, yet not so great to unload the wheel during impact causing the car to loose traction.
