OFf Road Aerodynamics

​One of the interests I have with RC is experimenting with new concepts. Granted, this is something I picked up a number of years ago from a sponsored Trinity / Losi driver, but I have expanded on it, perhaps too far. You can shrink a RC to 1:10 scale, but you cannot shrink the atmosphere, or the forces acting on it. As such, the only way to compensate is to increase the size of wings in use. In general, the only times that aerodynamic forces come into play off-road is when the vehicle is airborne and on the straights. These tips will not change slow speed driving as there is little airflow during these times. An increased side damn (vertical) will help with tracking down the straightway, and both the angle of attack (angle of wing compared to the ground) and the size of the airfoil (horizontal) will result in changes during jumps and down force traction on the straights. I have found improved lap times with the simple enlargement of the rear wing, especially on slick tracks. You can either simply increase the stock cut out from the manufacturer, (I know going outside the cut lines seems odd) or add additional sections as needed. As with tires, I have been playing with a selection of wings as an additional tuning tool, albeit one a hell of a lot less expensive than the cost of rubber.
