![]() The reduced corner friction doesn't necessarily increase the speed at which the car can corner, but it gives greater control to the driver: with steering, the car is influenced by the amount of power or braking the driver applies and a little bit of tyre friction, rather than engine power or braking plus the greater tyre friction that un-steered front wheels cause. They're manufactured sufficiently well that there's negligible toe in a straight line and, due to the steering action and independent front wheels, much reduced friction in the corners too. If the solid axle has caused any increase in friction in the corners, its effect in my experiments has been outweighed by the gains made on the straights.įar better than toe or even a solid front axle is working steering, Ninco F1s being the best of the main RTR brands in this regard. With a solid front axle the wheels are aligned with the direction of travel on the straights, with loose stub axles they're not and so friction is greater. If my experience is anything to go by (and I've done this mod to dozens of cars, always with the same result) you'll see a slight increase in straightline speed and reduction in lap time. Without altering or modifying anything else, fit a solid front axle in place of the two stub axles and then drive the car over the same circuit. ![]() On track they will always toe out as a result of the friction from the track trying to push them backwards. In both cases the tolerances as manufactured allow the wheels to flop about, I.e., toe in or out. It's pretty easy to experiment with if you have any Fly or Carrera cars that have front stub axles. Succinctly, my findings were that toe in or out made performance worse the cars were slower on the straights and not noticeably different in the corners. QUOTE (Kevan, 17:27) Toe on the other hand should help, I have plans to make a chassis with slight toe in, my thinking being 2° should help reduce front end deslots.Īlthough I've never experimented with camber, I have with toe in a roundabout way by removing it from cars that had it as a result of being fitted with wobbly front stub axles. QUOTE (dvd3500, 16:40) We all know the front wheels more or less are along for the ride so I thinking getting them to toe in and ride on the edge might actually help. I've not got one to hand to look at, but from memory I'd guess that you could probably add as much as 5 degrees, positive or negative, if you wanted to. They have independent front wheels with long stub axles retained by three grub screws, which allows you to set up camber if you wish. ![]() I've not experimented with camber, but have a look at some of Avant Slot's cars.
