Sanwa’s new SDX-801 is so small (40.5×21x26.5mm) it can be placed in any R/C car chassis without any problems and at the same time lower the cars overall weight and center of gravity. Due to the small weight of only 50g the SDX-801 is also perfect for today’s touring cars where left/right chassis balance is a huge problem due to racing with LiPos or 5-cell NiMH batteries which creates overweight on the electrical side of the chassis. Expect it to take 0.08s to turn 60° @ 6.0V, while at the same voltage, able to achieve 6.4kg/cm.
