Yes! Are you using front spool or one-way? Any car will have a chance to spin when braking. It's all depends on your car setting and the how is the grip will be when accelerating or decelerating. Shaft drive car will have a torque what cause the car to roll. The smoother the drive train it has, the less roll it will be. So shaft drive car will have higher chance to get uneven grip on left and right. In the case of using one-way, as there is only 2 wheel effective when braking, uneven grip will become significant and cause the car spin. BTW, we usually not using brake when run with one-way!
