Maybe it could be the wax-like substance inside of its tail, coupled with the sheer force that he accumulates from the spin attack he does. Once he reaches terminal velocity, he slows his spin but the inertia of his spin is still prevalent. So when he veers his tail upward ever so slightly, the inertia then carries his whole body, launching him high into the air. Perhaps that wax-like substance is a great accumulator of force. Because even when he doesn't do the spin attack, he still has the ability to vault himself a great distance. For example, the one attack he does which is reminiscent of a Shot Put, where he steps to the side and thrusts his tail out, propelling him across a fair distance.
