Here's one for you, makes you look like you know what your doing..........or not..........
With the CG set rearward, gain altitude and with the nose pointed up, hit full down and full left rudder. As soon as it flips inverted into a nice FLAT spin, drop the throttle back and let off on the rudder. Just hold in the elevons and it will now spin down fairly slow.
If you want to go back up, just feed in full rudder again. If you want to go back down, let off on the rudder. Up n' down like an elevator with complete control using just the rudder. Let it come down a low as you dare, the reaction to the change in direction is instant.
lookin', you too
