With smooth inputs this is a stable, nice flying canard aircraft. However, it is still slightly unstable. At speeds below 400 mph or so, she can be pulled into high alpha type maneuvers. That's where the RCN thrusters come in. They allow the pilot to then get it flying forward again. I've been able to do Cobrahead type maneuvers, tumbles, wicked flat spins, and even flat decents with no forward airspeed. Now add to that REVERSE Thrust, and s**t gets real crazy. The thrust nozzles start in neutral and you can select forward or backward. I like to come over the top of a loop, then when it is headed straight down, throw it into reverse, and if the timing is right, it stops just before hitting the ground and then starts going back up. It will not fly this way very long, so when it starts to turn around, throw it back into forward and RCN it into controllable flight again. What a blast!
