Actually, I'm at the IMAC NATS at this moment and there are two Aeroworks Ultimates flying and doing very well. One has a DA200 in it flying Unlimited and the other is a DA170 on pipes flying Intermediate and goes like a bat out of he!! in the vertical. I witnessed (actually judged) both planes/pilots doing vertical snaps and the plane actually stopping from losing all the energy and just powering right out

I actually had the H9 version using a DA150 on Greives pipes using 9 3/4 inch headers and a 32x10 Mezjlik and go up hill like gravity was a passing fancy
