I have had one for several years. It started out with an OS 91 and now has a RAM 500. I find it harder to fly with the turbine, probably because it weighs more. It is quite fast with the turbine, not in Bandit territory, but fast enough. Philip is a good guy, responds quickly to e mail and requests for spare parts (dont ask).

Since it is a delta, it loses a LOT of speed in turns, so keep the power up. Landing is somewhat tricky also because if you bring it in nose high, you will be in a high drag regime, and must add power. One thing I dont like all that well is that it is very sensitive to aileron movement. You only need a tiny bit of throw to roll like crazy. So you need to make sure you are in trim before you take off. Bottom line, I like the plane quite well even if I have other planes that are more relaxing to fly.
