I have the Helios 63e, and Ive flown (attempted) P07 with it. The plane is capable..Im not.
Ive reviewed the P09 schedule, and I dont see anything in it that the Helios couldnt fly.
You'd have to watch that triangle loop though. I found that pulling REALLY hard sharp corners on the downlines of a triangle maneuver, it will get loose on you. However, with practice you should be able to cut a nice clean corner without overdoing it. Its possible too that Im just coming down at too shallow an angle, and Im pulling late. Its one of the things I gotta work on.

Looking at the P09, I can see areas where the Helios would excel in certain maneuvers. The helios is very locked in on rolling maneuvers at any attitude. This is one of my favorite things about the plane, no track deviations during rolls. Any of the rolling vertical upline sections would be really nice. Spins with the Helios are absolutly georgeous, very smooth, not too fast, exits by just neutralizing the sticks. It will drop nose, and then enter the spin, with no wing wobble or anything.
