RE: Extreme composite Pro-Line
Actually I flew through the P-07 sequence with it and it had plently of fuel. I was on the throttle a little more and flying further out and larger. I decided to land when I got a reminder from Tim that it was time start thinking about landing, so I didn't get throught the six sided loop with 2/4 on top. The motor quit when I was on final, but I'm pretty sure that it was because I pulled the trim all the way down.
The biggest thing I noticed with the airplane was its tendency to pitch down with the application of rudder during a radius. Tim already told me that the CG is not where Akiba specified, so if he trimmed the airplane with the CG in that location, it was likely the culprit. The airplane felt very comfortable during the entire flight, and the only thing I didn't get a good handle on was the snap. I didn't switch to snap rates, so I can't comment on that. The airplane spins fine, I think Tim said that it flew out on him using only rudder and elevator. I used only rudder and elevator for the 2 1/2 turn inverted spin and it held just fine. I can't comment on the upright spin characteristics as I didn't do any, and Tim's spin is upright, so that may be a possibility. Also the CG not being in the same place may have something to do with it as well.
I was pleased with the way the airplane flew. My first flight on it was at the Lake City, SC contest three weeks ago and I had just gotten out of the car after a 3.5 hour ride down. The wind was howling, I would say close to 25 mph and I had a transmitter put in my face and an offer to fly a new airplane; I couldn't refuse. It surprised me how well it locked onto lines in that wind and felt locked in throughout the entire flight. For those that haven't seen a ProLine in person, it's gigantic, with a generous side area on the fuse, so that struck me as odd that it locked in so well. Not complaining by any streach of the imagination, just cool. That first flight, Tim did have me to some vertical uplines with a roll to the left to see if I could tell that aformentioned displacement was prevalent, which it was. I didn't notice it on the last flight through the P sequence as much, not that I was trying to avoid it, it just didn't stand out that bad to me.
All in all, it's a great airplane. I think Tim hit everything that could be mentioned about it. I certainly have noticed an improvement in his flying after having switched to this airplane. I would say it's a keeper.
