Woo Hooooooo - My RXs finally came back from Horizon on Friday, I finished the build on Saturday, and maidened on Sunday! What a great weekend!    
I have to say, and I say this with all sincerity - it was the best maiden flight ever! Period. She spun up smoothly, came up into a solid hover, and tracking was perfect. I had to dial in more gain on my new gyro, and then the tail was locked in solid. Sweeeeet!
I really like this head design. I think the Bell/Hiller mixing on the blade grips really helps to set up this thing on the bench so she's dialed in perfect. The only things I had to adjust for the second flight was the main needle on the engine, and the gain on the gyro. Everything was set up beautifully.
Since I wasn't breaking in a new engine I could start having fun with her right away. On the second flight I wanted to see just how much pop this bird has. I went idle up 2 on the deck, 2000 headspeed, and went full collective. This thing shot into the sky like a scalded cat on crack! I couldn't believe it! My Trex 600 Nitro has nothing like this Xtreme. She had so much pop I even went back to the bench to check my pitch. It was 13 degrees. I have 12.5 on the Trex, so I'm sure it wasn't just the pitch. Sweeeeeeet! This kind of climb rate puts a smile on anyone's face!
I got 3 fun fun flights on her on Sunday. The only issue I had was rolls. My first roll was not axial - more like a barrel roll. I went back and did many more rolls, focusing on my cyclic so I only put in aileron, and focusing on my collective, and I could not get a nice axial roll. So I thought about it a bit, and wanted to ask you guys - Do you think this is the phase ring off slightly, or something else???
I set up the phase ring like the manual says, but this is supposed to be just a good starting point. If you look at the link from the flybar cage to the mixing arms in the picture of the head, you'll notice that the link is not straight up and down. The guys at the local hobby shop noticed this when I was talking about the rolls, and they recommended turning the phase ring counterclockwise slightly and trying that.
Has anyone seen this issue with the rolls???
Multiple flips were cake with this heli/gyro combo. And one of my ugliest maneuvers on the Trex is rolling inverted, and pushing her into a big rainbow. She turns on me with the nose comming at me with the Trex, and it just looks ugly. On the Xtreme I nailed a perfect rainbow everytime. It was beautiful man!!!
