Thanks for the info Jack. You echoed exactly my concerns about the EZ Air, so I'll abandon that idea. Can you give me the make/model of your gyro? I agree about the takeoff roll being a high-risk phase. If a gyro will help keep it tracking straigt, then I'm all for it. Any pics of your wheel wells showing the routing of air lines and servo wires will be most appreciated!

There's definitely light at the end of the tunnel now on my build. Initially I'd built it exactly per the BVM Supplemental Instructions, and it was incredibly tail heavy. BVM has the ECU, air multivalve, fuel pump, filter, UAT, etc all in the engine bay. Man, that was a lot of weight aft. I got demotivated knowing I was going to have to basically start over and move everything except for the turbine up front under the canopy and windshield. Then, it seemed like it was one step forward, two steps back. I got demotivated. But, I got back into it a few weeks ago and now I'm close to the finish line...got my "building momentum" back!
