I got a couple test flights in yesterday. It was a little windy but it flew fine. The PBXL is very good in harrier, spins upright and inverted very good, tight and held altitude, landings are slow and I can taxi it. I did let it get some speed and it did fine, no flutter but watch the sudden dives, knife edge forget that it will not. Overall a good easy fun project and for the money ($32 for a laser cut kit) I give it "a should buy". If any of you have questions email me at [email protected] Thanks, Jeff Williams
