Hi Scotty,

Yes that thing flew away probably 2 years ago.

That wing failure thing was not as easily explained. I was not flying very fast, maybe 175 and pulled up hard at the center and it popped the seam down the leading edge of the wing and peeled off a big section of the top of the wing.

On the next one I glassed the entire leading edge of the wing from the inside and never had a problem (of course until it flew in the LA river at about warp factor 5)

Ouch [:'(][] that sucks ... I find this to be a weak point of ANY composite wing. Even on JMP firebirds these leading edge joints are weak, and pop with a squeeze from the outside ... On my Comp Bobcats i always used to just pour some gorilla glue down the LE .. I failed my wing once by pulling what was probably well over 40 Gs + , but the edge never split, only one of the formers gave allowing the wing tube to bend 15-20 deg .. i still landed ... After that I laminated all inner and accessible areas of the wing with heavy carbon. It never failed from there on out


Pete, Bobcat looks nice I might have to go for #5 on a composite one some time myself ... but lately the UltraFlash has been my go-to beat-it-up sport jet
