My ekomS ekiN (Nike Smoke in reverse colors). Sorta flyin' on a CTI K740 C-star. Begad! About 300 feet up t' thrust rin' on our adapter gave up, and t' motor slid about a foot up into t' airframe, wreckin' t' lower centerin' rin' and burnin' up about half me motor tube. Ahoy! Should be a fairly simple fix! T' altimeters fired as they should, so everythin' else be recovered safely.
