McKenzie MRO – Micro Recovery One

McKenzie launched his M.R.O. (Micro Recovery One) in 1980 (first flight June 18, 1980) and although the BD-5 was transformed into a tractor type aircraft with a fixed tail wheel type landing gear, the M.R.O. left the basic BD-5 structure (including the tail features) intact.

McKenzie installed a 72 hp McCullogh 4318A two-stroke engine in the M.R.O. and plans at the time called for the marketing of conversion kits by Macair Associates USA, but no further aircraft were completed.
