07/31/2009. Remarks by Walter van Tilborg: "After the ambitious Bede BD-5 Micro project had stranded, many builders were left with uncompleted airframes. Rod McKenzie was one of at least two designers (Harvey Mace with his M-102 Scorchy being the other) trying to help.
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 undercarriage, 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."
