Who Am I?
I am a mechanical designer. I have a three-year diploma in Mechanical Engineering Technology, and I am a Certified Engineering Technologist (C.E.T.) member of OACETT (http://oacett.org). I am also a very serious aircraft and history buff.

Miles M.20 Proposed Mods 2021/03/13
Test pilot Eric Brown flew this aircraft in January 1942. He reported that "although surprisingly nippy in performance, could not match the Martlet, Hurricane, or Spitfire in manoeuvrability". It lacked also the excellent deck landing characteristics of the Martlet.

Accounts compare the M.20's performance with that of Battle of Britain aircraft. The M.20 (345mph at 20,400ft) was powered by a Rolls-Royce Merlin XX with a two&#8209;speed supercharger. A Hurricane IIB with the same engine did 342mph at 22,000ft. A Spitfire VC, powered by a similar Merlin 45 did 374mph at 13,000ft. The Spitfire was armed with two 20mm cannons and four .303 machine guns. The other two aircraft were armed with eight .303 machine guns. All these figures are from the same reference.
