Mustang II Tailwheel to Tricycle Gear Conversion


A few tri-gear Mustang IIs


On June 28, 2017 after 19 years and over 1,000 hours of flying my Mustang II I decided to go ahead with the plan to convert mine from a tailwheel to tricycle gear configuration.
The most common question is: "Why?"

My answer is that I wish to have my sons and eventually my grandchildren fly the plane and we determined that for them to easily, comfortably and safely fly the Mustang II a tri-gear would be better for them.
(There have been numerous discussions about tailwheel vs. tricycle gear, but I don't wish to go into that here.)


Major Tasks
  • Determine if an alternate engine oil sump is available that could accept a fuel injector from the front.
    (My IO-320-B1A engine has a rear-mounted fuel injector which would interfere with a nose gear assembly.) - Complete
