Nope!, I wanted to, and had an engine and the proper motor mount, but the crank failed ASI, and the cam failed, so I gave up. The owner of the only legal 220 in a Cruisair (that I know of) told me that it took him several years and huge amounts of paperwork to get it approved, and the man worked for the FAA. I am not willing to spend huge amounts of time and money, to satisfy FAA people that probably have no clue of what is safe in any individual airplane. They pawn you off to engineers that will produce much paperwork, and charge large sums of money to make sure the FAA people dont have to make a decision based on their own knowledge. Sorry for the rant. ______Grant.
