Classic IV with Rotax 912 iS Sport

[HighWing]

I made up my own "horse Collar" and after positioning the engine where I wanted it closed the gap with 4130. i made molds of Delrin and poured isolaters using a two part Urethane rubber. The oil tank is painted because I wanted to hide the hammered modification (near bottom) needed to give the quarter inch clearance I wanted between tank and cowl. Another thing that worked into the mount was the fittings that were used to mount the ignition modules.
