Fantastic, Bob!
Thanks.
Other commom modifications (besides VG kits) were the Robertson STOL kit, which replaced the split flaps with slotted fowler flaps.
Jack Riley also modified a couple in the US with counter rotating TIO-540 Lycomings (350 bhp and called the Turbostream), but don't think any made it out here. Burlair operates a beautiful turbo converted R model. Pretty sure he's spent over half a mil. Show quality.
