Hi all, I'm building a Great Planes Extra 300s .60 size and am now contemplating powerplants. The choice has come down to either the OS 91 FX or the Super Tigre G90. On the up side I have never had any relaibility problems with OS engines but the down side is that here in Australia it is nearly $200 dollars dearer than the Super Tigre. $200 is a lot of money to me at the moment. I once owned a Super Tigre g51 once and power wise it impressed me. But getting the low speed needle settings correct was an all out BITCH!! I had numerous unannounced engine outs until I got it kinda sorted. Where are Super Tigres now made? Italy?? That would explain it... Kinda like a Ducati I once owned. Impressive as anything but really high maintenance.
I've spent a LOT of effort building this Extra and any input would be greatly appreciated.
Regards Shannon
