Hi DiscoWings,

>>is the prosport a lot better then the IFS version? Or marginally better?

There are significant differences. A lot more than the price difference suggests, but the differences won't matter to everyone. The ProSport was intended for contest pilots that fly hours a day practicing. They do have a bit more power(.2HP I think I remember), and heavier duty components, such as bearings, crank, rod, and prop shaft if my memory serves me. I have a list somewhere. If I can find it I'll edit this post and put it here.

I found the list. Here it is:

- Titanium prop shaft
- Better bearings
- Better conrod construction
- Different big end on rod
- Different porting
- Different crankshaft
- Carb diffusor

>>The engines sold by MVVS Canda, they are IFS or prosports?

He sells both.

>>man who would have though its cheaper to import stuff from abroad then to get locally...


A couple of years ago it was a lot cheaper than it is now when the the dollar was actually worth more than the Euro by quite a bit.
