Howzit guys

Can anybody tell me if there is anybody in gauteng flying a cheetah with a 2200 jab motor on it?? Any pro's con's to this configuration??? i Have been flying the jabi sp and ul120 with this motor and as far as i can tell its not performing bad at all.

Too cut a long story short would this configuration be powerfull enough to get 2 average okes a full tank(s) of feul and maybe an "underpant" in the baggage compartment off the ground at 5000 Ft :?: :?:

waiting in anticipation for your answers
thanx :? :? :?

yes had a look at it, there is a bit of interest hence the question on performance.

I have flown one form springs 2 up. It's no rocket ship compared to the 912S powered cheetah but it flies just fine. The main difference is length or runway used. Becuase the jabbie engine swings a small prop the acceleration is not as brisk as the big propped reduction drive engines. So acceleration wise it feels 'pap' but once you get the airpseed up it flies at pretty much the same 85-90 mph as the 80 hp Rotax. SO unless you have a need for real short field ops it should be no problem.
