Any Idea on Which Model KF??

[SDRiverRat]

I took my kids to the local Aerospace Museum and found this little gem inside!!! Almost walked right past it, but saw the folding wings!!!

Any ideas on which model and which Rotax?

Thanks,

Aaron

The engine is a Rotax 912 UL 80 HP, Not sure on the model of the airframe, but I think the airframe is a model 3 or a Model 4 1050 lb gross weight, judging by the airfoil shape.

The undercambered airfoil and the drooped wingtips make it no later than a model 3. All 4's, even the 1050, have no undercamber.

For what it’s worth, there is undercamber on the later wings... it’s just much less than the earlier ones.
