I have turned my 750 STOL in to sort of a hybrid.  I removed the LE slats some time ago in order to see a bigger number on the A/S indicator and at my age I'm not landing on 400 ft. gravel bars - might have 50 years ago!  I inquired of Roger a while back if the 'Speed Fairings' for the Cruzer would be available for the 750 and he replied they're working on it.

In the meantime, I decided to fabricate strut fairings for the rear upper strut attach area which I consider the 2nd worst aerodynamic juncture point.  I made a template out of thick paper and transferred that to .016 aluminum.  Took a bit of trimming and fitting but looks better than the previous.  Probably won't see any increase in A/S but looks better cosmetically.
