No picture check your albums. Please do an internet search maybe you'll come up with one I couldn't find, I need all the help I can get.

Surprisingly no pictures. Maybe Larry Teufel has one or two?

Is this a Wren behind the 700?  I think they were also used by Air America.  Anyway, another STOL for sure.  An interesting one relying on something else than high angle of attack to obtain Stol characteristic.

These are really interesting pictures.  It just looks like a hybrid, which it is, with H295 wingtips and gear, H700 motor.  Gives a interesting look into what the 700/800 series would have looked like if the effort had been made to find a new supplier for oleos and gear legs. 

I also do wonder what the performance was like in this configuration...better off the runway than a normal 700 by being lighter.  Better than a 250 or a 391?  It had the lighter weight 295 cage with no gear boxes for a tricycle gear, light weight wing tips, and lots of power......  Probably fast at altitude as well!

C/n 1474 originally a 1400 series H-295 was modified by Tom Teufel to be the prototype for the H-700s later it was converted back to a H-295, which seems to indicate to me the that the GO-480 was a better configuration for STOL characteristics. I wonder if this cowling had better cooling properties than the H-700 series. interesting placement for landing lts.

Rodney Thanks for posting the picture it even shows as a prototype what would become the H-7/800 paint scheme.
