Model III and IV Differences

Gents, as you probably know by now, I've got a model III which sustained heavy damage during a tow accident. Type IV parts are availbe from Kit Fox, but I think type III are limited, therefore could someone please list the items that are compatible between the two. It'd sure help me move this thing along.

Thanks,

Dave, Thanks for your reply. What about fuselage measurements, i. e., width, wing attach incident angle, the structure in the cabin top.

Chuck,
I have always hesitated commenting on things that I have no real life experience with, but I know of several IIIs with IV wings. I also know that the landing gear we make will fit a I through IV with just a little tweaking width wise on the cabane. Then the cowl is different as the windshield angle is different. Vertical tail is also taller on the IV.

The model 3 underchambered wing versus the 4 ,..if you can, take a ride in a 4, its faster, landing speed is higher, the 4 will sink faster then the 3 wing, there are other subtle differences, you flew your 3 how many hours before the incident? If you liked its characteristics try to find replacement model 3 wings, if you would like more speed get some 4 wings, but id try to fly in a 4 first so you can compare

Thanks for the replies, as time goes on, I'm learning more and more about this critter.
