Does a Kitfox wing fit on an Avid mk4 ???

Hello,

the idea is a possible weight increase of the weight with proven wings.

The newer Kitfox have in germany 472,5kg MTOW the avid mk4 only 450kg MTOW.

Has anyone ever tried something like this?

Kitfoxes use a .065" wall thickness on their spars.  Avid Heavy Hauler used an .083" wall thickness.  Of course  the spar stiffeners used help to give the wing strength as well.  I would wonder if the extra gross weight for the Kitfox is due to differences in the fuselages.  Jim Chuk

Hi Martin,

 

I am in the process of making changes to my MK IV to accept KF4 wings. From the information I have found, the wings are different as Jim mentioned, and the fuselage is also different. The spar carry throughs are 1" x .035" wall (larger on KF5/6). I don't remember the increase the strut carry through, but I could look that up.

 

Struts are also different, and attached at a different point.
