Hi All:



"My Kitfox" new owner is currently performing a

complete restoration.  He already applied sand

blasting to the fuselage, and the applied an epoxy

primer and a polyurethane coat.  It is in good shape. 

The wing lift struts however are a different story. 

When he attempted to remove the bracket that attachs

the jury strut to the wing lift strut, he found that

the strut was heavily corroded.  He said I'm lucky to

be alive.  I flew this plane for the last time on

December 2004, and then it was for one and a half year

on my backyard, exposed.  This rust may have developed

during that time frame.  I will never know.



What really matters is that now I need a pair of Wing

Lift Struts and Jury struts for a Kitfox II.  I have

some questions regarding my alternatives:

- Could I adapt Model IV wing lift struts to a model

II?

- Could I get a pair of Model II wing lift struts and

jury struts from John McBean/Kitfox LLC?

- Do any of you have a pair of Model II wing lift

struts in good shape for sale?  Please not rust!!!



Thanks for your support!!!



José Toro

I took my Model IV to a weld shop and had them copied in the larger size.  I

may have the lighter mod IV struts available but don't know if they fit and

I suppose shipping would be terribly high.  Bob u.

Bob:



By lighter and larger, do you mean different diameter?

I've been told that the wing lift struts are different

in model II and IV.  However, if the Model IV struts

can be adapted to the Model II, I'm willing to buy a

new pair.  



I probably won't be able to copy my actual struts to

build new ones since one is longer than the other, and

I know for sure that both were incorrectly installed,

which means that probably both were wrong in terms of

length and angle.  You won't believe how beautiful

this Kitfox used to fly with incorrectly installed

wing lift struts.  Our goal now is to do it right as

part of the restoration.



regards!

The old ones I think, if my memory serves me right were 7/8" dia but were

smaller than the new ones for sure.  Have NO idea if Mod IV struts fits the

MOD II.  You would have to go to Kitfox for that.  Bob U>

The model IV struts are longer than the model II since the bracket 

location is further out on the spar.. I could get you dimensions if you 

need them.

José Toro,

If you change the length of the wing struts, you will affect the angle of

the bolt holes that were drilled in the spars at the airframe mounting. Even

a little length will render the current spars unusable or worse if you bow

them to fit, the spars may fail in flight. Also you can not move the spar

connection for the lift struts with out weakening the spars. Please consider

this .....



Thanks, John Oakley
