    Thanks for the replies
    I assume hysol (1994 kit) ,chopping the Spars individually and replacing one at a time may be an option. I will get 2 spars and inserts from kitfox.
    My rear spar maybe OK we wont know untill the bent front spar is removed or temporarily straightened.

    Any specialist aluminum has to come from overseas and I am happy to support kitfox.
    My aileron doesn't look right so will be replaced and the Spars can be boxed together.

    The wreck has just been released by my insurance so I am still assesing.
    I will get a price for ribs etc if cutting doesn't look feasable

    Any ideas on using the later style ailerons?

    My Series 5 dates from April 1995 and used Scotch-Weld, so the change to Hysol was definitely after my kit was produced.

    Strongly recommend you buy the spars from Kitfox. Aluminium suppliers here in Australia only supply in 12 ft lengths and if your KF5 has the same wing as the KF7 then suppliers other than Kitfox won't get you the length you need. I know this because I had an "incident" on my KF7 wing build and ordered locally - Kaiser manufactured in the USA. I had to design an extension to the outer section for an extra 18". Also, as already suggested by Jim Chuk, a heat gun will soften Hysol if that's what was used. Any other adhesive used in the original build - don't know.
