– Welcome to the forum.
Apologies if you’ve seen these already, but there is a basic MX250 build manual here:
You will also find links to various MX250 builds in this thread (keep paging down).
Note: Unfortunately, there have been technical problems with some photo links on old threads.
Contact Tribute directly to confirm they will ship to Luxembourg.
( The kit is packed on a pallet for delivery. )
This is the two-part bonding paste I used to join fibreglass panels to metal on my (non-Tribute) build.
( Where you add a separate catalyst to activate it. )
This was a rough test piece I made to see how it worked and check the strength of the join.
By chance, I found this piece recently and the join is still rock solid some 3.5 years later.
Good luck, Paul.
