Here is build of Hammer F3F from Blejzyk.
Just to cover the basics as build is easy and straight forward.
The most tricky part is to glue the wing joiner in one wing and the "drawer" in the second one.
How to do it ?
You need Epoxy 5 and 60 min .
first we need to align the wing joiner and "drawer" in the wing, and glue it with the 5 min epoxy (small amount) keeping the position of the wing and the dihedral as required.
After it dries just fill the gaps around with 60 min epoxy - can be done with 30 min as well - but with 60 we can be sure that glue nicely filled in all the gaps - so good idea is to check every few minutes if we don't need to add some glue
Producer suggest the dihedral of 60mm (30mm on each end tip.) but can be less for sloping and more flat field flying - up to us - so I went for 60mm
TIP. good idea is to push some bit of foam into the channel where the wing joiner is - as deep as the drawer and wing joiner goes - or you may need a lot of glue
Next we need to cut slots for the supplied wood blocks - then epoxy them in.
