===== Finding the right glue =====

I tried 3 different glues. The model we use (mini talon) is made with "EPO" expandend [[https://en.wikipedia.org/wiki/Polyurethane|PU]].

There is a good overview of all normally used materials on this [[http://wiki.rc-network.de/index.php/Hartschaum|page]] - also to available [[http://wiki.rc-network.de/index.php/Klebstoff|glues]].

I tried:

* UHU POR - special glue for Styropor and similar foams. * UHU Plus - 5 min two component epoxy * Hot Glue (Patex)

The results:

====== UHU Plus ======


====== UHU Por ======

works well. good fixture and waterproof:

But - the glue has to be applied in the right way! It has to be thin and completely dry before putting the parts together:

Bust is to spread it equally with a (gloved) finger:

====== Hot Glue ======

Hot glue also showed very good results, both for fixure and for waterproofing.
