RE: Reaction 54 Jet Kit
Next step was glassing the balsa-tube to get a strong surface.
After some brain-washing we came to a method of mounting the tank to the wing that seems to be good enough.
We will glue a piece of gr10 with a key-hole in the middle of the tube and made a support for the front end. The mainplate is made of gr-10 and the former is 3mm lite-ply. That will be screwed to the wing with two nylon-bolts.
We use brass-inserts with M3-thread to hold the screws.
The tank-fitting is from Markus Richter in germany and perfect for pop-bottles. No drilling through the plastic, no leaking seals, no nothing. Machined alloy with a viton o-ring to seal the cap permanent. We will have fill-valve and vent inside the tank and a 4mm tubing that goes to a Festo-fitting on the bottom of the fuselage.
