Ballast tube mounting

The ballast tube was glued in today with RG moulding epoxy mixed with 0,2mm
glassfiber cut to achieve maximum strength.

First the ballast tube was used as a foundation sanding the bottom of the fuselage. To pce. of 80 grit paper was taped around the middle of the tube and in the end towards the tail. Rubbing some in the bottom of the fuse to make sure the epoxy have as good binding in the glue joint as possible.

Then after the bottom of the ballast tube was sanded with the same paper.
Epoxy was applied to the bottom of the ballast tube. Doing it this way, a tip is
to recon were the glue hits the canopy opening when putting ballast tube inside.

Leave 4-5cm of that area without glue, and slip the ballast tube inside, and apply glue on the missing spot thereafter.

A long piece of tape were applied around the slug opening, allowing to "fish up" the upside down ballast tube, to put it in it's place, turn it around, and press down to the fuselage at the correct choosen spot.

The spot which I choose were at a CG a tad in front of 112mm.

Then 7 slugs of ballast were put inside the tube, to make sure it is pressed down to the fuselage while the epoxy dry and harden. Next step in the evening, may be to install the servo tray and fuselage wiring...........
