All is going well with the build, nice and slowly.
Thought I'd touch base with forums over progress. Pretty happy and confident with it all, but always nice to get some feedback.
POSITION OF MOTOR MOUNT
I'm getting closer to the step of gluing the Motor mount into the Main Airframe.
I've chosen an Aeropack Tailcone and so I've been working on the positioning of the Motor mount in respect to the Airframe - protruding by 1.06" (very close to 27mm).
It all looks fine, I can see that with the spacer installed (for use with Cesaroni motors), we have about 13 to 14mm of space left for the AFT closure (what is screwed into the rear of the motor casing) to butt up against the spacer/motor mount. What I'm trying to do here is double check my work by reconciling the gaps .... double checking everything is okay by confirming that a motor would fit fine. Can anyone vouch for that?

AFT Centering Ring
I decided to use thin nichrome wire instead of paper. I found the paper could easily rip. Not sure what other people use, but it seems like a more reliable way to remove the rear CR during construction.
Just thought I'd share that

GLUING FORWARD CR to AIRFRAME
I've decided to use 24 araldite for several reasons:-
1. It has a strong final bond
2. It is not too runny, so easier to smear up near where the FORE CR needs to be....not so many drips.
I was thinking of sanding the area internally where it would be glued with Grit 80 Sandpaper, then smearing Aradite over a distance of about 2cm, probably about 1/2 cm below where the CR needs to be. Then as I push the Motor mount in, it would help to smear the glue where it needs to be...then I'll rest it vertically overnight.
I'm sure there are a million and one ideas and methods. What do other people reckon?
Cheers!!
