I always thought the Centuri Skylab was neat but never had one. Being left alone for the weekend my mindsim got the better of me and decided to do an RC rocket glider themed version.
I sat down and did some mass balancing Sims to convince myself weight and dimensions would work and the location if the wing and lateral stability, then looked in my parts drawer. I had some 2" tubing and 2.6". I picked up a bt20 nose cone pack and two white motor tubes for the tail thruster.
I thought styrofam coffee cups might work for the transition and nose and lo and behold the base of the cups were 2".
I also found some small paper cups and they nested in the base of the foam cups to extend the nose. I doubled the foam cups for support and used a Depron disk in between them for stiffness and glued a coupler through the base for a shoulder.
I used a doubled cup for the transition.
I'm using an 11" chord 27" span Depron wing with two carbon spars.
Glide tests are done and it is looking good. I picked up some gold monokote trim for the wing/solar panels because I think it will look better than silver.
It's 43" long and 27" span and 7.25 oz dry, rtf should be right around 11 oz which is my sweet spot, looks like CG will not require nose weight.
I'll cover the foam nose with white vinyl to protect it. I picked up some aluminum tube for rail button standoffs because the nose diameter is larger than the rear by 1/2".
