ASK-13 Refresh
Posted: 01 Nov 2021, 03:58
Hello All,
For what it's worth (minimal ) I thought i'd share some photos of my ASK-13 tidy-up. This is 1/5 scale, glass fuselage built-up wing which I got 2nd, 3rd, or 4th hand and in hindsight (its a wonderful thing) paid too many pesos for - note to self don't buy model over the interweb!).
Upon delivery (did I mention I mention it was located 2500km away) it was evident that the model had less than an easy life, once I got it on the bench.
The nose had been repaired, repainted (didn't quite match, and very thing glass with lots of putty, wing covering was not great and in film. It also had an electrical whirly thing, which wasn't scale and had to go.
After my last outing and a hard arrival (which i admit was on me - partly because I hadn't set up my new TX correctly) which resulted in a damaged wing, I decided to embark on this project. At one point in the model's life, it had worn the markings of the Southern Cross Gliding Club and as it was still in those colours elected to go with them again. BTW - when I contacted the gliding club for help with reference photos the Secretary could not have been more helpful, which is what I've used as a reference for the marking stencils and decals. Upon removing the covering (which hid lots!) I was amazed at the questionable selection of balsa used for various applications. The wing sheeting was less than 1mm in thickness and was basically crumpled at the root rib, the shear webs are at least 5mm thick. Also that both wings had been broken previously which explained the kink in one leading edge... So i did my best to repair and straighten them, prior to covering them with Bem silk. [attachment=0]
I reinforced the root rib sheeting with .6mm ply glued to the underside of the sheeting, there was little i could do with the LE sheeting unless i replaced the lot! I elected to see (hope) that the bem silk would offer greater rigidity - which it has.
More to follow - my aim is to get this ready for the Bordertown aerotow on November 20th!
Cheers
Stephen
