The Astron Cobra
My Astron Cobra is a complete reproduction of the kit version of the
Cobra from the early 1970s. It uses a balsa transition and nose cone
that I found in a local hobby shop's loose parts bin, though I did install
a motor retention device between the motor mount tubes (a length of nylon
screw, with a nylon acorn nut threaded on to retain the motors) and use
a centering ring forward of the motor mounts to avoid the very annoying
technique of puttying in the gaps around the mount tubes with tissue soaked
in glue. Several coats of primer and gloss black, and a judicious
assortment of decals from Estes assortment sheets, and it was ready to
fly -- and fly it does. One of the first comments I generally get
with it is how light it is; it flies well even on 1/2A6-2 motors, though
that delay is a little short. I need to make up some more 13 mm adapters
and try flying it on 1/2A3-4T and A3-4T motors, as well as trying Quest
A6-4 motors, since I can't get 1/2A6-2 or A8-5 any more.
