Same with this one as with the others changed out the 72mhz rx, new batt and kept the servos.
All three were made with aliphatic glues and Ambroid. I never really thought of glue joint degradation and the monokote getting brittle, something to watch out for.
Good luck
I forgot that I also still have a Great Planes Spectra electric powered sailplane from the early 90's. It was my first electric and had a can motor and used 6 cell nicads as well. I had thought about upgrading it but have too many other builds in the queue. I used to be able to speck out the 2m Spectra even with the heavy battery pack. Now that my eyes are 20 years older I could probably speck it out at half the altitude.
