Very cool Ed!

Those do look like some vintage servos! There's something nostalgic about building a 30-40 year old design with radio gear that is of a similar period. Unfortunately I parted with most of my vintage radio gear while still a kid. Back then, it was of course not vintage gear. I was particularly fond of some little Futaba S20 servos that I had - miniature and expensive by the standards backs then. I build many a small model with those servos.

Replied to your PM.

Ian, by the way, Ed's 50 oz SP sounds like a very respectable AUW for a stock glow version. I'm actually wondering if my 40 oz version will fly more like a glider than a little pattern plane!
