That is a great story 049 flyer
I was a middle teen in the mid 70's and had several mentors...they had a lot of influence in my life...
One of them was a Naval Aviator during WWII, and had his early experiences in R/C with Bramco and Citizenship...he also had a Quadraplex 4 channel...a Schmitt reed set-up...(which I still have)
Anyway...he was building a Litco flight pack, and I thought I'd give it a try...
I remember that the servo (mechanics) kits that I had were similar to some of the Ace servos...the cases were in 2 pieces, split down the middle vertically...(were those Deans mechanics??? I don't remember exactly, but they were white plastic with a black insert on the top, over the gears)
