RE: Do you remember when....
I started with an electric glider with an on/off switch for motor control and two buttons on a box that "pulsed" the rudder.
First glow plane was a Cox EZ Bee II with a two channel "real" radio.
Finally in the early 90's I bought a four channel radio and a real live O.S. engine.
I still use only 4 channel radios and two strokes (mostly, I have one FS and a few electrics).
I prefer silkspan and non-CA glues, a step backwards in many minds, I'm sure.
