Hi,

Is there anyone here on this forum that has actually flown the old blip-blip radios? How difficult was it? I would for sure want to try if I had a chance. But I guess to use such radio today would be a hazard with great risk to get radio failure (frequency disturbance etc). I have an old Grapner Variophon blip-blip (might try to get it in working condition).

Bo,

I did fly with my scratch build blib-blib (tip-tip , Dutch) radio. No reeds but electronic (Schumacher) tone filters and Metz (German) servos (no escapements) for rudder and throttle.
3 channel, two for rudder, one for 2 position throttle.
I think these tone filters are also used in the Graupner Varioton.
First picture was with two channels and Webra Diesel, second picture is my "new" four channel simultan transmitter I did use with a Webra Glow star.
The battery indicator I later use in one of my digital proportional transmitters, picture 3. (A copy of the circuit of a Simprop transmitter)
Nice period, I did learn flying myself.
I did use auto stabil own design models, so less to control. See picture one, dihedral!
The (Glow Star) engine did have two position throttle, full power and idle, possible with one channel. For rudder I did use two channels, one left, one right direction.
