Radio Control Equipment
(Updated on March 2, 2022)
 

When a young boy, I was first attracted by Radio Controlled model boats. Later, in the sixties I built my first radio-controlled model aircraft and homemade radio. At the beginning of the 1980s, I made a comeback still with an all home-made equipment (aircraft and radio) and learned how to properly pilot with the help of a skilled instructor (thank you very much André) . I still enjoy flying some models in the summertime.

My first radio control receiver.
  I built this 2 tubes regenerative receiver around 1958 and tested it in a model boat. I recently repaired it, using as many original components as possible. It is now in full working order. Click for schematic diagram.
 
 


 

The TF7S Transmitter.
  This is one of the RC transmitters Lionel and I have built : it was designed by F. Thobois
 
 
 



  LM1872 Receiver.
  I have built many receivers of this type using the National Semiconductor LM1872 integrated circuit : they were simple but efficient
 
 
  



 

ATV Transmitter.
  This is the home built 1255 MHz FM ATV transmitter used with an onboard color camera carried by a model aircraft. Its 10 mW output allows reception of good pictures inside a 300-meter range, the receiving antenna being a small home built 8 elements Yagi. It measures 8x5 cm and weighs less than 40 grams.
First flights took place in 1994 at the airfield of the local model club. You can  now buy a 2.4GHz video link off the shelf, but at that time it was a kind of achievement and a lot of fun !
 
  


 

  1255 MHz GP Antenna.
  The above transmitter is connected to this small Ground Plane antenna  mounted above the aircraft wing. The integrated circuit under the front left radial is for scale.
