How to Modify RC Planes for Greater Transmitter Power

When you radio-controlled aircraft is at high-altitudes, nothing spells disaster like a loss of radio connection between your transmitter and receiver. Interference can come in the form of other pilots, great distances, or obstructions that physically block a weak radio signal. Learning how to enhance the signal of your radio system can improve your vehicle's range, allowing you to fly around obstacles without losing control.

Things You'll Need

35 mHz receiver
Antennae
Scissors
1 10-microhenry RF choke
0.02-inch diameter piano wire
5mm diameter heat-shrink wrap
10 mm diameter heat-shrink wrap
Pliers

Instructions

- 1
  Shorten your antenna leaving only 4 inches of the original antennae wire connected to the receiver.
- 2
  Strip the end of the receiver's antennae. Dab a small amount of solder onto the heated tip of the solder-iron, then apply it to connect the 10 microhenry RF choke to the receiver.
- 3
  Sever a section of piano wire measuring 7 inches in length. Touch a small piece of solder to the heated solder-iron, then apply it to connect the end of the piano wire to the available connection on the RF choke. The RF choke should be positioned between the piano wire and the shortened section of the receiver's antennae.
- 4
  Slide a 2-inch section of 5mm heat-shrink tubing over the soldered connections. Apply heat with the hairdryer to shrink it snuggly around the connection. Position a 1-inch section of 10mm heat-shrink tube over the RF choke. Apply heat with the hairdryer to encapsulate the RF choke.
- 5
  Squeeze the terminal point of the piano wire, bending it into a loop shape to prevent it from damaging anything.
