box and install (4) “AA” included batteries into the batter y
holder. Follow the configuration molded into the battery
holder. Re-install the receiver battery holder back into the
radio box.Plug the connector on the receiver battery into the
socket on the receiver switch wire. The receiver battery
connector can only be plugged in one way. Tuck the wires
into the the groove in the radio box so that they do not get

hole in top of the radio box. Place a 1/8" long piece of fuel
tubing over the antenna tube and wire to secure in place.Tip:

Run the antenna through your fingers to straighten out
kinks before running through the antenna tube. Also,
applying a small amount of soapy water to the antenna
wire will allow the wire to slide through the tube easier.

Filter Oil (DTXC2465) is available from your local hobby
dealer.Attach the adapter tube to the air filter base with one
