4.2 If using a Spektrum AR6000 receiver, route the antennas down the inside of each rear landing
gear strut and secure them in place with clear tape. If using a 72MHz receiver, route the antenna
out the side of the model, then into and out of the antenna tube installed in the landing gear strut
holders. It is extremely important to be sure that the antenna does not pass near any electronic
components, and that it is secured to prevent it from coming into contact with any moving parts
(especially the rotor blades).
If using a 72MHz receiver, you may also choose to install a base-loaded antenna to help reduce the
length of the antenna required for proper operation. We suggest using a Revolution Base-Loaded
Whip Antenna (RVO1010) as it can easily be mounted securely in the landing gear strut holders.
