Spektrum Install - for BVM KingCat
(for 9-ch or 7-ch receivers)

   
The Spektrum 9-channel Receiver and Flight Log is shown mounted on a 1/8"x1.5" plywood mount across fuse.  Mount is screwed under lip and attached with (4) #2 button-head screws.  Center of mount should be approximately 8.5" forward of canopy bolt hole.  Voltage regulator (if used) is velcro attached to bottom of mount under receiver. Standard KingCat wiring should reach new receiver location.  Attach receiver to mount with Velcro. Flight Log can be attached with 2-sided tape.
   
   

One remote receiver is shown mounted to 1/8”x1” ply mount similar to main receiver. Balsa block is glued to mount to hold antennas vertical. Approximate location is 2-2.5” forward of canopy bolt hole. (as shown)

   
   

Second Remote receiver (optional with 9-ch) is mounted on top of battery box in nosecone. A 24” “Spektrum” extension is required. A simple wood mount is fabricated to orient antennas laterally.

 This Spektrum installation has proven very successful in many flights at considerable distances. NO range problems have been found and very “LOW” numbers have been achieved on the Flight Log (i.e., all 4 antennas reading less than “20” with no fades or holds.

Note: BVM demo KingCats and BobCats have many successful flights on Spektrum 7 and 9 channel radios.
