Q: receiver working not ideal, not smooth?

 

A: During communication, transmitter and receiver LED will flash fast and smoothly (no lost step). If 

the LED is flashing all right, there may be UHF transmitter power suppression on radio TX or 2.4G/72M 

receiver. 

 

Adjust UHF power to minimum; connect a servo to the 2.4G/72M receiver 

to test. 

Recommend  to  use  the  Repeater  station  mode,  with  a  vehicle  mounted 

antenna  extension  lines,  so  that  the  antenna  could  be  placed  far  from  the 

2.4G/72M receiver. 

Use  attached  foil  to  wrap  up  the  2.4G/72M 

receiver  (don’t  wrap  up  the 

antenna).  Or  use  foil  and  cardboard  to  make  a  18cm-radius  isolation  plate 

(isolation plate should be in contact with the antenna ground); which can isolate 

interference as well as improve the UHF signal effect. (Pictured at right) 

 

 

 

Q: Single-line PPM&RSSI Output to Arkbird OSD, the

 

aileron, elevator channel control is not 

corresponding. 

A:  single-line  transmission  1-6  channels  as  follows:  aileron,  elevator,  throttle,  direction  and  2 

auxiliary  channels.  If  no  corresponding,  please  change  the  servo  line  sequence,  or  set 

the radio TX’s 

PPM 1-6 channel as the above order. 

 

 

Attentions:

 

Be sure to read the Safety precautions of Arkbird equipment carefully: 

1. The Arkbird equipment can only be used for small aircraft model entertainment. Please do not install it 

in  the  camera  plane  which  may  fly  over  the  crowds.  Fly  should  be  done  in  open  field,  and  the  loss  of 

people and property caused by any accident should be prevented.   

2. The equipment must be installed and used according to requirements, and the check for the working 

condition should be done before every fly.   

3. Since  equipments  on  the  plane  and  any  other  electronics  are  not  completely  reliable,  you  should 

evaluate the product when using it, and should use it according to the related rules. The system provider 

is not responsible for any direct or indirect losses and effects caused by using the product.   

4. It  is  strictly  prohibited  to  open  this  tuner  near  the  gas  station,  or  place  where  the  radio  signal  is 

prohibited!
