After the the APM2.52 flight controll board, we released 3DR Radio Telemetry recently, soon after, you can get a whole set of kits to make your Quadcopter. check them out.
The 3DR Radio Telemetry of 3D Robotics is an ideal module to set the remote sensing connection module between APM and ground station. It features small volume, cost effective, wider transmission range, and it allows us to do things that other radio modules can’t do.
Compared with other radio, this 3DR radio telemetry has the following merits:
1. Very small volume
2. Selectable operating frequency: 915MHZ 433HZ
3. Receiving sensitivity: -121 dBm
4. Transmission power :20 DBM (100 mw)
5. Transparent serial links
6. Air data transfer rate is as high as 250 KBPS
7. MAVLink frame protocol and status report
8. Frequency-hopping spread-spectrum (FHSS)
9. Adaptive Time Division Multiplex (TDM)
10. Support LBT and AFA
11. Configurable duty ratio
12. Built-in error correction code (can correct up to 25% of the data error)
13. Transmission range can reach miles with the small Omni-directional antenna
14. Use bilateral amplifier to gain greater scope
15. AT command deploys data transmission
16. RT command remotely deploys data transmission
17. Self- adapt to the flow control when used with APM
18. Based on HM – TRP wireless module, equipped with Si1000 8051 micro controller and the Si4432 radio module.
19. The Master collocates with long antenna and the Slave collocates with a short antenna to reduce the load of the aircraft.

Here is a short video of the first test flight of our new Quadcopter. After some modifications and debuging work, the quadcopter is diong quite well, it won’t be long before the craft be put on market.
