Packing 500mW of output power this V2 915Mhz Telemetry Radio Set allows you to link to a flight controller such as our HKPilot Mega or Multiwii AIO to a USB or Uart equipped device such as a computer, laptop or tablet supporting a USB connection (OTG). The new V2 radios, no longer have a separate Air/Ground module, as both transceivers can use Uart or USB connections and supports both modes. The Radio set not only lets you see live data, such as live GPS position overlaid on a map, system voltage, heading, waypoint navigation even artificial horizon and so much more. Using open source MAVlink based ground station software, you can even fly your aircraft with a joystick via your computer and update settings live! Or just use it for your DIY projects that needs a wireless Serial interface. This kit offers a great low price, longer range and superior performance. The system utilizes the 915MHz band and provides a full-duplex link using HopeRF's HM-TRP modules running custom, open source, firmware.

I'm overall very happy with these radios. I don't use them on the craft, only on the ground station. I've been using first gen 3DR radios and it's nice to actually have a plastic case. These are a drop in replacement for the 3DR versions, I literally unplugged my old radio from the ground station, plugged in the new radio and bamn it works. Range seems slightly improved compared to 3DR radios. If you don't need to go farther than 1km, these things are perfect.I bought 3 sets of these during the black friday deal. They are almost direct plug in replacement for 3DR radio. I have flown out about a mile and still had decent reception. Not sure if radio is putting out anymore power than 100mw but they work well.units received but the otg cord is defective. it has a broken connection inside. it works when cord it held a certain way, but as soon as it reverts back, then the connection is lost. Fixed by using a WORKING OTG plug.
