3DR Radio Maiden - Range Test

Yesterday I had the opportunity to test the 3DR Radio 900MHz.
On first impression I could see that he is much smaller and lighter than the Xbee.

I upgraded the firmware to v1.5 (the card that goes in the model airplane need a FTDI cable).

I made some ground tests with the default setting and noticed some delay by MissionPlanner. So I have disabled the option ECC and everything worked perfectly.

In flight test, I used a 7dBi patch antenna at the ground and flew up to 8km ( 4.8miles ) away and 2000m high and the 3DR Radio signal was in 90-94%.
Compared to the XBee system with the same patch antenna at that distance the signal was around 40-60%.

The settings I used were the image below. The only difference is the firmware v1.5.


I'm very happy with the 3DR Radio.


Thanks.

Thanks for correcting me.  I must have misread or misunderstood something somewhere.

Are there any plans for over-the-air firmware update?  That would be really slick for debugging.

Hi Sergio,

Can you tell what  7dBi patch antenna you are using. That range is fantastic!

Thanks,
