Just to give you an update:
Yesterday i did a 14,4km flight with the OpenLRS (telemetry off) and it worked fine (no fail safes).
Eagle Eye flying wing (1,6m) with 2x 3000mAh 3S
ImmersionRC DUO5800 v3 with 7,5turn Helical and ImmersionRC Tx 5.8Ghz 600mW with SPW
Turnigy 9XR with Hawkeye 1W OpenLRS (SRH771 antenna on the Tx, selfmade dipole on the Rx)
At first i was not sure, if i should continue the flight, because the picture quality was pretty bad from 4 to 9km.
When i reached 10km, the picture got better and i kept flying till 14445m. I needed to turn back, because of the battery voltage. On my way back the batteries died in ~4km distance, so i decided to land the plane on a field that was in line of sight and 3km away.
It worked perfectly and i picked up the plane by car. On my way to the field, i was also able to test the nice PMR radio beacon feature…it worked very well (although i already knew, where to go *g*).
The flight was done without telemetry or RSSI or autopilot, so i can not tell, how much RSSI was left in 14,4km, but as i will not need that much range anyway, i will try to reduce the OpenLRS output power next time.
We managed to do our first flights with the Flytron and Hawkeye OpenLRS systems.
Tx antenna: Diamond SRH771
Rx antenna: selfmade dipole
Sadly the Bixler 2 ran out of juice, so we stopped our test at a distance of 7km with an RSSI Value of ~90% which is pretty nice. Telemetry was off, Refreshrate 21Hz, 4800baud.
I also needed to stop my testflight with the flying wing, because it started to rain.
This time we turned telemetry on (only 100mW for telemetry available) and we had to increase the baud rate to 9600.
Both settings will decrease the maximum range.
The RSSI warning kicked in at only 1.5km and started to increase its beeps at 3km.
When i reached ~5km, the telemetry was beeping all the time and i finally saw many rain drops passing by, so i turned the plane around and flew back.
During that flight, i also recognized, that the OpenLRS tx is somehow distorting the 5.8GHz video.
It seems that it’s the cables of the FatShark and the groundrecorder that gets influenced by the OpenLRS (or of at least one of the hopping channels) and not the FPV receiver.
We will do more tests soon.
Here’s our new Channel Trailer to tease potential subscribers
Here are a few ‘deleted’ scenes from the last year. Unfortunately, the weather is still pretty bad here but we are preparing for the new season. New planes, new copters and new equip So stay tuned for some cool new stuff.
As the season hopefully starts soon, we ordered new RC stuff.
1x Flytron 433mhz Open LRS System (1W)
1x HawkEye 433 mhz Open LRS System (1W)
We hope to get even more RC range out of the OpenLRS systems, because right now in most cases it’s not the video link that limits us, its the RC range.
Most FPV gear is already optimized for the GoPro (Copter mounting options and BL-Gimbals), so I’m not sure, if the new HDR-AS100V is really an option for FPV, but it has some nice specs and good quality.
sorry that we didn’t manage to get some more videos online lately.
We were pretty busy with non fpv stuff and the weather wasn’t good at all.
I hope we will get some great weather and more time to fly in 2014.
