I have the baud set to 19200 but there is so much lag it's really bad.
I will try Unchecking more things
They are paired by having the same ID number, use the 3dr utility. Best to use a different one then they ship with in case. To my surprise I have met a few people with the 3dr radios at a popular flying park here in Brisbane, Australia. Probably as they are less than $40 a pair.
As for slow speeds, consider Air_Speed, default is 64k. This setting is inversely proportional to range. ECC doubles the amount of data you send but makes the link more reliable at distance.
I used the 3dr radios with stock antennas with the laptop sitting on the ground, modem stuck to the top of the screen to monitor my skywalker. Had no problems at 1.2km with this non ideal setup, no latency issues. Make sure mavlink option is not selected if you are not using an APM.
