After few months of patience I was finally able to order the V3 version from Dragon Link web site last night. They finally have a new stock!
I would be interested in hearing from others who have used Dragon Link before or any other long distance TX/RX combo such as TBS Cross fire etc. Why you prefer the others etc.
My main interest in V3 version is because it supports Telemetry (50KM), works with mission planner/Pixhawk, they even have a OSD solution as well now.
I would be interested in hearing if someone knows a better product than Dragon Link.
This is not off the shelf and requires DIY skills but it has better Mavlink telemetry performance than Dragonlink V3 (thus far I think).
Of course you really should be a licensed ham to operate a 1W 433 transmitter in the US. But that also applies to Dragon Link's 1.5W new RX units. Though I think these are a long way down the list of RF problems in out airspace.
Yes, you need a ham radio license to operate TX over 1W in USA. Basic ham radio technician license qualifies you.
The Hobbyking Orange Mod looks pretty interesting. Thanks for sharing. I may give it a shot. It is almost 1/3 the price of Dragon link. I guess the only advantage of Dragon Link that it works right off the shelf with stock antennas (No Yagi required).
Dragon Link V3 is arriving tomorrow. Let me test it first than we will have a bench mark to compare with.
