3DR telemetry no longer supported by 3DR....options?

I have been using the 915mhz telemetry v2 units with my Pixhawk for a while now.  One of them is not giving the range that it used to and I need a replacement.

I varified the range with the use of my Fighting Walrus iDrone Link and one unit is getting about 100m range while the other is getting good signal to where my hexacopter is just a spec in the distance.

Problem 1:

I can not get hold of Fighting Walrus any more.  They have not answered my emails since about October of 2015.  I am assuming they are no longer active? (also no updates to their iOS app for almost a year)

Problem 2:

3DR are no longer making their 900 or 433 telemetry units. (verified vie an email to them)

"Hello Justin,

Thank you for contacting 3DRobotics customer service.

We apologize for the inconvenience. Unfortunately, we do not have the Telemetry available anymore since they have been discontinued, both the 915 and 433."

I am using a Nexus 7 v2 Tablet with the Tower App (great app by the way)


Other than the $250 long range 900mhz kits (I don't need/am not allowed to use super long range) or $10 knock 3DR off kits from China (gamble as to whether you get a good one/no warranty), what options are there that are "PnP" ?

I am using a Taranis Plus TX with x8r RX and could use that telemetry but then there is no way to load missions in the field.

Thanks for input

I'll also note that jDrones, another long-time supporter of Ardupilot, is selling an alternative radio system.  In an attractive case no less!


Rob, thanks for the suggestion and I'm sure they are great but my original question was 

Other than the $250 long range 900mhz kits (I don't need/am not allowed to use super long range) or $10 3DR knock off kits from China (gamble as to whether you get a good one/no warranty), what options are there that are "PnP" ?

 $260 is a lot to spend for a hexacopter that I must still be able to see whilst flying (stupid FAA)


Thx for the link. In Europe only a 433 MHz version can be used. Should request that to JDrones.

I do agree with you. We used 3dr for 2 years starting a drone business, now what?
Arsov boards looks great, but what will be the future? This may not apply to Arsov, but great products made by small companies that disappear as fast as they came out is common.
On the other side, professionnal needs quite differ from Solo or Inspire 1. Solo sdk... let us know how to connect, and provide the dedicated connector?

If you read my comments you will see that you don't need to spend $250. You get plenty of range by buying a single RFD900 (~$90-$100) for the ground station, and a $15-$20 cheap 100mw china module for the aircraft. I get over a mile and retain 90% rssi or higher. 

Hi Chris. Just a note to give you my appreciation for the support you've given to the community - there's been a lot of altruism and business experimentation on your part; lots of scut work and community building... lots of risk taking. You answering questions personally here is a sign of your dedication. A note of encouragement : although not perfect, I know first hand that the 3DR DIY parts are more reliable than the clones and I'd be in a bind if they disappeared. Safety and assured airworthiness has a $ cost, and until it is well-understood, people will experiment with cheap clones. But when it catches on - and it necessarily will (perhaps requiring enforcement by the FAA or Transport Canada up here) - 3DR will be rewarded. In short, thanks, and don't let 3DR change too much please.

A question : why have you been waiting so long to launch the Pixhawk2? To give the Solo some room to grow?

Thanks, Frederic. We decided not to release the Pixhawk 2 as a stand-alone, since it required too many external components to work as well outside of Solo as it does in it (not just the all the IO interfaces but also a stand-alone SoloLink). Instead, we're going to release a smaller Pixhawk, and then quickly move to next-generation architectures. The 32-bit era is coming to an end, and it's time to move in more revolutionary, not evolutionary ways. 

Chris, really amazing.

Would you have some links/tutorials on how to implement flying over rfd with xbox controller ?

Thanks in advance

Paul, that works right out of the box. Both Mission Planner (Windows) and APM Planner (Mac) support game controllers, and I use the Xbox ones myself.  Just load this driver

Hi Paul,

All the info on how to do it is online in the wiki (this is how I learned):


One of these days I'll be sure to document better video of how well it works.

Many thank's Chris to put in hobbyst people this technology that was exclusively professional users (for cost), now we have many choices to follow with our vicious-hobby, possible that you open the door; my admiration how, with an open source, no secrets you can develop an important company helping others and having profits :O and still participating in this forum as other of Us; the best luck in this new step I'm shure you are going to have it. :D

If you download the latest beta of Mission Planner you can see the radio configuration tab is now labeled as Sik Radio.
