"What brand of motor is it? Motor specs usually don't say a specific voltage, rather the number of cells, like 3S or 4S. "
"Right. I was relating a little history of why we got rid of the smart part of the only smart batteries that existed when this technology was new. Also, why you wouldn't want to use an off-the-shelf cordless tool pack, which do cut off and, at…"
"We used to make our battery packs out of Milwaukee V28 batteries by disassembling them, discarding the "smarts", and saving just the 7 individual cells to wire into 3s to 7s packs. The reason for discarding the electronics was fear that they would…"
"Jeremy, yes I'm using SiK firmware versions from 1.5 to 1.12 all communicating nicely. By that, I mean I might have an aircraft with 1.12 communicating with a ground station running 1.5 or some other version in between, or vice versa. I'm…"
"Jeremy, my experience has been that the RFD900 works ok with ECC on, but the RFD900+ doesn't. Seppo told me that the 900+ just couldn't handle the overhead of ECC because of other added features. ECC has to be set the same on both ends for the…"
"Polly,
I have a ton of the 3DR and Hobby King radios here collecting dust (I switched to RD900+ and RD900u). I never trusted the Hobby Kings after looking at one under a magnifying glass. If you send me a picture of your old 3DR radio, I'd be…"

"What's Jordi doing? Anyone know the circumstances of his leaving shortly after the big venture?"
"I feel bad for the "before VC" 3DR staff and the DIY community they served and that served them. 3DR had a good thing going and were doing quite well. They were doing what they had the core competency to do."
"We have been using RFD900 and RFD900+ radios on the ground stations and RFD900U radios on the hexacopters for some time now. We have never had any problems with either. The RFD800Us are so small and light that you can tuck them up inside the…"
"Hello Shyam, et al.,
I would simply like to create Arduino code to emulate MAVLink messages sent to a FLIR Vue Pro camera to write to EXIF metadata. My understanding is that the camera does not send MAVLink messages, rather just listens for them…"

"Marc,
Yes, you have to turn off ECC on both.

"Enes,
I don't know if it relates to your problem, but I found that my RFD900+ radios will not work with either my RFD900 or my 3DR radios unless I turn off ECC. With ECC disabled, they all work together just fine.

"If anyone is in a bind and wanting authentic 3DR V2 900 MHz radios, I have some spare sets that I'm willing to part with. These are radio pairs, purchased from 3DR - 2 radios with cables and antennas, still in their original packaging, unopened. …"
"Seppo,
Is there a US distributor for the RFD-900U?

"Jeremy,
You have to disable ECC on both modems.
The NetIDs have to be the same, but NodeID is for when one radio (say the aircraft's) is communicating with more than one other radio (say multiple ground stations). In which case, one has to be the…"

"Hi Jeremy,
The 3dr modems have ECC enabled by default. I found that the 900+ will not connect with either the RFD900 or 3dr modems if ECC in enabled, no matter what version the firmware. Here is Seppo's reply on that:
Hi Don,
There has been a bit…"
