That’s great information!
I can add that the Aikon ak32pin 35A is good down to about 5.3-5.4v. (based on my onboard voltage sensor, which might not be accurate).
But, I’m a little upset that the product literature specifically says it supports current over telemetry, when it really doesn’t… After a month of emailing them almost daily, I finally got someone from aikon to reply and say, no, their published specs are wrong! urg… But, it is good down to a low voltage.
Hmmm… I will order one unit of this Aikon model for testing. Do you know the exact weight of it?
No… Probably relatively heavy, though… It has a thick PCB, and big current sensor resistor. I’ve only got one and it’s installed, so I can’t weigh it.
One more resource for those who wants to assembly one of this:
Regards!
WOW- That is the BEST video I have ever seen! Amazing work on both the copter design and assembly video.

Thanks, man… don’t forget to leave your “like” there 
!
very nice seems like a lot of modeling work for me.
but were are the real flight videos and pictures?
I’m only testing in hovering at the moment.
I will do some real flight tests soon. I’m solving some communication issues with XBee radio…
Regards!
i am not familiar with XBee, but if this is only a serial telemetry why not save some grams and use the frsky r9 or dragonlink?
I’m using R9 MM telemetry. The XBee is for communication with the companion computer (NanoPi NEO Air). Btw, I’d like to find a way to receive the R9 MM telemetry on the Taranis and on a ground station as well… 
Hi Ricardo, your 3D animation is awesome. May I know your email address? Best regards…
This is amazing. May I kindly ask if we could chat via FB Messenger a while? I do have an industry project for which I need a sub250 with long flight time. It shall carry a small Thermal Cam. You can reach me with support@flyingmachines.de or FlyingMachines.de on Facebook.
Okay. I’ve just sent you an e-mail. Regards!
Hi Hans. May I kindly ask if we could chat through FB Messenger about this sub250? I have a industry project for such kind of drone an would need some support. Bye Chris, FlyingMachines
Hi, i have a nano quad with F4 and arducopter. 2" props 1104 7500KV motors, lipo 2s 450, frame 90mm. Can you share the pids for quad like this dimension?
Thanks!
Awesome Job guys, what’s the furthest range for communication with the micro drones and what’s the average weight of the communication gear the drone carries. I’ve got a sub 250g off the shelf drone fitted with sensors but controlled manually, I want to move over to making it relatively automated.

Hi nightowl, we are using ESP8266 for telemetry communication, its very cheap and with MAVESP firmware its very easy to use and configure, Andrew Tridgell made a wonderfull work for it and Ardupilot, have a look here https://ardupilot.org/copter/docs/common-esp8266-telemetry.html
Sure its integrated antenna its not a champion for a great range, but have a look at this range test to have a better idea https://ardupilot.org/copter/docs/common-esp8266-telemetry.html
Depending on the type of automated mission you are planning to do maybe you could rely on auto mode, failsafe mode, and maybe you could accept to have the drone out of GCS communication range if you prepare very carefully your auto mission.
I use a crossfire nano, and it weighs about 1.5 grams w/ the antenna. It does RC control and mavlink telemetry.
I have flown over 6 kilometers away w/out any problem. Battery will definitely be your limit. People with larger vehicles fly this system 20+km.
I use the ESP8266 radios also and on the same mini quad Frsky R9 Rx. The R9MM is some grams. Not the range of Crossfire I don’t think but for these small craft there really isn’t a use case for long range. I have run Auto Missions at some distance but just for testing purposes.
