"I really like your setup and the yaw mechanism.
Are you using PLA or ABS?
How is the printer Z-axis oriented?
Are you using anything else to strengthen the print? Some post-processing? "

I built a custom testing rig out of some plywood sticks and these kind of elastic cords:There is just enough clearance for 7 inch props and the quad is free to rotate around one axis (Y or roll in the video). I can easily change the free axis as the…
"I like your yaw system. I guess you went for a tri to save weight, right? You might end up with more weight than if you went for a X quad because of the servo (which alone is 20-30% of the weight of an extra motor), the yaw linkages, extra CF tubing…"
"@FernRF: Thanks a lot for the details. You got me hoping I can revive the 4463 project.
Can you post some video with the bitrate at this bitrate?"
Can you post some video with the bitrate at this bitrate?"
"@FernRF Actually the datasheet says the max is 500k symbols per second. With 4FSK a symbol is 2 bits so a max rate of 1Mbps. This is well within the specs.
The RX sensitivity @1Mbps is -88dBm which is very usable.
Regarding the fifo, I was curious…"

"@FernRF: thanks a lot for the hint PA. I will definitely check out your code. It might be what you mention, maybe I got the wrong frequency modules or I had the wrong configuration - even though I doubt it, I was measuring with a SDR and spot on 433…"
"@FernRF - do you happen to know what version they are?
I tried to get 2 of them to work for 3 months without success. They got unstable at higher power levels (>50mW) and the power rail got a lot of noise. My guess is that the power amplifier draws…"

"This looks great! Which module did you use? Is it the RF4463F30 one?"
"@Ted - somehow I missed your question... The gimbal pitch is not balanced as it relies on the camera being light. It can take a slightly heavier camera or the RPI+Lens but I didn't test it. The motors are definitely strong enough to move more…"
Here is the first test of my custom RC that will complement my custom FC and quad.It uses a Raspberry Pi, 2x 2.4Ghz wifi cards for video streaming, a 433Mhz connection to control the quad and a 5.8Ghz wifi card to send the video to an android…
"I intend to buy these and solder flexible 26AWG silicon cables to it.
Fitting the pi zero on the gimbal would make it bigger and it would need more space to rotate freely. This is an issue on the mini quad I'm building."

I ordered these motors and this gimbal controller some time ago to make a gimbal for the Raspberry Pi camera. This weekend I managed to model, print and test it.It weights ~65 grams, is very compact and fits perfectly on my new quad (more on this…
"@Patrick - absolutely no interference so far. I tested with an UBLOX Neo6 GPS module and even with the new camera on I still have a strong fix. I still have to post the measurement data but didn't have time to get to it.
@Alex, I thought about…"

(You can check the progress (and a copy of this post) on my blog.)Finally, after some DHL delivery trouble the boards arrived.After watching a few tutorials I immediately tried soldering the most difficult part – the MPU9250 chip. Turns out – if you…
