The Drone!
Got the whole thing printed, electronics assembled, parts as per the BOM. I have followed the blog as best I can, but maybe there is something missing or I don’t understand?
I can configure everything in Betaflight, and bench run the motors when connected to Betaflight but that’s it.
The receiver is giving all of the right LED indicators for being bound to the transmitter but when the drone is run as a stand-alone absolutely nothing happens other than the electronics power up. It completely ignores the transmitter no matter what combination of switch positions I try.
Has anyone got their drone running and if so can you let those of us struggling know exactly what settings you have used in Betaflight and if necessary on the FS-i6 transmitter?
I don’t yet know if I have some bad electronics, a bad transmitter, or a bad config. My young son wants to have a play and I keep having to disappoint him. I have tried a second receiver as well. No improvement. 😥
I have used full ESD precautions throughout handling the electronics.
What have I missed?

Re: The Drone!
Go to your receiver tab in betaflight. Are your values changing when you use the transmitter?
Re: The Drone!
Nope. That’s why I’m suspicious of it. Binding LED shows OK - steady when Tx is on, slow flash when off. So there’s a signal at least. I may just have to buy a second Tx - but they aren’t hugely cheap.
Comms is set for SBUS, with appropriate receiver type.
Aux 1 for Arm
Tx Aux switch set for either SWA or SWB but makes no difference.
Rx wired correctly,
PPM off or on makes no difference.
UART 1 set for Analogue Rx - but tried others - as per the Prusa Blog.
Tried it with and without external power - it needs a battery connected to run up the prop motors.
It could be the HGLRC fly tower itself. It has good LEDs and I can talk to it via USB in terms of firmware updates, gyro cal, motor drive etc, just no response at all on screen or on the drone regardless of Tx adjustments.
If I had a baseline set of configuration that are known ‘good’ I have something to work from. I’m betting that it’s something simple. This stuff looks to be pretty much plug and play. The printing part on the Prusa Mk3 was simple 😀

Ok so you have a good link between TX and RX. But the receiver tab won't show the movement on the sticks until you tell betaflight which port the RX is on. There's the other tab called Ports where you set which UART port has the RX on it, did you do that?
I always trip over this step when setting up a new drone/receiver. You're very close!
Re: The Drone!
Analogue Rx set ‘on’ for UART1 as suggested - tried 2 & 3 just for good measure.
USB input is set at default and not altered - I think the flight software won’t connect to the flight controller if I disable it.
Soldering iron now fused to can’t change any hardware... aaarghh! New element arriving next week.
I followed the instructions in the blog very carefully and it looked so easy!
I’ll try connecting the ppm signal wire once I can solder again and see what (if anything) that does. The Flysky FS-i6 needs setting up out of the box (that wasn’t covered in the blog) as various OEM defaults are not enabled by default and need to be. The Aux settings were all completely off or set to use the wrong switches.
RE: The Drone!
I still haven’t got mine working either. It just suddenly surges the power, lifts off and promptly cut its power. The project guide is as above flawed as it seems to be a mish-mash of bits that (for me anyway) don’t want to play nicely together. The images and supporting shopping instructions don’t match up. I’ll get back to it when I have more time.
The printing was the easy part.....everything came out just right.
RE: The Drone!
I built the drone half year ago. It flies nice, but flying it really requires some practise. The building tutorial is a bit fast and in some points not very detailed. What I found during assembly is a discrapency between bill of material and the video guide. Bill of material contains FlySky components, which use IBUS, not SBUS as it is shown in the video. Also one necessary step was missing. To test the transmitter with Betaflight you have to connect the battery to drone, it does not work only with USB power. That might be the answer to the original post.
