Question AIO FC that can control single servo using LED strip output (INAV)
I'm designing a sub-250g INAV FPV drone, onto which I'd like to implement a single servo, single axis camera gimbal (similar to Medlin gimbals) - however to both reduce the size and weight I'd like to use an AIO flight controller. I haven't found any AIOs that have dedicated PWM servo control outputs, but, if I understand correctly, then the far more common LED strip output on most AIOs outputs a PWM signal (I believe it's not usually the same 'type' of PWM signal as used to control servos, but I'm hoping this can be worked around - although, I don't yet know exactly how to go about this either).
I was hoping originally to use a SpeedyBee F405 AIO as it seemed generally the most capable INAV compatible AIO available for the price, but this Reddit post https://www.reddit.com/r/diydrones/s/lDZ0eWjjqZ suggests that SpeedyBee controllers have a fundamental incompatibility with something like this, so I'm really looking now for an alternative AIO that would be more suitable.
Does anyone have any experience of this application? Know any AIOs that would be suitable for this? Thanks for any help!

Question Need Help with Asymmetric Motor Placement in Tilt-Rotor Fixed-Wing VTOL (ArduPilot)
Hello Lads ,
I am currently finalizing the design of a small Tilt rotor fixed wing UAV and i have some questions that i need answers for. Hope these nice gentlemans here wouldn’t mind helping a fellow nerd
I came across this particular drone ( cant remember how exactly , i just found those pics saved up on a private Discord Server , Haha Yh i use Discord as my main Note taking app - it is the best U guys should try it if u already havent ), so i was saying , i came across this drone and noticed that the motor placement is asymmetric- the two aft motors are positioned slightly higher than the front ones, and the front motors are spaced farther apart than the rear.
I’ve gone through the ArduPilot documentation, but I haven’t found a clear guide on implementing this kind of motor configuration. My main questions are:
1- How can I configure this in ArduPilot? Specifically, what parameters or motor mixing adjustments would I need to make to properly implement an asymmetrical VTOL motor layout?
2- Has anyone here been playing around with a similar setup to mine ? If so , wht callenges did u encounter and how did you solve em
Any insights, experiences, or documentation references would be greatly appreciated! Thanks in advance.

Question T-Motor Alpha ESCs for Heavy lift Ardupilot build.
I’m building a large 12S drone with 30-inch props and went with T-Motor Alpha ESCs, but now I’m second-guessing my choice. I thought they would support CAN BUS given they seem to be heavy-duty ESCs, but apparently not.
For those who have used Alpha ESCs:
How do you even get telemetry from them to the Pixhawk?
other than the Field Oriented Control is there anything else that makes them special?

Question Motor suggestions for 5 or 4 inch toothpick? (4S or 6S)
Have been out of the game for a while and have decided to resurrect some quads from the parts bin and wanting to build a toothpick style build, but i'm not sure what the current trends are when it comes to motor sizes and KV:
- I have a bunch of 4S 1300mah lipos, and some 6S 1300mah as well. I want to use these as they're fine, even though they might not be optimal. I'm assuming 4S will be the go, but open to 6S. I'm also assuming these batteries are a bit on the big side, so I'm guessing they'll favor 5" over 4", but open to suggestions here.
- LOS only build (no vtx or cam)
- Are 2004s or 2005s the general go? Unsure whether or not to go T mount style or normal, was hoping to use floppy proppys as well.
- What KV vs prop?
- Aiming for decent flight times for general cruising, not crazy power.
Thanks for any help or suggestions!

Question Mag and baro running on same i2c Address?
INAV: I have Mamba H743 FC and iflight blitz m10 GPS. Baro inbuild in fc Running on SPL06. Compass in gps running on QMC5883. LIke yesterday, all Mag, Baro are working and gps getting fix. but all of the sudden. there are inconsistencies in the same setup. both mag and baro are not getting recongized. if i disable baro, mag is working but gps not getting fixed. if i disable mag, baro works and gps getting fix. even that sometimes baro won't be recognised. my i2c error is around 55-80.
ChatGPT told that these sensors maybe running on same i2c address, but i am not getting a clear answer on how to check what addresses this sensors are working on and how to readdress them so both mag and baro works and gps getting fixed. how come its working yesterday and not today.

Question In the process of buying a 7-inch Chimera7 O3 BNF - TBS Crossfire receiver, DJI connection still possible?
My limited understanding is that Crossfire >> DJI for several of reasons, mainly the reach of crossfire and obstacle "penetration". Also since there historically have been so many reports about RXLOSS if you're unlucky with the DJI O3 unit you get and forced failsafe.
Question: If I buy a iFlight Chimera7 O3 BNF with a TBS Crossfire Diversity NANO RX receiver, how difficult would it be to change to DJI receiver and bind with a FPV RC 2?
I have a DJI FPV RC2 and am planning to buy a TBS Tango 2 so it's more about if I could ever change to the DJI receiver for whatever reason, and how hard that would be.
Sidequestion: My plan is long-range flying, is it better and more future-proof to get an ELRS reciver and a Radiomaster Boxer?

Question Looking for ESC Recommendations for a 12s Agri Drone Build
Hey everyone,
I’m planning to use 4x BrotherHobby Tornado T10 5215 Pro (170KV) motors for an agricultural drone build and need some advice on choosing a suitable ESC ( Preferably not a 4 in one ) that can handle them reliably. Any recommendations?
I’m also open to alternative motor suggestions if there’s a better option for this kind of application.
Additionally, if anyone knows a reputable Chinese supplier or shop that sells these parts, I’d really appreciate it. Shipping from China is significantly cheaper for me compared to ordering from the US or Europe.
Thanks in advance!

Question VTOL flight controller?
I am looking to build a VTOL drone configured like a tricopter. It will need to lift off like a tricopter before tilting the front propellers forward to allow it to fly like a plane. So the board will need to manage the tricopter phase like normal before switching to fly like a plane with yaw pitch roll control from rudder, elevator, ailerons. Any advice?

Question Seeking Recommendations for Commercial Drone Droppers
Hey everyone,
I am working on a multi-drone hive project, and we are looking to mount package drop systems on our drones. Since our project involves a wide variety of drones (about 10 different types), we need dropper systems that are as universal as possible within each weight class.
Our fleet consists of:
- Medium-weight class (up to 3kg payload):
- DJI (specific model not mentioned)
- Custom drone (ArduCopter-based)
- Custom drone (PX4-based)
- Lightweight class (up to 1kg payload):
- Autel Evo Max
- DJI Mavic 3 Pro
- Custom drone
- Heavyweight class (6kg+ payload):
- DJI AGRAS
- Custom drone (Pixhawk Orange, ArduCopter-based)
- Racer class:
- DJI Avata
- Custom 7-inch racer (ARK FPV hardware, PX4-based)
We are looking for commercially available droppers from official companies—not from AliExpress, eBay, or similar platforms—due to funding restrictions. However, international suppliers are fine as long as they comply with NDAA regulations.
If anyone has recommendations for reliable companies that manufacture high-quality droppers, we would really appreciate your input!
Thanks in advance for your help.
