gimbal control

Hi, I mounted a 120g camera on a brushless yuntai 2 axis gimbal.It is mostly balanced. When I turn on the power (5V USB),  the pitch axis stabilizes fine, but the roll axis doesn’t. Please see these two videos for explanation:brushless yuntai 2 axis gimbal - powered off: https://youtube.com/shorts/qSomVYpEpBcbrushless yuntai 2 axis gimbal - powered on (USB 5V): https://youtube.com/shorts/oU3yM9OY0fICan you tell me what to do about this? I don't need to control the gimbal, I just want it to stay…

Back to the activity again after 8 years.

Was involved with RC planes etc. making and flying since 2003. Entered into the field of autonomous flights in 2012 with the ArduPiot legacy board when learning C++ was kind of mandatory requirement to use that board. By 2017 had many successful flights using APM 2.5. After that had no time for the activity due to some personal reasons. Now back to the activity again as an old enthusiast, with SpeedyBee F405 WING. Therefore, your well wishes are required and occasional help will also be…

DJI Mini-style drone running ardupilot

I've had the idea for this quad for nearly a month, but have not been able to sort out how to execute it and hope I can get some ideas here.The goalThis project would aim to make a quad that has: Endurance: The DJI Mini 2 can fly for 20-30 minutesPortability: The Mini series is foldable and very compact, and while the style of folding the mini/mavics use is difficult to recreate, I want to have the drone compact and able to fit in a backpackAffordability: The quad shouldn't exceed US$500A…

Speedybee f405 Wing

Hi, I'm getting 5v across most of the servo rail except for s7 (3.7v), s5 (4.05v), and s8(bouncing around 350mV. The servos aren't working as expected when put in s3 and s4. If I just plug s3 in, I can get movement albeit not as much as I expected. I was going to try to use an external 5v supply from the esc but I can't find that option on the jumpers. Any ideas on how to stabilize it and why it wasn't already? I suck at soldering but I'm fairly certain I haven't shorted out and of the pads.…

Can You Identify the Type or Model of This Drone?

Hi Everyone, I have just joined this forum for the only purpose to see if anyone can help me find out what kind of drone was captured by my surveillance camera. Basically, there is a construction going on in my backyard (reason for the mess) and the back gate was removed. Since there is no gate now, I have used my mobile phone (connected to a laptop via USB and OBS was recording) as a security camera to record any night activity there. For a few seconds a drone appeared with poor visibility,…

Web Based Tuning Simulator for Arducopter PID Control Loops

I remember some years back there existed a web based turning simulator where numerical values such as P, I, D, IMAX, etc could be input along with the drone's mass.  The drone could then be flown vitually to visually look at how various tunes would fly (or not fly).   Does anyone remember this simultor or have a link?   I remember the creator was recruited by 3D robotics back when they were still developing the 3DR Solo.
