    Yet another "will my build even fly" thread.

    I build one F450 based quadcopter that came in a kit and now trying to build a F330 based quadcopter on my own. Aside from the usual mandatory parts, the copter is supposed to carry a Raspberry Pi with an LTE shield and a gimbal, both of them adding some weight. The specs are Standard F330...

    Why do some gimbals need balancing and others don't?

    I am building a 2-axis gimbal using a SimpleBGC. The motor for the roll axis moves one arm which holds the motor for the tilt axis and the attached camera module. Of course, this makes the roll axis unbalanced and puts high load on the roll axis motor which gets quite hot in the process. After...

    LiDAR based altitude sensors - Looking for further information and experiences

    Hello, and sorry, these are a lot of questions in one thread, but it's hard to get an answer to them. I'm not too happy with the imprecise altitude measurements of my Pixhawk internal altimeter and therefore planning on mounting a laser range finder below my drone. However, there are a lot of...

    How to reliably measure current battery level of a DIY drone?

    Hello, I'm building an autonomous drone with a Pixhawk and a Raspberry Pi on a F450 chassis, which starts and returns to it's home base by itself. For this project, I need to have a good estimate of the battery level. So far, I learned that the flight controller usually assumes a starting...

    Increase hovering stability - What can I do?

    Hello, I just built my first DIY quadcopter using an F500 frame. It uses a (vibration dampened) Pixhawk 2.4.8 controller and a normal m8n GPS. Maybe I had false assumptions, but I'm shocked at the high instability when hovering at a stationary point. It sways around like it's drunk, sometimes...

    Gimbal controller confusion

    Hello, I'm trying to build a gimbal for a custom build camera module and currently searching for a gimbal controller. The controller will later be autonomously operated via a PixHawk1 running Ardupilot, not via a remote. The gimbal will have 2 axes and the camera module has the dimensions of a...

    Tarot Gimbal (TL3T05) wont stabilize when powered on.

    Hello, I have trouble getting a Tarot TL3T05 gimbal to work. When powered on, it should assume it's default position (camera facing frontal) and stabilize this position against drone movement, just like any other gimbal. Unfortunately, it never reaches that position. It always goes into a...
