Update: This brushless gimbal is completely spanked and in the bin! The problem with the pitch bearing meant that it never fully calibrated as there wasn’t enough free movement. I’ve since used the gimbal as a template to create an improved version, with proper bearings, and had it cut from 3mm G10 fibreglass sheet.
Thoughts on the brushless gimbal
The HobbyKing brushless gimbal is so-so. The parts didn’t fit together too well and I had to hack the camera tray to give it free pitch movement. The bearing on the pitch axis has a lot of resistance and I think it’s a little too stiff. However, the camera is a little top heavy on that axis, which isn’t helping the gimbal level out.
The gimbal controller
The gimbal controller was from ElectriFlite and seems solid enough. This is my second controller, the first being a nasty Chinese fake off eBay that never worked!
The BruGi firmware is a dream. The only change I’ve made to the default settings is to reduce the PWM max by a tad. You can hear the motors humming in the video, so the setup is not perfect, but out of the box this is pretty amazing. Only a few small tweaks to the settings to finish it off.
