Been testing a brushless gimbal on my quad, it's an own-design laser-cut Liteply gimbal which uses a Foxtech AIO (Martinez) controller ($50) and Foxtech 2208-70kv motors ($21). Information is a little hard to find on the controller and tuning of these things a little tricky but so far the results have been very encouraging.
The gimbal was laser cut from 2.5mm Liteply but needed some reinforcement to prevent flex so this is now version 3.1 :)
3mm or 4mm might be a little better in the stiffness dept. but this is not bad at all. It's also really light at less than 35g for the ply parts!
Camera is one of the new 1080p Mobius Camera's which is pretty amazing for the price of $70. just the colours are a bit saturated but that will be sorted out with later firmwares.
A very short video flying above my Johannesburg suburb showing the fantastic stabilization (Note: this is only 720p and I tried to keep the upload size small with a low bitrate, Youtube also takes some of the quality away):
