Gimbal and Controller

Since I've built a F450 I decided that I need a smaller gimbal then the Nex sized gimbal I have on my T810 hexacopter, I found a cheap gimbal on Ebay thet costed $70. The add says that it's a HIFLY 3 Axis Gopro gimbal but it doesn't look as other HIFLY gimbals I've seen.

I'm using a STorM32 gimbal with it, `I've only done a quick PID tuning and I don't have a proper gimbal mount yet that fits the F450 so it was mounted with Velcro tape during the first test. Works pretty ok for a Gombal + controller costing $100. Will do a proper PID tuning as soon as I can mount the gimbal properly.
