Need help understanding Gimbals

Hi, I test flew my DJI f550 with NAZA m v2 and GPS yesterday. I am ready to put landing gear and a camera on it. I have been looking around at gimbals and mounts. I know the NAZA has ports for the gimbal axis but I am a bit confused on what does what. Will the NAZA stabilize the camera on the gimbal, or do I need a separate stabilization controller? From what I understand, the NAZA provides forward feed of the correction needed to a gimbal system (similar to what it does to stabilize the copter).

What are a few gimbals that will do what I want. I want something that is less expensive. Hopefully I can find something in the 100 - 250 range (I know the landing gear is more cost too). I have found a few that might work but just don't know enough about them yet. Here is one that I found that I think could work. http://www.rctimer.com/product_950.html. I don't mind doing something with integrated landing gear. I was planning to rig some home made landing gear.

The camera I will be putting on it a slightly different model, but same shape/size/weight/brand as this one: http://www.amazon.com/Samsung-SC-MX20-memory-camcorder-Optical/dp/B001FA1OQS


Thanks,

naza gimbal controller is for the old school (as of last winter) servo gimbals. brushless gimbals have or need a seperate BGC or brushless gimbal controler. honestly for that size airframe by the time you get done loading it down with what it takes you will get it over weight with a nex or the cam linked. If it was me, i'd shoot for a hero size gimbal that works well and get a hero3

I've played with this one and it's decent for the money

and in your price range. a 2 axis alexmos board is more than your budget, this one is martinez so it's less. martinez is a great way to start cause the sliders actively refresh the board instead of waiting till you hit write like alexmos so it makes it easy to learn on. it will never be as smooth as an alexmos board but that's the difference

Ok Thanks. So with this gimbal and a Go Pro Hero 3 I can fly the copter like normal and adjust the tilt via a slider or knob on my transmitter? This sounds perfect as I will be adding a video down link later on. Is there any recommended landing gear setup? I priced out some materials today and it may be better for me to get something off the shelf. I like the plain DJI gear, but noticed that a lot of the others have an integrated gimbal mount and a spot for batteries in the back for balance.

I have both the Alexmos - user ready for MS OS PCs as well as the Martinez which is an Arduino based open source project and therefore less expensive. The BGC board for Alexmos seems to be designed to handle larger brushless motors for larger cameras. The Martinez works best with smallest cameras and therefore smaller brushless motors. While the Alexmos was expected to work at the get go, out of the box, I had some initial challenges with it and found it easier to work with the open source Martinez even though that imposed a steep learning curve for someone with zero Arduino based experience. The ehobby ready to go BGC system is an improvement over the previous RCTimer BGC for GoPro because they were able to reduce the overall weight using a couple of carbon fiber parts...... the previous was all aluminum http://www.rctimer.com/product_872.html

A 2 axis servo gimbal system taps in to the existing Naza or WooKong IMU for MR attitude and only requires camera angle feedback by means of simple "brushed" rotary potentiometers inside of the servos...... Since the brushless camera gimbal motors have no pot position feedback, there is a need for a camera 2 or 3 axis IMU independent of the MR IMU. Therefore the Naza and WooKong gimbal control concept is on a dead end street. Also the positional control of the axis motors is uniquely different now......
