Not the same thing. The hardest thing to find in a roll and tilt axis camera gimbal is the pivot point of the roll axis. Most gimbals have the pivot point on the top. So the gimbal swing like a pendulum. Any yaw movement from the flying machine will disturb the roll stabilization.

This one has the roll axis pivoting at the lens center line. Assuming the edge of the roll cage is smooth on the bearings it is a very good design.

3 axis is too complicated for now. I believe it is more practical to start with a 2 axis first. The focus is on smooth video with roll and tilt. 3 axis is more for spherical panorama which is better achieved with a single main rotor helicopter and a bigger gimbal.

lol tony....

in this thread there are 4 people who have voice their opinion 2 said 3 axis and 2 said 2 axis..

majority

I agree that a good, smooth 2 axis is a great starting point and what should be focused on first.

Then a 3 axis

Yes the 2 axis needs to be smooth for video. The 3 axis needs to be quick for pano. So the design criteria is going to be slightly different.

Actually for a multi rotor it is pretty easy to just do a pirouette for pan.

In my opinion, a good approach is release early and iterate fast.
Don't try to make the perfect gimbal at one shot. Probably focus on smooth 2x...
On every iteration, look for feedback from your users/community.

BTW, my vote is also for nex5n compatible size.

How are you driving the roll axis? Is it direct geared? or some sort of a cable system?

I never said only people from this thread. I am sure there will be more who will want 2 axis. It would be real easy for him to see what the majority wants by posting the projected price of the 3 axis and a poll. Plus the 3 axis would have to include LG or a universal design that allows you to use diff LG. How much do you think that will jump the price up?

for a decent nex-5 or APC-S sized camera I'd be willing to pay $400-500


which if his 2 axis is $140 than that will be very do able.. I am looking forward to buying his 2 axis to try with my nex-5n when he is able to stretch his current version

If that looks good, i would love to buy a fairly light weight (compared to other options) 3 axis.

OP, thanks for asking for feedback and for providing at least a gopro gimbal at a competitive price

NEX 5

Width 115 mm from strap loop to strap loop.

CG is pretty center of camera from side to side.

Lens is off set to the left side (viewing from the back of the camera forward).

Lens center is approximate 35 mm from left side strap loop.

Oh and camera is 58 mm tall.

Tripod hole is under center line of lens.

Tripod hole is approximate 12 mm from back of camera.

Does this price include servos? I'm guessing not, but if so that's an amazing price.
