Hey everyone,
I'm relatively new to FPV and stability gimbals, so bear with me if this seems like a newbie question.
I am looking at purchasing a 3 axis gimbal for a quadrotor I'm building. I wanted to incorporate a design with the gimbal mounted in front to prevent the propellers and landing gear from interfering with the image.
My concern is that the gimbals yaw axis will not be parallel with the vehicles yaw axis.
Does this matter, am I thinking all this through for nothing?
Please see my crude MS Paint drawing
Oh also... Can anyone recommend a good 3 axis gimbal?

Anybody? Is anyone running with a front mounted 3 axis gimbal?
Hi John,
I run with a 3-axis gimbal mounted off the copters yaw axis. I presume that you are concerned with the two axes not being in alignment rather than them being parallel (which they appear to be in your diagram). Unless the subject you are capturing is within a few feet away, any lateral movement of the camera due to the offset while yawing will not be noticeable. The gimbal will maintain the absolute orientation of the camera and the few inches of movement perpendicular to the direction that the camera is facing will barely change the perspective of the image at all.
Also, would you happen to have a sample video posted somewhere?
Yes. You are correct. I meant aligned. Thank you for responding.
So this is not an issue for you?
Hi John. James is correct. You have several factors working in your favor: Basically, while you're in the air there are no close-in objects to act as points of reference. Add to that the field of view is so incredibly large compared to the relatively short offset of the camera (in my case that's about 12 inches) that the off-center travel of the camera becomes imperceptible. Cheers!
