Hello,
I designed the Radius Camera Mounts to have the same ultra-smooth drive and motion on the pitch axis as they do on the roll axis. I have chosen high-spec helicopter cyclic servos with 0.09 and 9.3Kgs. There is a huge ratio between the servo and camera rotation axis, meaning the servo resolution is multiplied many times.
I can't help but think the pitch axis is even more important than the roll for cameras with large lenses - thats a fair bit of weight to control smoothly. Dampers on the camera axis are not an option IMHO as they make the servos work too hard.
Pneumatic shock absorbers should only be for landing legs ;)
My very next project is a 360 pano upgrade that will be a direct fit between the Radius mounts and the CarbonCore multicopter frames. ;)

I was wanting to find a site from where i can buy something like this shown in the image. From where can i order the pulley and belt as a kit ???
Hey Ramesh, Im far from an expert, but i do know that a geared drive camera mount will be more jerky than a belt driven.
Also digital servos aren't as smooth as analog servos.
My mount seems to work nicely, havent tested it out with an slr yet.
Iv been thinking if its too jerky, a little pneumatic shock absorber would smooth things out quite a bit, but would make response time slower. I like smooth over quick.
But the next option up from the MKTR (www.photoshipone.com) iv got is the carboncore Mega radius

Gareth, need some serious advise. is it ok to use geared system for camera tilt servo system or would a belt system be better, I intend to put my Canon EOS 7D with 17-40L lens and total wt is 1.5 kg. My feeling is that with a geared system some sort of damper would be needed, where as with belt i would not need any damper. And what ever system u suggest, could i request u as to from where can i order the belt system or gear system. I have been on net whole day surfing and have failed to find a site which gives it as a kit, from the item to be mounted on servo to the pulley etc etc. Would be grateful. By the way, i am making the body of multi copter and the camera 2 axis mount totally on my own with Alluminum and G12 material in my hobby room. I very rarely go in for ready made products, and just love to construct from scratch, I have not owned a ARF plane or a flat out till today, 35 years into my hobby. I suddenly have this urge to get into multicopters, its all the cutting and sawing and sanding drilling that is fun at the end of the day, even if the overall cost exceeds at times more than the original cause of some stupid mistake one may make.
Hey Ramesh: Thank you for your kind words. I do what I do for people like you :)
Iv never seen the point of multiple people making the same mistakes. Its redundant!
The more I can help the community, the more Iv feel Iv helped and played my part!
Thanks again :)
OPEN SOURCE ALL THE WAY!
Gareth, this is really nice of u to post all the components and their specs of Octa Copter, Not many guys do that. I am also in the process of making octa, but then decided to go in for Hex, so that i can make it a folding type, and have capability of lifting 3 kg payload, which would be my EOS 7D with 17-40L lense and camera frame, and still have 30 to 40% reserve of power/thrust for maneuvering and quick exits. However since this is the first time i am getting into multi copters, i am first making a Quad with same arm lengths as i would for the Hex, learn from there and then get onto the Hex. I have already pre-ordered the APM2. So heres wishing u all the very best, and thanks for sharing, U are a true hobbiest to the last word.
I am using the Dlux 40amp ESC's. Nice esc's, though a bit bulky. I have them on a Mikrocopter Quad frame and Mk motors. Have the ArduMega 2560 installed. Flying nicely with the 0.55 install. Still tweaking the PI's abit, but very close.
Looks cool :) all the best for your build!
