3 motors or 4 motors for RED

jhonalovej

Im about to build a Gimbal that support RED. Some people say ipower 5208 180T (3 motors) can support red. I saw some videos as well, but I dont think its reliable since the motors are working very hard to balance the heavy camera.

here are them two options i would like you fellas help me out.

1. using 3 ipower 8017-120T motors
2 using 2 ipower 5209 120T and 2 ipower 5208 180T (any diagrams how to wire 2 motors along the same axis ??)

so which way is more convinient for heavy cameras like RED?

Thanx

2 tilt motors are better easier to balance but 8017 motors are heavy. you can lift more with 8017 and 2 tilt 5208 for sure.

If you plan to use YAW, you should read this:-

tnx AOPEN, any diagram or how to setup two motors on tilt with the controller board ??

Andy, does it mean i need an extra 2 axis controller board ?
thx

Y servo cable connecting the 2 tilt motors they must turning in the same direction. Auto detect one at a time the should be both reversed or not reversed other wise you will need to switch wires around.

that's the exact frame i have, what if they dont sync perfectly the same, this may cause a problem. thenx for pointing that out, I'll give it a try and will post the build.

Jhona, The setup with 2 boards does not work, unless you plan to use one board with the small Yaw Ext board ... but there may be an issue with big amps.

Our solution is to go with the new big amp board with all 3 axis on it

you mean this

thnx andi

they have awsome looking gimbals with 4 motors, I'm not sure they use Alexmos board...the build is really nice. eventho they use 4 motors on that gimbal, the fact that it doesn't support RED cams...

i forgot to mention you need to mach the poles up as well! I guess you may have mounted the gimbal motor wrong

jhonalovej

the gimbal is almost assembled,.. the gimal is this for your info

besides, what do you mean the '...mach the poles up...' ??

AOPEN3434

that is my gimbal I AM RESPONSIBLE FOR THE DESIGN. FAMOUS HOBBY DOS THE MASS PRODUCTION.

the motors must start at the same point on the same pole.

AOPEN3434

thanks for you support!

jhonalovej

Oh okay nice to have you around...oh by the way the frame design is really nice...i cannot default it anyway :)

so how do i make the motors start at the same point on the same pole....am sorry i dont just understand the terms :)

AOPEN3434

remove one side of the motor from the frame on the tilt and rotate 90 degrees bolt togeter. if you still having problems pitch is not ballanced

Anyone running the 8108-150 motors for Roll and Yaw, and 5208-200 (2 of them) for pitch? I have set it all up with Red Scarlet, Side handle, and sigma 18-35mm f:1.8. Camera with everything weighs 8.8 lbs. I have balanced Pitch and Roll perfectly but struggling a little with YAW. I'm also struggling a ton with calibration and PID/Motor settings for the rig. I have begun video of all my efforts and findings, I will post soon. Any suggestions on Sensor mounting possibly too? Will post all my findings as they come.

suggest you watch the tuning video
