The £300 upgrades one radian to the 3-axis G-Lock system, so you would then have 2 spare radians to do with as you see fit. The G-Lock also has features over and above the Radian : it is not just a 3-axis upgrade.
The price for the BLD modules is not confirmed yet as we are waiting on manufacturing costs.
Hi are you saying that with this radiant upgrade I can use 1 radiant to control 3 servo motors? my understanding was that the tweeches that we currently get with radiant/servo motors is in the servo inability to respond fast enough in part for the slack in the gears inside the servo are the radiants going to be able to drive direct drive motors
Yes - 1 radian becomes a full 3-axis G-Lock controller.
The brushless driver modules are now in production and will connect to the G-Lock to drive brushless direct drive motors. The servo drives are also possible at the same time - so (for example) it could drive brushless on tilt+roll and a regular servo on pan.
The brushless motors are far quicker and more precise than servo motors : once you are used to brushless, you can spot a video stabilised with older type servos almost immediately.
I'll try to do something once this busy pre-release phase is behind me. Basically the G-Lock puts out all the motor drive information on a special bus called the High-Speed-Link (HSL). External modules pick up this information and then generate the output drive for the motor (eg servo pulse from the signal master or the 3-phase brushless motor drive from a BLD module). You can connect multiple modules to the HSL if you want - so the signal master can be driving the servo for Pan while a BLD module drives the tilt + roll brushless motors.
One thing I didn't expect though was just how much a brushless motor improved the pan on my cinestar mount. It virtually eliminated the oscillations against the 'o' rings which force the servo mount gain to be so low.
Hi John, I don't know if this thread is still alive but I'll give it a try. I'm looking at Alexmos vs. G-Lock for my BL gimbal. At the moment it's an all servo CS gimbal but the performance is not good enough. I've gotten some iPower GBM 5208-180 to run a BMPCC, RED(I know both are on the heavy side for this motor), EOS 5D and GH3. As I understand it I do not need the BLD module? But where would I then get the power for the motors? Do you have any videos or photos of the setup and so?
Whoa - I thought I put an answer on here last week but it seems to have gone !. Just to clarify, the G-Lock is the 'brain' with the IMU sensor and which sits on the camera tray. It can drive servos directly, but it needs BLD modules to drive brushless motors. One BLD module can drive 2 motors and they can be daisychained for 3-axis mounts. The motor power connects directly to the BLD modules.
