This is looking very good indeed. I particularly like the soft start and stop to the 'follow' mode on the pan. Can the follow mode be tuned/adjusted in the configurator? I am getting very excited about this now. Hope you are close to pulling the trigger now. Seems like I need to invest in a brushless pan conversion though. What motor are you using?

Hi again John. I just read on Facebook your statement that a 3 axis brushless gimbal would need 2 BLD modules to run it. That was a bit of a surprise to me. Sounds like the BLD only handles 2 axis. Could you elaborate please? Thanks, Andrew
Just got back to the UK so have been offline a bit.
Andrew: The G-Lock has a special High-Speed Link (HSL) which multiple other devices can connect to. For these first BLD modules, they have 2 drive channels because a) I wanted the module to be compact and b) I liked the idea of the pan module being mounted out of the way up on the pan axis and the tilt/roll combined one the lower axis. It does give flexibility as a 10A, single channel version of the BLD will also be available. You can connect & configure them however you want - eg a 2-axis, 5A channel each for tilt/roll and a 10A BLD for the pan. Or you could have 3 10A BLD's on up to 6S for 3 big motors. There is no reason we can't make a 3-axis BLD module which would be less flexible - but we are already in process with this for a 3 axis, 2.5A BLD module which will connect on the same HSL bus for smaller gimbal.
jchiogna: We shot it at 720P, 60Hz on the GH2 where it is super-smooth but after exporting it as 29.97Hz for vimeo it sometimes steps like it is about 5Hz. Maybe it's just the bit-rate - but it's highly unsatisfying to watch. Also I notice how it can appear steppy when I watch it, but if I pull the slider back and watch it again it is smooth. Might be a windows or internet thing.
The production BLD modules should finally arrive in the worskshop today or tomorrow. One we program one up and make sure they are OK we will put some ordering details up. There will be a limited time opening deal initially where they will be shipped direct from us while stocks can get to dealers.
I wish I could say it is a pleasure to be back, but I'm freezing my nuts off. The weather in the UK is such a limiting factor, especially here up North.
The good news is that the production BLD modules have arrived at the workshop and are in final assembly. The signal masters are in stock too as are USB Adapters too for anyone who buys a used Radian.
Having said that, the signal master is most useful for the servo mount where it brings all the drives out away from the camera tray. For the brushless system, it only really interfaces to the receiver. If you can live with a Spektrum satellite, it can plug directly into the G-Lock. It is needed if you want to use SBUS though, in which case it also gives more flexible channel selection than with the normal G-Lock if you mix SBUS/PPM Rx with a Spektrum satellite for single/dual operators.
The launch is imminent. We are just working out the final pricing and it should be posted tomorrow along with an introductory offer. Modules will be shipped from our Thailand workshop for a limited period until the dealerships are up and running then it will be through dealers only.
Just built up my new AV200IDD gimable with two BLD's and G-Lock. I have got all latest fireware on them.
I can connect to them via the assistants but the BLD's are not giving any indication of movement and the motors are not trying to compenstae. They don't work ij thr tuning mode either. I can soutputs from the G-Lock but nowt happening. I also a a very slow flash on the BLD led not the usual faster flashing on the prototypes.. could I have the HSL links wrong somewhere?
A quick way to check if the BLD is getting HSL data is to check the LED : when it is good, the LED flash will reverse so it is normally 'on' and flashes 'off'. The sure-fire way is to connect to the G-Lock and look at the HSL status and see if they are lit up green. Also the G-Lock yellow LED will light solid when HSL data is coming in.
I'm finally wiring my brushless IDD av200 gimbal and have to figure out what the three wires on the av200 motors represent. Does it matter in what order I connect the wires from the brushless motors to the Carvec BLD?
John, it doesn't matter which you connect it. The end result will be either it turns one way or the other. You will check and set the direction using the BLD software.
One other thing : if it has the rubber roller drive, you need to bed it in so it is very smooth before you tune it. The easiest way is to get a rough tune, then use the tuning test mode to drive the gimbal automatically backwards and forwards. You can leave it running for an hour or two until it is smooth.
I am almost ready to order all the parts to build or convert a cinestar like gimbal into a brushless one with the G-Lock. From the pictures i see that the G-Lock sit on the Tilt axes next to the camera. look like a good place but what is a good place to stick the BLD modules. Will they fit into the carbon tubes for instant or do they have to have a good fix situation.
