Now that is very weird. Did you let it run until the LED started flashing only twice? On mine, it is fine until it finds the 5th sat, regardless of what mode it is in, and then it starts the drifting/wandering. Very repeatable. You don't even need to use a mount. You can simply plug in a servo...

A lot of people have had success using a FyeTech FY-30A 3-axis stabilizer to control the gimbal servos. I would think you could also use a pair of heading hold tail gyros, but I've never tried this. That said, I don't think there's anything wrong with the WK-M's gimbal outputs, except for the...

Wow, glad I waited. Thanks for the info. Hopefully they will issue a new version, that fixes what they broke, and also takes care of the camera mount twitching/hunting/drifting problem. I know they are working on the latter. I received a number of PMs from Sidney, trying to nail down the...

Yes, I can see how that could make a difference, having the external pots. I haven't played with these mounts enough yet to really do much more than theorize, I'm afraid. :) That will change soon, however, because I hope to have my own CS 6 flying by the weekend. -- Gary

Actually, I never meant to imply that I thought the gains adjusted the speed of the outputs. I agree, that what it really controls is how much angular movement the servo will be commanded to move, in response to a given angle that the platform moves. I basically have done the same sort of...

Thanks. :) One thing I've noticed, in all my playing around with the gimbals, and several different mounts, is that the gains are basically a way to "tune" the outputs to the amount of reduction in each axis. With the gains at 20, it seems well matched to a direct-drive/1:1 setup. With a mount...

Was the system initialized to where the red LED only flashes twice, once or not at all? For some odd reason, the twitches only start happening once the system sees enough sats that it is not flashing three times anymore. Sidney says the engineers are working on it, but he's now off for the...

They are working on it. :) -- Gary

I'm finally making progress on my CineStar 6 build. I can't go too far without the motors, but they were shipped today. Basically, they are the same as the QC 3328, with a kV around 700, I think. I also have six HobbyWing 40A Platinum ESCs on there way, so I'm hoping to get them by Wednesday as...

Hi David -- I just updated my ServoBlocks thread with the parts info. -- Gary

For those looking for a parts list for this setup, Here it is: The main pieces are built around two of these: ServoCity Hitec ServoBlocks. I added two of these 0.770" 5/8" bore tube clamps and a 2" length of 5/8" tubing. The key to getting the best performance is to use fast, high resolution...

I don't have any lag, as my setup is using Hitec HS-7940TH digitals, and they are running on 7.4V, via a programmable CC 10A BEC. These also have the 12-bit, hires feature, so the action, even in my direct drive setup, is actually quite smooth (see this post...). The only issue I'm having right...

Okay, so Sydney sent me a PM, over on RCGroups, that they will have someone look at the "drift"/hunting problem, that occurs around the neutral point, on Monday (tomorrow...). I did another flight test yesterday, and it is clear that the only jello I'm getting at all is right around the neutral...

BTW, what Sydney is going to have them look at is the small drifting that occurs right at the neutral point. This is a bit different than a steady "twitching", that can happen with low resolution servos in mounts with lots of backlash/play. This drifting is like it is walking in the same...

Yes, it was me. Sydney PM'd me to say they will have someone look at this first thing Monday, their time. Yes, I'd definitely try setting the gain to 20, for both settings. What I do is hold the platform up so that I can line up the top of the GoPro with something horizontal. As you move the...

Have you tried just connecting the trigger/servo directly to the regular CH8 output on your receiver? I think the regular and S.Bus outputs are both on all the time. -- Gary

It looks like this is more or less a direct-drive, type of mount, like my custom ServoBlocks-based version, so you'll see quite a bit of of improvement with some faster, 12-bit minis, like the Savox SH-1357s, or the Hitec HS-7235MHs. The higher resolution especially. For the gains, I think you...

I think the reason you don't seem to see the twitch is because of the large reduction the AV-130 has, in both pitch and roll, and because they are belt drives. I also tried it on my reworked mkTR mount, and it is much less noticeable, but it is still there. This has a lot less reduction in the...

Instead of higher kV, why not higher voltage, like 5s? I'm pretty well convinced now that I'm going to use basically the same size/kV motors, with my 11x5 Graupners, and run them on 5s. Also, instead of ballast, you could use more/larger batteries. :) I'm thinking of a couple of 5s-8000s will do...

Wow, that is smooth. Any hit of wobbling in the wind? -- Gary
