Yep, that should do the trick. :) -- Gary

The reason some ESCs have a problem arming, a lot of the time, when used with a MR FC, is because the ESC firmware expects to see a valid signal on the servo line from the receiver right away, and if it doesn't it will fault. Most FCs, like the Naza/WK-M, take a few seconds to boot up, and start...

That's about as jello-free as I've seen with the stock props, and no isolation. :) -- Gary

Speaking of Picloc, Boris, did you ever get this to work they way you wanted on your setup? What gimbal are you using, an AV-130, or was it one of Tabb's CS gimbals? -- Gary

I agree, you just need to center the servo travel, mechanically. -- Gary

I'll try and get some endurance tests done in the next couple days as well. My setup, with two 4s-3300 packs and the GoPro, has an AUW of 6lb 8.9oz/2974g. I'm guessing 10 minutes, with a reserve, shouldn't be a problem. I'm going to do some more tests today, to try to wring out the gimbal...

I'll try and take a better pic later, but basically I used a plate and shaft adapter from a Lynxmotion.com Servo Erector Set kit that I had from some earlier gimbal work I was doing. I simply drilled three small holes in the F550 top plate with a Dremel. -- Gary

I finally got around to doing the first flight of this setup. It truly is amazing how stable the WK-M is, especially now that I have the new GPS module installed. Before, it used to take 7-8 minutes just to go from 3 to 2 red flashes, and most of the time, over 10 minutes to get down to 0...

I too had a recent Naza/F450 crash, that happened to be while I was descending, but I think that was just a coincidence. In my case, I'm pretty sure it was a bad Deans connection. Every time power is initially connected, there's a spark/zap that occurs. This ends up putting a almost...

I decided to start this thread to document the testing we are doing on this new gimbal/mount setup for the new DJI F550 hex setup. While doing the build, I was quite pleasantly surprised to see that not only was I getting very fast GPS locks, even indoors, my pesky gimbal drift problem, once the...

I had mine drop from about 30-40 feet yesterday, and the arms all survived, but I cracked the F450 top plate. Temp at the time was about 74F. I do think low temps makes the arms more brittle. If mine wasn't so heavy (4-1/2lb/2.1kg...), the plate probably would've survived. The only other...

My AUW is 2110kg/4-1/2lbs, using two 4s-2600 Hyperion G3 packs and GWS 9x5x3 3-bladed props. It's got plenty of power and the motors are barely above ambient, even after 10 minute flights. The stock 10" props, even carefully balanced, induced a lot more vibrations and made the motors run so hot...

First of all, I'm not saying these are "wonder servos" by any means. You are right, there's lots of 12-bit choices out there. There were a couple reasons why I picked them, however. First of all, although the newer Hitecs I've been using let you program the deadband space, when you put them in...

Yes, to both questions. :)

Oh I agree, there will be high-end gimbal solutions, like what DJI is doing, that gives the ultimate in "steadicam"-like performance. These will most definitely use dedicated IMUs and will make use of custom stepper-motor drives. That said, I still think there is room for improvement in a...

I'm going to have to respectfully disagree that you can't make a servo-based solution successfully take out platform motion enough that you still get smooth video. One thing I've learned recently is that most digital servos have a built-in deadband that is set around 4ms. This alone is the cause...

I agree that it might be an issue, going from warm inside temps, to freezing cold, for the IMU. I don't even venture outside, much less fly, if the temps dip down below the mid-60s, and I've never seen this white flash issue. -- Gary

This is where I get confused. If the WK-M's gimbal gains were dialed in, with a responsive mount, why would you see the larger corrections that the WK-M is making in order to do better position keeping? -- Gary

We have pool stores here that are open yearlong, but I think I also saw them at Walmart. You might be able to order them online, from their site. -- Gary

The latest version I've tested, which is v5.02, the gimbal drift problem was not​ fixed.
