GHH PT Pan/Tilt Camera Platform Anti-Vibration Camera Mount RC FPV 9g 12g servo

If you can't figure out how to trim a servo horn to fit, you probably shouldn't be in the hobby. Is this the best gimbal out there? No. No bearings, relies on the servo mechanism. Just ordered a second one for another airframe. 1 - There are no instructions, but 5 minutes of dry fitting and you will figure it out pretty quick. 2 - standard 9G servos fit without a problem. BUT YOU WILL NEED TO TRIM SERVO HORNS TO FIT. (oh my, so difficult) Some quick and dirty instructions. 1 - start the LONG SCREWS (machine threaded) through the two middle plates. These are the ones with the trianglular holes cut out. 2 - trim, glue and screw a modified small single ended horn into the side of the middle bracket. 3 - install the servo in the servo horn mentioned in #2 4 - a small drop of hot glue on the front of the servo will hold the camera plat on just fine- line up the axle hole, and glue it in place. (Hot glue comes right off with a little drop of rubbing alcohol FYI) 5 - trim a small servo horn to fit in the round piece and glue it in place 6 - push servo#2 through the rectangular opening in the middle plate FROM THE BOTTOM and tighten the 2 side screws. 7 - push rotate servo down into the round bottom plate and screw in the servo horn screw. You're done. I'll video the next one I build.

I thought this was a great alternative to an assembled kit as I have many micro servos already and frequently build and assemble devices. I knew it would arrive without much padding and without instructions from other reviewers. There are good instructions online from Adafruit, so that was not big deal. Unfortunately, I could not get any of the servos to fit properly. Perhaps I got a different version than others, but the servo doesn't quite fill the hole and were a bit loose. Though it is clear the ends of the horn have to be trimmed to fit, this was not enough. The molding doesn't allow the horns to sit flat unless a lot of shaved from the sides of the horns as well. This is not easy to do! Even after this, the holes do not line up with servo horns. Two holes are too far out to be of any use at all, so there isn't much to hold this together, especially considering a severely weakened horn. I tried three very different 9g servo brands and their horns (including Tower Pros as recommended by Adafruit), but none fit and all had these issues. There are probably different versions of this kit and I happened to get a bad one.

It's a little big but what are you going to do. If you make it a smaller it be better.

Absolute garbage! Cheap plastic the you have to trim ur horns down to nearly nothing. Head mount wobbles bad. Had to use directions from ardufruit website. Would send it back except it not worth the gas to drop it off at the shipper. Yeah this thing is CHEAP!

I have two sets of servo horns, with different spline counts. One fits perfectly, but was the wrong spline for the servos I had on hand. So I used the other servo horns, and trimmed them with a hobby knife to make them fit.

First I had to return one of these because of the cheap plastic used in construction. If you feel you must buy this, under no circumstances can you over-torque the screws, instead use loctite and don't over-tighten. Then once I got it together, and it took some modification of servo horns to do so, it lasted about a week. The mount tabs and screw holes for the upper TILT servo are 1) improperly sized and 2) not engineered to withstand the load of the camera being torqued at the 9 gram servo force that is applied. Both attachment tabs snapped in about a week of use. In fact, I had an ESP32CAM on a breadboard attached which is pretty light weight. Secondly, the way the lower PAN servo mounts to the base makes for an unstable turning/pivot point as the entire load above it (mount, two servos [including PAN servo itself], camera, and hardware) must balance on the spline of the upside-down lower servo. The end result is a wobbly jerky rotation even using servo easing software!

Zero instructions.. that's fine its not rocket science. As others have said you do have to custom trim the servo horns but that part is still not a huge deal I guess.. then you will come to find the bottom servo hole is too small for a 9g servo so you have to shave the hole out. Be careful not to shave too much or you'll have play. I couldn't get a 12g in the top but I did manage a 9g with 6 washers per side to move it closer to the servo gear side. All and all it does work after mods but even at this price we shouldn't have to fix so many issues. Pros is does have good range of movement and if you use metal gear servo for bottom its decently sturdy

Works great. A little assembling and using my servos. Was able to do the job I wanted done. I would recommend this to someone into this type of project.
