I also added some silicone fuel tubing to the stand-offs to size them correctly for the new dampers which have an 8mm hole. This mount is made from a piece of 1.5mm CF plate (HobbyKing) with the new two piece dampers screwed on. It's a little heavier than the aluminum tube but it does a much better job of damping the high frequency vibration. I was given a link to some inexpensive rubber dampers from nakelp86 on RC Groups and they were the inspiration for a new mount idea.

The dimensions shown are designed to accommodate a GoPro2 or GoPr3 camera:Ĭlick on either image to see or save a PDF copy Here are two simple drawings of the Pitch and Roll frames. Weights: Gimbal hardware including motors - 6oz (171gr) Control boards and wire - 0.85oz (24gr) Total gimbal weight - 6.85oz (195gr) Parts List: 1ea Mount - Sqaure aluminum tubing, 1"sq (25mm) x 2"L (50mm) x 1/16"wall (1.5mm) 1ea Pitch bracket - Aluminum flatbar, 1" x 1/8" (3mm) x 4-1/2" (112mm) 1ea Roll bracket - Aluminum flatbar, 1" x 1/8" (3mm) x 4-1/4" (106mm) 12ea Socket Cap screw - 3mm x 6mm SS 8ea Socket Cap screw - 1.5mm x 6mm SS 2ea Nylon spacers - 9mm x 5mm x 2mm 2ea Aluminum Standoffs - 5mm x 31.7mm 4ea Rubber Grometts - 5/15" x 3/16" x 1/16" 2ea RCTimer 2212/80 Brushless Gimbal motors 1ea RCTimer Martinez V1.0 control board This will remove the need to make the mount holes slotted or the addition of balance weights.Īssembled for balancing - Hardware and wires not shownīecause I already had a set of extra motors and an extra Martinez brushless controller board, I thought it would be great to add this to my new Hoverthings Parts Bin Quad project. The length of the bracket and subsequent position of the Roll motor mount hole is determined by assembling the camera, camera straps, pitch bracket, pitch motor, IMU and wires and then finding the balance point on the roll bracket. Cut bend and rill all but the roll motor mount holes, save them for last. The Roll bracket is built using the same material and is 1-1/2" (38mm) deep. In every case though, you need to check and adjust this distance so that no matter what position the camera is in it stays in that position balanced. The depth of the camera bracket for this camera is 1" (25mm) from the pitch motor center to the base. The Pitch (camera) bracket needs to be long enough to accommodate my GoPro2 with the video out plug installed so it ended up at 3" (76mm). Like the tube mount I drilled out significant holes for lightening (every gram counts!). 080TH.īoth swing brackets are made from aluminum flat bar 1"W x 1/8"TH. The nylon spacers are 3/16"ID x 3/8"OB x. The grommets are standard black rubber and they fit a 5/16" hole. The main mount tube is made simply from a piece of square aluminum tube sized: 1" square x 1/16" wall thickness. I did have to cut them down to 1-1/4" in length to fit the Hoverthings frame.
These are aluminum and are tapped for 3mm screws on each end. The stand-offs are leftover from the TBS Disco kit but similar ones can be purchased from online stores like McMaster Carr.
It utilizes very minimal vibration damping so it is imperative you remove all vibration you can by carefully balancing the props and motors.Īll the pieces were made or purchased from a local hardware store with the exception of the stand-offs. It has worked very well on that machine so I decided to use it again on a new Hoverthings build I am doing. The mount you see here I originally developed for my TBS Disco. The weights shown include the control board, IMU board and wires without the camera. The Gimbal build shown here is a little heavier at ~6.9oz (196gr) because of the larger RCTimer motors but this is still well under what you can buy today. The weight add, with the small iPower motors is 6.2oz (176gr). So far, Success! The set up I have on my TBS Disco adds almost zero additional frontal area and well under 2 square inches side area. So, I decided on a front mount to limit the wind profile and to use the lightest and smallest components I could easily make to limit the weight. And this was to carry a GoPro! The other issue I found was they are all designed to hang from the bottom and what this does is create an enormous wind profile which can be a handful to fly in. The issue I had with the purchased units was their size and weight, some even weighing close to 16oz (450gr). CAD Concept (Mouse over for exploded view)Īfter buying and trying a few of the offerings in the camera gimbal world I decided to make my own.
