If you go past these holes you risk cutting into some traces and possibly shorting or permanently damaging part of the PDB. I cut up to the bolt holes for the front two frame standoffs. Don’t be too wary of cutting off the FPV camera mounting plate once the gimbal is installed the original FPV camera mounting location won’t have a good view anyway. If you want to move the gimbal back more, whether for center of gravity issues or just aesthetics, the front of the frame will have to be chopped off. Top view of installed rail system with gimbal and controller attached. What you will notice is that the gimbal will have to be mounted far forward in order to clear the bottom plate of the Discovery, where the original camera mounting point is. If not then you may need to get creative using zip ties or scrap pieces of carbon/wood to get a solid mounting surface. If you are using a gimbal like my 3D printed design, then you can simply slide the gimbal onto the carbon tubes and be done. Depending on the size of your gimbal you may want more or less extension to the leg height.ĭJI flamewheel legs with extensions attached. Files for this print are available here if you’d like to make them. With a 3D printer available, I made some 3D printed legs extensions that blend in nicely with the stock legs. You can simply glue some Popsicle sticks to the legs, or you could drill holes to fit carbon rods. If you install the gimbal at this point it will probably be touching the ground because the standard flamewheel arms are not tall enough. Note bolts do not interfere with the traces on the top plate.Īt this point you can install the carbon tube rail system on top of the TBS Discovery. You can easily make some out of thin wood or an old gift card. The bolts that hold the tube holders on are a little long for the Discovery so I 3D printed some spacers. If your gimbal does not have a way to mount to rails then space the carbon tubes to your liking so you can improvise a mounting method. If you are using my 3D printed gimbal design, the center to center distance of the carbon tubes should be 68mm, but make sure to check in case yours varies. The mounts will have to be spaced to fit the mounting points of your gimbal if your gimbal has them. You have to be careful though because there are traces in the top plate for receiver connections you probably don’t want to destroy or short out by drilling through. To mount the tube holders you need to drill holes through the top plate of the TBS Discovery. Of course you can use any size tube mount and tube depending on what is available and the size of your gimbal. GetFPV has these 10mm carbon tubes that will serve as the rails. You can buy the tube mounts individually, but they will probably cost more. Hobbyking sells these 10mm carbon tube holders as part of a battery mounting system. Starting with the rail system I sourced the following parts. An additional problem is the Discovery is not very tall, so leg extensions have to be added to give the gimbal clearance. To mount a three axis gimbal the solution is to add rails to the top plate of the discovery, from which the gimbal can hang from. TBS Discovery Pro Credit: Team Blacksheep Original TBS Discovery Credit: Team Blacksheep At the moment there is no three axis gimbal version of the TBS Discovery, which is why this mod exists. Team Blacksheep later released the TBS Discovery Pro which incorporates a two axis gimbal. It utilizes a small ledge on the front of the frame to hard mount a GoPro and a FPV camera. The original TBS Discovery was never designed for a gimbal. Unfortunately I do not know the name of the person behind it, but all credit for this mod should go to them. I came across a great project and website documenting a TBS Discovery 3-axis gimbal mod. Back in the fall of 2015 I was debating airframes to carry a three axis gimbal.
