NOW IT WORKS!!! PRINTABLE AND WORKING DESIGN! Minor changes will come though :) New design of the TBS Discovery Gimbal made by Nathan_. Thank you for the solide inspiration! I recently added a main plate, which offers the possibility to add a FPV video transmitter mount specially designed for the FatShark 250mW 5.8 gHz TX. It offers a simply solution without having to hook up the TX under an arm or on the top plate. The transmitter is then far enough from the RC receiver and the GPS antenna can be mounted in the middle of the top plate, without fearing any interference. If you want this then download and print the different main plate and the TX mount. I added my own GoPro mount to the design. It offers the possibility to mount the GoPro upside down if you want and has two openings to access the buttons. Further this mount is capable of useing wiht the original 30-pin FPV out both upside down and normal. Note that it is still possible to use the normal USB FPV out if you like... I didn't like that the vibration dampers aren't mounted vertically but sideways in the Nathan_ design. Therefore I changed it and now the GoPro can be mounted even closer to the frame, which reduces the possibility of oscillation to appear. pictures show an older version than available! My new design which includes the back vibration damper inside the TBS frame, not on the right side like now is now finished and uploaded as a new thing. RELEASE NOTES: -V_0.2.3: improvement of the dimensions, shaft hole added in roll_mount, new main_plate, less material used -V_0.2.2: minor improvements, bottom plate thickness increased, rounded edges for the roll_mount -V_0.2.1: better stability, new mounting holes -V_0.2: improved pitch mount; new main plate and corresponding roll mount coming soon -V_0.1.1 fixed the dimension problem of the STL files -V_0.1: still faulty. Not printable yet because the roll mount is to low and to long. Material needed: 1x Main plate 1x Roll mount 1x Pitch mount 1x GoPro mount (e.g. the one from Nathan_) 4x Vibration damper 2x 2208 Gimbal BL Motors 1x BGC (simpleBGC from BaseCam or any other) and the TBS Discovery :)
