As V1 was with crappy Radiolink reciever, new one is with TBS diversity, GPS, camera more in front and lot of 3D parts.
This is just update of V1 GMork: https://rotorbuilds.com/build/27717

In first version there was no place for GPS (as Mito F2 is mostly freestile frame, also there was prop in camera view. so I did GPS "sting" and offset camera forward. Also holes for silicon tubes for holding gopro session to have some dumping for Gyroflow.

Despite is 6" frame I put 7" ones on it and with no prop in view.
As usual started with sketchup and caliper, this was a plan to build (front props mower stile)
I really like how close are those 7" props on 6" frame

all 3D parts was SLA printed from flexible resin (F39)

concept of camera most in front and GPS out of electrical noise tilted 30°

this was just test version (half of the part) XT60, capacitor and LEDs inside a 3D print

camera in front, so more place to fit finder

electronic was mostly same as on V1, just a bit nicer cable management, all cables twisted.

one UART for reciever and one for INAV telemetry

original heatsink removed from VTX and add heatpad toucing top carbon plate.

and first idea was to place antenas on arms (but after cuting them with props found out that is not good idea

so place them on gopro do the job:

This is awesome! I love to see major customizations like this. I've never seen a camera mount with silicone tubes for damping. Does it work well?
I'm curious about the flexible resin as well. Do you know how F39 compares to Siraya Tech Tenacious? I've had to add normal resin to this to make it less rubbery, and haven't found a perfect blend to make it similar to FDM TPU print flexibility.

That resin looks ideal! I might have to try it out. I didn't start using reelsteady until i already had a hero8, so I've never really needed much damping but now that I am flying larger mirrorless cams I have been thinking about designing a mount for them. I'm using the shendrones mounts for now, and I have some alphagel dampers on the way, but your use of tubing has my wheels turning. Thanks for the info! :)

Feel free to join our Gyroflow discord server, theres so much information about stabilization in general, dumping, and using mirrorless stuff:) https://discord.gg/ZrECaGRP

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
