Hi all
i just changed over my Source One v3 to a Source One v4 frame. Swapping over all the v3 parts to the v4 frame was not as easy as expected.
The v4 frame is slightly longer and alot thinner so Vista wiring had to be extended to accommodate. Using a 3d printed camera mounts the dji camera will not fit if slammed more than about 22mm due to the camera cutout on the top plate. This was my least favorite feature on the new design as I like a slammed design mosly for aesthetic reasons. All tpu will have to be modified and reprinted including antenna mount, motor skids and gopro camera mount.

i was very excited when tbs released the v4 frame coming in 50grams lighter than the previous generation. After a few flights I have noticed a difference in hangtime with the lighter weight frame. Overall i like the look of it, the arms interlock very well and I'm happy they kept the base plate design. I just wish I could put shorter standoff on it with the dji camera still being kept within the safety of the frame.
