I have always appreciated the rigidity and good flying characteristics of the TBS Source V frame.  Unfortunately, it is really limiting when you want to put a DJI Vista and gps on it, real sma antenna + trying to shoehorn a GoPro on it.  

After looking at the design, I made 4 new parts that replace the top and bottom sections of the frame + 2 new braces and 2mm standoffs to provide a forward mounting location for the camera that isn't completely obscured by the props like the stock design.   The added benefit is I will be able to design a 4 screw-mounted tpu base for a full-sized camera.   


 It was interesting cutting out the interlocking sections for the vertical legs- I had to use a 1mm PCD(poly crystaline diamond) coated cutter to make the tiny cutouts.  Here are a few pics:

Any suggestions would be appreciated...

I don’t have any suggestions, but it does look awesome.

Update,  finished the build and successfully did my first flight.  This was my first attempt at building something that is focused on max speed above all else.  
Major components were:

Iflight f7 Blitz mini stack 55 amp

KO DEMON SEED CRYO 2208 2540KV motors. FYI, measured 1850 kg per motor on a thrust bench test in this short test video:




Master screw 5x4.5 biprops(training wheels because I haven't flown this fast before)

vista and nebula pro

crossfire nano

matek M8Q-5883

iflight long range antenna

Tattu R-Line 1550 mah 6s

Overall, I am really happy with the mod.  It is ridiculously stiff and now has enough real estate to properly mount stuff while being lightish at 80 grams for the full frame.

The first flight was very humbling...  the craft is so over- powered that at first I thought it might do a fly away because any throttle stick and it just jumps.  i dropped the throttle and it drops like it should so after a few laps around the house I found it was surprisingly flyable.  I will definitely need to find some open space to test this guy out and learn how to fly at a 50 degree angle or so.  Kudos to John at addictive RC for sharing his settings for blheli to keep things from overheating or de-syncing and advice on the motors.

I have a custom tpu gopro mount printing so I hope to share some video at some point if I can fly it at full speed without crashing.  Considering the power to ratio of this thing with 4x 1850kg worth of thrust, it should be a rocket...
