3 inch FPV frame sub 250g

• 13xx to 15xx motors (with 12x12 or 14x14mm mounting holes)
• 20x20 or 25,5x25,5mm stack
• 19mm camera
• 20x20 VTX (Caddx Vista ready) and optional mounts.

Use supports except for the rear roof, as you can see in the picture. The lipo holder is almost the same than for the Qarks 150 and designed for 4S 650Mah with 30x20 dimensions, I’ll add some holes to mount it. I’ve achieved the first build with the following and it really fly like a charm (maiden video soon) :

• Emax RS1306B 4000kv or TBS Podracer 1505 3600KV motors
• JHEMCU GHF411AIO Pro Flight controller (AIO F4 with 25A esc)
• Rush Tank Mini 5.8Ghz Vtx
• Micro Lollipop antenna
• Caddx Ratel 1200tvl camera

For the first try, I’ve set 1.6mm wall thickness 1.2mm top/bottom 50% infill EDIT 18/10/2021 Added Runcam 2 holder and updated frame. On the v2 i've raised up the base plate from 2.5 to 3mm, rounded some corners and modified the camera mount. EDIT 20/10/2021 Added Runcam 2 holder with 18° (the previous has only 8°, suitable for low ridiing). You'll find also some pictures of my V2 build with the CADDX Vista, it still under 250g,.even if I spent 5g by using 100% infill. Now the next challenge is to design a little Immortal T antenna mount that clip on the backside. EDIT 24/10/2021 Added a RX mount plate that fit under the top mount, but also a fin top and the famous Immortal T mount (with a warning about a thin wall detected, but it's not a real problem). Very last thing will be the motors protections. EDIT 26/10/2021 After some crashes on concrete or on bushes, I've realized that the side uprights are too thin, even with rounded junctions, they can break too fast for me, so i've decided to remove them, the main structure still very stiff. The V3 will save some weight and a bit of wind resistance, because as you can see i'ts more esthetic than really a reinforcement... EDIT 30/10/2021 Universal lipo holder and motor guards. EDIT 17/05/2022 Prop guards for safety in case of proximity chasing etc and V4 of the frame with rounded parts to reinforce the upper structure (as requested :) ) EDIT 25/06/2022 SMO 4K soft mount @++
