Brushless beecheese frame (Semi ducted micro brushless frame)

cults3d

My First Design for a Brushless Micro Quadcopter. So far, it works quite well. This design is not superlight, but it can take some hits. Just remember, it's no tank. I've found that using holes in your ducts (propguards) reduces weight and wind resistance while keeping your props and motors safe. I crashed a few frames, but my components never took any damage. I flew it with an 850mah 3S Lipo, which might be a bit heavy for this setup. I would recommend around 600mah with at least 45C at 3S. The 2S felt a bit like a brushed copter. As you can see in the motors display of the posted video, they max out very often, even during quite chilled flight style. I wouldn't recommend it for acro. But for a bit of cruising around, it's still fun, even at only 2S. And motors come down quite cold. You could use other props for this combo to be a rocket on 2S either. It flies with an old NAZE32 for now. Will be replaced with an F4 board with OSD soon. The DYS 1104 7000KV motors work great as soon as you find the right settings for your filters. Otherwise, they will burn your frame or themselves. The filters are quite a bit off from standard settings. Yaw axis was worst. I had to reduce gyro lpf on yaw to 60hz to get a clean gyro line. This may have to do with vibrations coming from the frame itself. The motor has most vibration around 150Hz, so I set notch 1 to 120-160hz. Dynamic filtering might do a great job, but I can't test it on this old F1 board. When powering your quad from 3S, you can feel the power! Just check the motor temperatures. It should fit a Runcam Split. I just don't have one to test it. If you have some flexible filament, you may print the TPU motor mounts to reduce vibrations on your frame. For me, this worked quite well. You may also try printing the short standoffs using TPU. I didn't test it, but this should also reduce vibrations. For now, I mounted my board onto slices of "Oropax" earplugs. This works quite well. The camclip could also work well with some kinds of TPU. I would be very happy to see your make and get some feedback! Update 01: I have added more rigid and better-fitting standoffs. Update 02: Added an adapter plate for 16x16mm and 20x20mm ESC/FC boards.

I use the Flysky I6 with SBUS mod. https://goo.gl/GwRqK4 (Link to Banggood) FPV goggles of your choice. I use the Kylin Vision with Eachine DVR mod.

Afterwards, you may use ABS or anything like that.
