Micro quadrocopter frame - semiducted - Beecheese frame V4 by Noctaro

Last crawled date: 3 years ago

Enjoy my new 3d design for a brushless micro quadrocopter. Based on the brushed quadrocopter idea of stlyesuxx. It uses 2.5 inch propeller and 2S lipo in combination with brushless dys 7000kv 1104 motors. The AUW of the micro quadcopter is around 140grams using a 850mah battery pack.
Thrust should be around 150 grams per motor with 2S and 2540 tribalde props.
So it has quite some punch :)
If you crash, it might break, but it still does an good job at protecting your components. Most times, you will be able to fix the frame using superglue or a print pen. Moving the components to a new print is done within minutes.
My flightcontrolboard is flashed with betaflight 3.2.4 at standart PID settings and with dynamic filter enabled. Only rates are adjusted.
If you want to add a small action cam, you might need to retune your pid and fly acro a bit less hard. But it willy carry a mobius or runcam 2, so you get some nice 1080p footage from it.
The runcam split mini seems to be a perfect fit for this frame. It just needs good dampening.
Of course i will get you updated as soon as i find a good solution. For now i get some tearing in the footage.
If you have some flexible filament you may print the tpu motor mounts to reduce vibrations on your frame. For me this worked quite good.
You may also try to print the short standoffs using tpu. In addition i mounted my fc board onto slices of "oropax" earplugs. This works quite well.
You may mount all the usual FC sizes to this frame. 30.5mm, 20mm, 16mm
This setup is able to carry a runcam split 1/2 or runcam split mini.
It will fit M3 screws for the frame standoffs and the 30mm flightboards. (10x)
Use M2 screws for the flight boards with a diameter of 20mm or 16mm (4 - 12x)
I have also added a tiny bit screwdriver, in case you have troubles reaching the cam mount, you might find it usefull.
I would be very happy to see your make and get some feedback :)
Update 1:
Fixed the meduim standoff floating.
Added standoffs with mounting holes for Runcam Split Mini.
Update 2:
Added better standoffs for Runcam Split Mini
Added alternate frame design
Update 3:

Added another frame design - much better stability but a bit more weight
