Sourcing the components and obtaining specifications
I need to build a careful specifications chart for this one, as flight has some rather tight requirements. Weight is of primary consideration and overrides all others to a large extent.
Echo Dot 2nd Gen
Width: 84mm
Depth: 84mm
Height: 32mm
Weight: 163 grams
Naze Hardware
Width: 36mm
Depth: 36mm
Height: ?
Weight: 7.3 grams
Raspberry Pi Zero
Width: 65mm
Depth: 31mm
Height: 12mm
Weight: 8.5 grams
Raspberry Pi Camera
Width: 25mm
Depth: 25mm
Height: 9mm
Weight: Estimated 3 grams
Turbines
Width: ?
Depth: ?
Height: ?
Weight: ?
Motors 1806 2300kv 2-3S / 2-4S
Width: 23mm
Depth: 23mm
Height: 26.4mm
Weight: 18 x 4 = 82 grams
Thrust: 460 grams
ESCs BLHeli 20A
Width: 42mm
Depth: 20mm
Height: 8mm
Weight: 11 x 4 = 44 grams
Batteries Floureon 3S 2200mAh 11.1v
Width: 106
Depth: 25
Height: 33
Weight: 175 x 2 = 350 grams
Voltage: 11.1v
Discharge: 25C
Shell Depron / Polycarbonate
Width: ?
Depth: ?
Height: ?
Weight: Estimated 20 - 30 grams
Total Weight: 687.8 grams
Total Thrust: 1840 grams
Thrust-To-Weight Ratio: 2.675 (Assuming Single Standard Prop)
Hover Throttle: 36% (Assuming Single Standard Prop)
According to Ken.do
Weight of frame, dot, pi, cam assumed to be 250g or less.
All-up-weight of about 630g (includes everything)
Motors - DYS 1806-2300kv
Battery - 3s 2200mah
Escs - 20A
Frame - 250mm
With this setup, flight time is about 10 min. This is fine depending on usage desired. Performance will be acro worthy.
I think that about covers it. All I have to do now then, is increase the efficiency of the turbines and try to make them quieter. A slower-running motor and more lifting surface, and the ducting will help with this.
