Here’s some news on my first multicopter scratch build, aka “The Shuriken”. This is my first multicopter build, and I’m frankly surprised it flies, and flies well! I tried to keep it under $100 USD for the budget-minded maker, but ended up around $150 with all the extra bits.
Bill of materials:
4 x Turnigy L2210 1400kv brushless outrunner ($9.14pc *4 = $36.65)
4 x Hobbyking 25-30A esc ($6.99pc * 4 = $27.96)
Multiwii 328P Flight Controller ($27.29)
Zippy Flightmax 3S 2200mah Lipo ($13.13)
HK Quadcopter power distribution board ($4.09)
4 x 8×4.5 counter rotating propellers ($2.69 x 2 = $5.38) Buy two sets just in case.
3mm MDF board for frame parts (~$10)
Pine rectangular wooden dowel, length 1200mm, width 20mm, height 12mm (~$6)
Zip Ties $5
Foam cones from Kmart $6
Critique on parts:
Battery: go bigger, like 4000mah 30C
Frame: use thin fiberglass or something lighter than MDF.
Frame: buy the premade one from HK. Cheaper and probably better than you can do at home!
The completed quad on the maiden flight. Windy, but handled well.
