Representative price arithmetic (careful, digit-by-digit)

I used the representative prices above and added them into two totals:

Base racing/freestyle quad (no action camera, with gimbal optional excluded):

Frame $21.99

Motors (4×) $44.00

ESC (4-in-1) $23.90

Flight controller $76.99

Props $5.39

Battery $25.98

Charger $47.00

Transmitter $150.00

Receiver $25.00

FPV camera $29.99

VTX $32.99

Antennas $8.00

PDB / wiring $8.00

Battery strap $2.00

Screws & hardware $5.00

Landing gear $8.00

GPS $35.00

Gimbal (optional, included below as chosen) $120.00

Now add (stepwise, carefully):

21.99 + 44.00 = 65.99

65.99 + 23.90 = 89.89

89.89 + 76.99 = 166.88

166.88 + 5.39 = 172.27

172.27 + 25.98 = 198.25

198.25 + 47.00 = 245.25

245.25 + 150.00 = 395.25

395.25 + 25.00 = 420.25

420.25 + 29.99 = 450.24

450.24 + 32.99 = 483.23

483.23 + 8.00 = 491.23

491.23 + 8.00 = 499.23

499.23 + 2.00 = 501.23

501.23 + 5.00 = 506.23

506.23 + 8.00 = 514.23

514.23 + 35.00 = 549.23

549.23 + 120.00 = $669.23

Estimated total (base build including a small gimbal but excluding an action camera): $669.23 USD.

If you also add an action camera like a mid-range GoPro (~$399), total becomes:
669.23 + 399.00 = $1,068.23 USD.

(If you forgo the gimbal, subtract $120 to get ~$549.23 for the base quad w/out camera.)

I have create this for my Real Estate Panorama Photo Editing Services.
