For motor selection, setup, and compatibility questions (KV choice, prop range, and 3–6S matching), contact support@rcdrone.top or visit https://rcdrone.top/.
Fitment details are easy to confirm with the PRO-2814 mechanical drawing, including motor diameter, overall length, shaft thread, and mounting pattern.
Performance data for the 730KV version compares thrust, current draw, RPM, and efficiency across several 3-blade prop options at 25.2V.
