Editor's notes
peak_torque 433 Nm is the 100:1 figure to match gear_ratio; the 160:1 variant is 484 Nm. Unverified (free text): per-variant-specs; manufacturer-direct-price. The official en.zeroerr.cn page fetched was generic (no per-model numbers). rcdrone spec table lists 6.49 kg while its drawing says 6.7 kg. Peak 484 Nm is the 160:1 start/stop figure; 100:1 is 433 Nm. Variant names come from product URLs only.
