Manufacturer bench figures (VCI Hobby bench, 22000 and 29000 KV at 1S (4 V) on three props each, stepped by current rather than throttle); real-world thrust varies with ESC, battery sag and prop condition.

Spark 0702 vs other 0702 motors on 1S

The same thrust costs different power on different motors. Each line is one maker's own bench series (1S, its own prop), drawn as grams of thrust per watt against thrust, so a higher line makes that thrust for less battery current. Throttle percent is left out on purpose: it means something different on every maker's rig.

Power at 10 g and 20 g is read off each maker's curve, straight-line between its two nearest bench points; 20 g is the highest thrust every motor here reached. Different props and rigs move these curves as much as the motor does, so compare rows on a similar prop. Peak thrust of every 0702 motor: 0702 motors compared.

Thrust-to-weight with this motor

Four VCI HOBBY Spark 0702 motors at 26 g max thrust each give 104 g: 2:1, the minimum to fly, up to 52 g all-up; 4:1 (freestyle) up to 26 g; 8:1 (racing) up to 13 g.

Where this data comes from

The rows are VCI Hobby's own 'Testing Dates' tables, one per winding, published as images on the motor's RaceDayQuads listing rather than on vcihobby.com: VCI's own catalogue has no id for this motor at all - the 0702 line there is now the PRO LITE and the PRO DB - so the retailer's copy of the maker's sheet is the only surviving publication of it. THESE SHEETS STEP THE CURRENT, NOT THE THROTTLE: the columns are Model / Propeller / Voltage / Current / Thrust / Efficiency / Power / Temperature, the rows walk 0.50 A upwards to each winding's peak, and there is no throttle and no RPM column at all, so both are empty on every row here. Every one of the 41 rows reproduces both of the sheets' own identities: the printed Power is 4 V x the printed current, and the printed Efficiency is Thrust / that Power. The cross-check against each Specifications panel lands on a row: the 22000 KV panel's 3.3 A / 13.2 W and the 29000 KV panel's 4 A / 16 W are each that winding's GF 35mm-3 last row. Identity with our two retail listings is nine figures to the digit - 9S12P, Ø7*L2 mm stator, Ø9*L12.2 mm body, Ø1 mm shaft, 1S (4 V), 30AWG 30 mm leads, 350 and 275 mOhm and 1.53 / 1.52 g including cable, and weight_g is the first-listed winding's figure, 1.53 g at 22000 KV (1.52 g at 29000 KV), named beside it (re-read 2026-10-20 off both Specifications panels, 'Weight(Incl. Cable)'; until then the page showed the 29000 KV figure). MAX THRUST READS 26.00 g, the 22000 KV winding's GF 35mm-3 peak, against 24.80 g for the 29000 KV. Temperature is one figure per prop run and not per row (53-68 C over the six runs), so it is not carried. The listing's third image is VCI's dimension drawing, which calls out 3-M1.4 EQS on a Ø6.6 bolt circle: a three-hole mount, so mount_mm stays empty.
