Manufacturer bench figures (VCI Hobby bench, 1850 KV at 6S (24 V) on three 5in props, 2150 KV at 6S (24 V) and 3450 KV at 4S (16 V) on one each, 8 throttle points (30-100%) per run); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

The rows are VCI Hobby's own 'Testing Data' table, published as an image in the Specifications tab of the motor's product page on vcihobby.com. VCI sells and benches this motor in three windings and all three tables are here; `kv_options` keeps the 2150 KV our retail source sells, so MAX THRUST READS 1340 g, WHICH IS THE 1850 KV WINDING on a GF 5125-3 - the 2150 KV's own best is 1028 g. The three windings were benched on different packs - 1850 and 2150 KV at 6S (24 V), 3450 KV at 4S (16 V) - and each row reproduces its own sheet's identities against its own voltage. Each panel lands on a row: 24.86 A / 596.64 W is the 1850 KV's GF 5125-3 100% row, 21.51 A / 516.24 W the 2150 KV's and 34.89 A / 558.24 W the 3450 KV's. TWO SOURCE FACTS RECORDED RATHER THAN REPAIRED: the 1850 KV's GF 5125-3 run prints an RPM column that wanders instead of climbing (22553 at 70% against 24515 at 60%, then 21622 at 100% against 32652 at 90%), and the 3450 KV's 100% row prints 81794 RPM - roughly double its 90% figure and above the 55200 RPM that 3450 KV x 16 V allows unloaded. Both are published as printed. The panels give a per-winding internal resistance, 104, 90 and 45 mOhm, which is why resistance_mohm stays empty: this page is one motor in three windings and the field holds one number. Identity with our retail listing is 2150 KV, the 2006 stator (the panels print Ø20*L6 mm), 6S and 21.4 g including cable; the panels' shaft is written Ø1.5 mm. The 1850 KV panel prints a shorter body, Ø24.6*L18.7 mm, against the Ø24.6*L19.7 mm the other two state and this page carries.
