The U8 Lite KV190 from T-MOTOR, a Chinese maker, is a large-diameter multicopter motor from the U-Efficiency series (36N42P) for propellers of 28 to 29 inches on heavy industrial copters. It is designed for 6S.
The motor weighs 243 g and measures 87.1 x 27.05 mm; its shape is wide and flat. At KV 190 and 22.2 V that works out to about 4,200 rpm at no load. The peak current of 43.7 A applies for 180 s; at 22.2 V that is about 970 W arithmetically. The maker quotes a maximum thrust of 7,300 g, 30 times the motor's own weight; measuring conditions differ between makers, so this value should be compared with others only with caution. Further KV steps, 85, 100 and 150, exist as separate versions.
For EU classification the take-off mass of the whole aircraft counts: C3 and C4 reach up to 25 kg, and above that the specific category applies; Remote ID is mandatory for C1 to C3. On 6S a battery stays below 100 Wh up to about 4.5 Ah and travels freely in hand baggage; up to about 7.2 Ah, which is 160 Wh, it needs the airline's approval, and above that it may not travel as passenger baggage.
On 6S, twice as much current flows for the same power as on 12S; connectors, leads and the ESC must carry the current with headroom. A propeller much larger than recommended overloads motor and ESC. Check the bearing run, the winding insulation under sustained heat and the bell's concentricity with its magnets.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Ask about parts availability for this build year — the running costs hang on it.
