Will the 8015 VTOL 150 KV lift your aircraft?

Enter your all-up weight, motor count, propeller and battery. Every result is read off the measured curves, not a datasheet.

05/ Questions

What do engineers ask about the 8015 VTOL 150 KV?

What is the maximum thrust of the 8015 VTOL 150 KV?

15.0 kg static per motor on 12S with a 28 × 9.2 in carbon-fibre propeller at 100 % throttle, drawing 85.9 A and 3910 W. Bench run of 25 March 2026.

What is its continuous rating?

1447.8 W and 29.9 A for 180 s, at 70 % throttle on a 26 × 8.5 in CF propeller at 12S: 7.42 kg at 5.1 g/W. Case temperature 42 °C steady and 47 °C peak at 29 °C ambient.

Which propellers and battery does it run on?

26 to 30 in propellers on 12S LiPo, 44 to 50 V. Bench data is published for 26 × 8.5, 28 × 8.4 and 28 × 9.2 in folding carbon-fibre propellers.

How many motors do I need for my aircraft?

Use the fit check above. As an example from the measured curve, four motors on 28 × 9.2 propellers hover a 22 kg quad at 54 % throttle with a 2.7 : 1 thrust-to-weight ratio.

How heavy is it, and what is the envelope?

590 g ± 5 g with leads, ø 92 × 39.5 mm, ø 8 mm shaft. It mounts on 4 × M4 at PCD 40 mm.

Can I download the raw bench data?

Yes. Each of the three runs downloads as a CSV under its run ID, licensed CC BY 4.0. Values are as logged, nothing smoothed or rounded.

Is it NDAA and MIL-STD-810G compliant?

Yes, both. It is designed and built in India by Vector Technics, and every sale ships with a certificate of conformity.

How is the 8015 VTOL qualified before launch?

More than 1 000 hours on the bench and 100 crash-free flight hours before a motor design enters the catalogue.

Can you wind a different KV?

Yes. Same stator and mounts, your winding and voltage, 15 days from metal to prototype.

What is the lead time?

Confirmed on the quote. Motor capacity today is 5 000 a month, scaling to 15 000.
