Mini-Review

Bernoulli 3515 500kv Integrated Motor with ESC and Led Light


Hello, this is my test and review about new Bernoulli 3515 motor from Inspired Flight.

Bernoulli 3515 500kv Integrated Motor Built in ESC & LED light - Thrust Test and Settings (12 min 36 sec)


First impressions:
- Really nice build quality.
- Super smooth bearings.
- Bright LED,
- A lot of accessories,

I need to know about the motor in real flight situation, not only the max thrust in perfect lab situation.
So my test using partially charged old batteries and 1447 carbon fiber props.
I think this represents a motor performance: in the middle to the end of the flight.

Test result with 6S batt + 1447 props:

- 770g (40%, 4.19A)
- 890g (45%, 5,36A)
- 990g (50%, 6,16A)
- 1090g (55%, 7,25A)
- 1220g (60%, 8,72A)

Its safe to say 900-1100g = recommended weight per motor. (1200g should be no problem in calm day situation)

Based on 8 minutes test, temperature never reach 47C, so motor capable to use bigger props if more thrust needed.
Unfortunately I don't have 15" and 16" props. I just have 12", 14" and 17" to test with the motor.
I will post my test with 12" + 6S later (maybe 17" with lower batt setup)
