8520 Coreless Motor 8.5 x 20mm Brushed Motors + 75mm CW CCW Propeller for DIY Micro QX95 QX110 Quadcopter RC Drone

I’ve been using multiple sets of these motors while prototyping a drone I’m making fully from scratch. They take a lot of abuse from this process since the craft crashes and doesn’t detect motor stalling in its current design. I’ve only had a couple break or have welded brushes from stalling so far.I’ve gotten the craft to lift off at 60g and it lifts off at under half the max duty cycle with a 48g craft at full battery.The motors and propellers are consistent across batches and can be mixed with one another safely.A couple of technical details:Shorted at 3.7V, they draw about 4.5A. This is above their rated steady state current draw of 1.6A but I used some of the motors that I tested like that in a flying craft so they weren’t ruined for having that current temporarily.I estimate that a full set of these motors can generate 120-130g thrust, or about 30-32g per motor.You’d want a craft 35-70g, ideally 50 or lower as mine ultimately were, so that the motors aren’t running above their rating during typical operation. The motors themselves weigh about 20g as a set or 5g each.I paired these with a LiPo battery that is rated to source 10A of current continuously. No issues with that combination so far.

Great motor and propeller combination for the cost. I am using them for a hovercraft STEM project for school aged kids when they come to my place of employment for Bring Your Child to Work Day later this month.

Very very strong motors. **Be careful to keep your fingers clear from the blades**They lift more than expected.

I'm building a little balsa wood model with these things. They have more than enough power for my needs.

I didn't. Dislike any thing I liked every thing every motor work fine

They do not generate enough lift for themselves and the motor wires fell apart in the first 15 minutes of usage.
