Better than the other brand i tried, here's why:
5 Stars
Better than the other brand i tried, here's why:
Firstly, for $10 at the time of writing this, it's a great deal. Especially when considering the props that come at no additional cost. So that's a plus.I ordered two different brands of 8.5x20mm coreless motors. The first kit that arrived, had no jst connectors, but extra length of wire compared to hobbypower. HP did come with connectors though and a short length of wire.Where the HP motors seem to be best is the balance felt while operating the motors and matched power output. The other brands motors vibrated pretty hard and i decided not to use those at all because of it. i tested them all using AA battery while holding the motors. That's when i felt the hobby power motors were better due to lower noise, better balance and fair price.Only negative was one prop had too big a hole to fit the diameter of the motor shaft. Had to use a dab of crazy glue, no big deal though. Also, could've sworn two motors weren't operating in the correct direction, but i switched the leads and was good afterwards. I was confused at first with too many motors in front of me and scratching my head trying to figure out why i still had all 4 motors going CW.

4.0 out of 5 stars Great to use for Capacitor Powered Model Planes
Reviewed in the United States on March 16, 2020
I have used several of these to convert Hand and Catapult Launches Gliders to Capacitor Powered motor gliders. See my video at youtube/jimeagle1 in the model planes section.
