Fielect 5Pcs DC Motor 3V 14000RPM Electric Motor Micro Motor Round Shaft for DIY Airplane RC Boat Toys Model DIY Hobby

No issues for use on an electronic car project. Used 2 , one powered a fan glued to the shaft, the other a pully pushed onto the shaft.

Motors didn't have enough torque for my application

Last well, work well.

these were just what I need for early Kenner star war ships and fit perfectly'

They are ok for something small like a fan, but not anything else unless you have a watercooled heatsink for it. I attempted to use one of these in a 1/24 scale rc car and it worked for about 15 minutes until I got a warning on the controller that there was an overheating issue, so I stop using it and let it cool for a half hour before I bring it back out. I put it on the ground and hit the turbo button on the controller for a speed run, and while the car was accelerating the motor *CAUGHT ON FIRE* then siezed. I lost my whole 100$ rc to that motor.

Used six to power a 6x6 small RC truck. Power seems acceptable, they all worked first thing. 5 of the six started falling apart after first run. The gearcase screws loosened, and the gear case to motor( which are inside) screws loosened. This causes a disassembly of the gearcase of about 6-10 different gears. Not easy to reassemble.

Fit perfectly, bought it for a RC car. Worked great.

These are great replacement motors for many applications, such as fans.Much Higher power and radically higher efficiency than a really cheap motor!
