For: Tienly GT-45000 RPM Ultra Torque Performance AEG Motor (Long)Product Information:
As previously mentioned, this motor is incredibly powerful. So much so that you shouldn't consider buying it unless you're willing to switch to LiPo- it will take 30-45A *rough estimate due to ammeter not tracking accurately* to spin it to full speed depending on gearbox. If you've got a NiMH battery, it probably won't have enough output to operate the motor. I'm feeding mine with a Matrix 11.1v 25c 4000mAh LiPo.
The motor runs cool, although the cooling can be improved by removing (might void your warranty) the stickers on the sides. They actually cover 25% or more of the intake port because they're probably stuck on crooked like mine.
The connector tabs are kind of irritating to plug into, they're too close to the brush spring post and make insulated wire ends difficult to connect fully. If you have ring terminals, the screws that hold the case together (not intended to be removed obviously) are pretty difficult to turn.
The motor is VERY stiff to turn, the magnets they used could potentially open a miniature black hole and alter physics in their immediate vicinity. Be careful to not stick the motor on a desk with any loose iron/steel tools, they'll be attracted to the motor case with a vengeance and may cause injury. (the Airsoft GI video of this holding up dozens of tools is for real)
The extension bushing/shield is nicely machined and has quality bearings supporting the motor shaft, unlike cheaper OE long types that are just a bushing on the shaft.
Can alter the laws of physics (take that, Newton)
Incredible amounts of torque
Runs cool as a cucumber on 11.1v
Quality fit and finish
Direct powered brushes (has braided copper wire connecting brushes instead of relying on brush guides)
Keeps all your tools in one spot
None, aside from needing a warning about high magnetic engagement force. Watch your fingers!
