  • These couplers are strong and well built!

    posted by daver18qc

    -These 4x5 couplers are well built-They have tight holes that fit your shaft well(no "pun" intended lol)-Can be used for a variety of projects-They are strong enough for 1/10 RC use
    -You can build yourself a driveshaft that goes direct from a standard 1/10 RC 540-can motor's shaft with the other model couplers (3.175x4mm) to a 4mm rod and use these 4x5mm coupler to output your motor directly into a transfert case without any need for a transmission!-The set screws have plenty of thread to bite into.
    Buy these with confidence, good quality, good finish, tight tolerances, just enough slack in the joint to make them smooth
  • Car Wheels

    posted by NektariosSp

    Good item to buy for little DIY projects, involving micro-Controllers, R/C games and others. It runs quite nice, with low voltage (e.g. 2.5 Volts DC) as well as much higher voltage (e.g. 8.0 Volts DC). Ideal for quick installation for micro-Controller PWM controlling little cars.
    Another model should be available as well, with a much higher rotation reduction on the wheel output.
    Good buy, but the rotation speed is too high, for my project at least.
  • Good, but Quality Control Slpped up Here

    posted by xxup

    Well made with minimal free play on the axles. Not suited to high speed operation, but fine for slow RPM applications.
    Leave out the Allen key. It is not really necessary as most people will have one in their tool kit. Alternatively, offer to sell the correct size one in the "other people bought these also" section of the product page.
    Great product. I will buy it again.
  • Electric Motor w/ Propeller / Fairing for R/C Model Airplane

    posted by Roskata

    The price is good and the quality is also good.The propellers are CCW (counter clock wise) and CW (clock wise) which is usefull if you want to make a nano quad copter.The thrust is about 7g per motor at 5V with the provided propellers. Current draw is about 300mA per motor.
    They could be usefull for hobby projects.
    Probably I will order another set to try to make a small quadcopter.
  • Connect your motor the right way

    posted by Lieuwke

    Perfect coupler for SKU: 91625 or equivalent types DC motors with the same shaft. The screws and wrench that are supplied with the product make it very easy to make a good connection and a sturdy fit. Finishing of the product is very nice and the copper can be drilled in easily also, so adjustment of the shaft is a possibility.
    Connect your shaft the right way!
    Not a very exciting product, but if you need a shaft coupler this can help you out!
