4Pcs 6mm Flange Coupling Connector, Rigid Guide Model Coupler Accessory, Shaft Axis Fittings for DIY RC Model Motors

Exactly what I wanted, and it arrived two weeks early.

Made new extensions for long selector, volume and tone controls when plastic coupling broke. They work well

Le paquet est arriver avec seulement 2 flange et il manque les visses de blocage !

All 4 couplings were not 4mm. They were about 3.6-3.7 mm, which meant my 4mm shaft didnt fit. Probably defect if others got the right size.

To small application

Needed this flange for my generator throttle and shut down linkage so I could add a remote linear actuator . No more getting in and out of the engine room to start the generator :)

Me gusto los tiempos y el producto es de excelente calidad.

The product is good (8mm flange) but the package is too fragile, arrived broken (the packing bag) and the lock screws were missing, they probably fell off the box because they were not screwed to the flange and since they are very small they fit between the box gap.

Description claims that they are heat treated steel. However they are easily drilled and produce a shaving consistent with the cast iron. Spark test also points on the cast iron. Shaft holes are not rimmed and not very accurate. Flange is OK for a non-critical application. I would not use them for a hi-RPM applications or for a powertrain.

Un peu petit et les trous pas filté
