Yeah Racing RC Ball Bearing Set with Bearing Oil For Smartech Aerohawk Helicopter #YB0101MX
[YB0101MX]

Ball bearings should always be your first upgrades; that reduce
friction for less rolling resistance, and that means higher speed and
longer the running times. Ball bearings hardly require maintenance
and last a lot longer than stock Oilite bushings.

Our Metal Sealed Dinball Ball Bearings have the lowest resistance.
They are manufactured perciously by Aircraft quality stainless
steel. Pre-lubricated with light protection oil, not any grease to
ensure its excellent performance!
