Delay of Overseas Postal Services & Postage Adjustment Hello Valued Customer, Due to the worldwide epidemic our long time mail partner: Hong Kong Post's services has been affected greatly. Rest assured, we have sourced several other courier methods, and hope to send all orders to all our customers around the world. Even with the new courier methods, shipping times will have some delays, hope you will understand that during these difficult times due to reduced flights no courier can function as usual. Sorry for any inconvenience caused.
For Engine Use (Hobao / OFNA Hyper 21 Engines, SH Engines)
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 Yeah Racing Ball Bearings have the lowest resistance. They are manufactured perciously by Aircraft quality steel. Pre-lubricated with light protection oil, not any grease to
ensure its excellent performance!
