HOBBYWING QUICRUN 4274SL 2000KV BLACK G2 MOTORPowerful and inexpensive that's what the Quicrun series with its new motors stands for. As a 4274SL G2 motor, every hobbyist coming across the 1 8 scene gets their money's worth, because the motor achieves an ultra high efficiency due to various refinements. This includes the asymmetrical ball bearing design. This means there are different sized ball bearings at the front and rear, further improving the carrying capacity of an already reliable engine.
