Powerful and economical - that is what the Quickrun series with its new motors stands for. As a 4274SL G2 engine, every driver in the range 1/8 comes at its own expense, because due to various refinements the engine achieves an ultra-high efficiency. This includes, for example, the asymmetric ball-bearing design. This means that ball bearings of different sizes are located at the front and rear, WAS further improves the load capacity of this already reliable motor. The precisely balanced rotor also prevents strong motor vibrations and a resulting loss of energy. And the Quirun 4274SL G2 engine produces an average of 20°C less than comparable engines with similar specifications when driving. All in all, a good thing!This text is machine translated.
