The use of a longer shaft sleeve with larger gears increases the contact area with the shaft by 300% compared to traditional models, significantly improving gear slippage. The addition of a propeller holder makes propeller changes extremely convenient, taking only 30 seconds (requires a 4mm bore propeller).\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eA high-quality brand propeller, the GF5030, is used.
