💡 What is a helical differential gear set for RC cars and why upgrade to 29T/10T?
Helical gears improve strength and smooth power delivery, reducing torque twist in high-torque setups. - They replace stock bevel gears for better wear resistance - The 29T/10T ratio balances torque with wheel speed in 1/10 scale builds - Made from high carbon steel and nitride hardened for long wear in tough RC use✝️
