Team Magic Bevel Gear set
Team Magic have released new, deepened 43T & 13T spiral gears, which are used with the front and rear differentials on the M8 & M1B. Machined on a precision gear machine, every gear is also individually tested and inspected to meet the tightest tolerance requirements. The pitch angle of the gears has moved to 15 degrees to improve power delivery and reduce friction and the new gears also go through a new hardening process to make sure their more reliable than previous versions.
