The new aluminum middle shaft mount for the Team Magic E4 chassis replaces the standard plastic part and is designed to improve durability, performance and looks of your E4.
With the introduction of high power brushless motors, getting the transmission of an electric car to be light and efficient but also remain robust can be a challenge. From many years of experience in the R/C industry, K-Factory has developed many high quality hop-ups and this new middle shaft mount is no different. The aircraft quality 7075 aluminum is machined to perfect tolerances and provides increased transmission efficiency thanks to reduced flexing during high load acceleration.
Replacing the plastic with alloy means the new part is extremely strong and any chance of breakages from obstacles or other cars is a thing of the past. The use of alloy also means that any low stress areas can be removed without affecting the overall durability of the product.
