Frequently Asked Questions (FAQs)

1. Is a push rod better than a wishbone?

A push rod suspension is a different design compared to a wishbone suspension. It replaces the traditional damper mounting with a rod and mounts the damper and spring in-board of the chassis. It is operated by a bell crank connected to the push rod, which is bolted to the hub. Both designs have their advantages and disadvantages, so it depends on the specific requirements and preferences of the RC vehicle.

2. What are the disadvantages of wishbone suspension?

Wishbone suspensions are generally more complex and impose more packaging constraints compared to other systems like a MacPherson strut. This complexity often leads to higher costs. However, it's important to note that the choice of suspension design depends on factors such as vehicle type, performance requirements, and personal preference.

3. Do control arms affect ride quality?

Aftermarket control arms can have an impact on ride quality. They are often lighter than OEM control arms, reducing unsprung suspension weight and improving the overall ride quality. Additionally, aftermarket control arms can accommodate replacement shocks that offer better all-around performance compared to OEM shocks. However, the specific impact on ride quality depends on the specific design and setup of the control arms.
