Here's another question I get asked very often so I thought I'd answer it right here on the blog...
Question: What's the best throttle servo for my Rampage?
Answer: The stock HX-15CS is a decent metal gear servo but I like the Hitec HS-645MG myself. Unfortunately, I don't sell them here at RampageShop.com but they are available pretty cheap on Amazon
By the way, if you found this helpful, please use one of the links in this post when you order your servo on Amazon and I'll receive a small commission.
Thanks for your support, I really appreciate it.
