Redcat hasn't released a parts list or manual for the upcoming Marksman yet but, from the information and pictures currently available, it looks like the Marksman will utilize the XR247 axles from the Wendigo.
These axles have proven to be very durable in the Wendigo and, aluminum upgrades are already available if you want to take your Marksman to the next level.
Once I have 100% confirmation of this (I'm sure I'm correct), I'll start to add the axles, parts and aluminum upgrades to the Marksman parts page if you'd like to order them in advance of the trucks arriving.
Stay tuned for more Marksman details as they become available
PS, did you know that TeamRedcatShop.com is just a one man, small business? People often confuse me with Redcat Racing but I'm just a dealer of their products. When you buy from TeamRedcatShop.com, you are buying from a fellow hobbyist with a passion for RC cars. Not only will you be supporting a small business, you'll be getting a better deal than if you buy direct from Redcat. Please tell your friends
