Here's a great video by JackOfAllTradesMasterOfNone showing how he modified the steering on his GEN7 Pro to decrease it's turning radius (make it turn sharper) by using some Redcat Rockslide RS10 parts
Here's are some links to the parts on Amazon (I don't offer RS10 parts at TeamRedcatShop.com at the moment)
JackOfAllTrades also mentions in his video that Aluminum Hubs for the RS10 are available but, unless I'm mistaken, I don't believe Redcat ever offered these for the RS10.
Don't forget that I'm always on the lookout for helpful Gen7 videos so if you have one you'd like to share, shoot me an email and I'll post it on the blog for everyone to see.
Thanks as always
