Receny picked up my first crawler and am loving it! It's the RGT ex86100 v2 and for my first crawler and experience driving one I'm blown away how well it does. Have done some upgrades and made adjustments to my shocks and added weight and have seen huge improvement already. Here's my build thread and what I've done so far https://www.rctalk.com/forum/threads/first-crawer-build-rgt-ex86100-v2.131892/
