Maybe the AE-1 sucks is but the AE-2 is pretty good. I only got rid of mine because I wanted the features the HH BR-XL offered.The factory Axial speed controller in the SCX10's is garbage - every one I've messed with had the same problem, terrible throttle control.
your rig is sweettt. im slowly turning my emaxx into a monster/crawler. gonna be running an upgraded novak evx-2 for speed and have a separate parallel system for when i wanna crawl it. someday i will have a wraith like yours
