Funny you should ask, I am going to be working on a video of the full 2024 rebuild of this unit I bought back in 2011 when it first released. However, since you asked... Spektrum Firma 60A Brushless Smart ESC / 2100Kv Sensored Motor Crawler Combo, SPMXSEMC08. I will go over it in more detail when I do the video, but as you can tell in the footage it can slow crawl with the best of them, but has gobs of wheel speed if/when you need it. Good luck on your Wraith brushless conversion!
