Recently I picked up a near new ECX Boost for 60 dollars. I took it for a test at my local Rc track and from what I have noticed it is to underpowered for the track. It also has alot of slop in the steering. From what I've read the RPM steering upgrades are the way to go but what is a good motor/esc upgrade. I want something with more grunt. I'm running it with my 2s lipos but I would like to up this to 3s. Any suggestions would be great thanks!
