So your saying with alittle modding you can use a EZ60 in 8th on 4-5s? Sensorless of course. Using 10th scale esc for 8th youreally wouldnt need sensored the throttle comes on so smooth from them for some reason. JSR if I ever come up on a 60 dirt cheap I will have to send it to you to do your magic to it. I have to say I would prefer a nice bec though, but i could always use an external if I had to. If tis ends up being cost effective lots of guys will be doing this. Now whats this thing I been hearing about guys runnung 5s on the 80EZ's? Are they modding them?
