The E4 is underpowered for the tight competition in the mod class, our Losi ESC and 4.5 Motor combo served us well and it's very much a situation that the E4 wants more power and Im not sure it won't struggle.
For me it's silly grub screw holding the C hub pins that really lets the default car down. Ive seen some nice gear at wolf's but for now it's a matter of finding more power and seeing what the transmission makes of it.
Fortunately we managed to find a front belt tensioner before this event and it saved us from a sure set of belt failures.
Ultimately the E4 gobbled up the Losi 4.5 and while its by no means a powerhouse, it's been very reliable. Anyone else run mod?
