Not bad. Now if there was something that would allow a little adjustment up or down depending on how your motor is mounted. But that's kind of what I had in mind to keep the rear of the motor from moving around.
Using the motor as a chassis brace?? I rather have them "floating", to allow for some chassis flex. Needs sturdy motormounts, that's true.
Well, I can tell you what I did on my last truggy was to simply wrap the rear end bell a couple times with some narrow electrical tape. Can't even see it on the Neu motor. What that did is allow some kind of cushioning at the rear of the motor so the chassis wouldn't get all beat up. That's probably all I'll do for future too. Just thought it would be cool if there was something else out there that didn't look as ghetto.
