The 1/5 Trenchers are for my converting to BL Losi 5ive T. Didn't want to wait on Traxxas any more to come out with a 1/5 off road truck. I'm not going to run them on my Revo, to heavy, I like my 3.8 Badlands. My buddy has a HPI Baja he has the 1/5 Badlands, looks like they might be a good fit. Still a little bit heavy for a 1/8 scale truck..
I can see how the extra weight would stress the stub axels. Interesting set~up on your Maxx, looks good..
