No No I am not telling you not to get it. I am just saying it is really big. And I have never seen a CRT.5 in person so I have no idea how much space is there. The ESC is great from what I've heard and I would get one but space in my Revo is tight, and until I find a good out of the way place to put it I am not going to personally get it. Just look at the size specs of the ESC and make sure you have sufficient space. It can fit in my Revo, I am just a bad driver and worry about flipping and it being crushed since it would be the highest place on the truck... I will probably get one once I start my Terra Crusher conversion(or if I start it... Unlikely right now). The 80A from what Ive read is more likely good for over 100A. I would recomend it to anyone just from what ive read about it...
