OK Coco, cool. So what do you need to do to the 125? You should get him back in there asap
I have no experience with Armatus at all, only pics and videos. And I have only owned a small ATF.
However, they are extremely fast, flighty and nervous like an Acestro. And absolutely they need a pretty big tank, even small ones.
Simply from videos I have seen, Armatus look a lot less flightly and nervous, they look quite calm actually. So from what I have seen I would agree indeed.
To be honest, that's one of the reasons I am veering towards Armatus rather than GATF, as until I buy my own place I can't get an enourmous tank.
