I was shocked to notice that the Reventon Pro is too wide to fit onto the chassis of my B-Max2. The LRP SXX and GM Genius Race R series (also available from Vampire Racing, Yokomo and maybe others) are a tight fit already. Fortunately there's way more room in a 4WD...
Oh, and I've got a Competition 3.0 related question: I fried my 7.5R in my 4WD buggy some weeks ago due to unknown reasons, and a club member's motor went up in smoke during the German nationals last weekend. Might this be caused by a bad connection due to the plugs becoming looser in the course of time? I've been a big fan of the Competition 3.0 motors, but chose a motor with solder tabs as a replacement due to my suspicion.
