where did you see any redcat advertised as 80mph?
I just clicked on several models on their site and none have any advertised speed rating.
one issue redcat has that hurts their name, is greedy dealers. some jack prices way to high, others use false advertising, some sell the stuff but have never run them and know little to nothing about them. ive seen a few brushed redcat models in ebay ads said to hig 35mph (not gonna happen)
IMO redcat should advertise some of the top speeds of their models. the mirage out of the box on stock battery does 45mph, which is not bad at all. on 4s it will do 59mph, which is nuts for a $300 RTR 1/8 scale 4wd rig.
