Interesting - I am curious who has and who has not had problems. I would naturally think it would be a good fit especially seeing all the magazine articles showing how they made their inferno's go 48 - 49MPh....
I do not have one so can't test it myself. I also am not planning on getting an inferno. I would like to get some kind of 1/18 or 1/16 scale truggy for the mamba though. All will come with time.
