I like doing things other do not, mainly because I ain't like most others. I think outside the box or try too. You do not have to look like a gorilla riding a golf ball to be competitive. Couple years back I ran a F/X on the US circut using a full sized box frame MTD and finished 4th in points that year. It finished top every race it ran beating the likes of Mike Miller Kevin Penne and Chuck Miller on some tracks. I fit better on a larger frame, it feels better, it handles better, (longer wheel base) and the average spectatot can relate to it more so thanthe itty bitty huffy style chassis which most have never seen. Its as light as any Huffy I have built so far. Only thing left is gear box battery brakes and motor. As it sits in the picture above I can lift it by my self. I won't once its finsihed but the point is a competitive pro-X can be built using a larger chassis.
