RE: .21 engines in Truggies
My friend has a GO .21 5-port in his Caster K8T and is has a ton of power down low and is SMOOTH. I might put one in my Caster but am thinking of a 7-port in my buggy to put in my truggy and put the .21 3-port in my buggy instead. I have a GO .25 in stock but I do not know of anyone who has tried it yet.
