No disrespect here, but smcqueen89 I think you need to realize as Mafia has pointed out, that a lot of the users of the forum here, esp Roy aka "Mr RB20", have been playing with these cars and motors a lot longer than a single post can show. Reading between the lines sometimes means taking advice for what it is, without question. No one tries to re invent the wheel to do something different. People are letting you know their experiences of what and where to best spend cash. Turning around and having a go at people for their age or experience isnt cool, but as a guess by your own username, people have been playing with these cars while you were still in primary school.
At some point when you want real advice, and dont want to try argue something that has been done to death, then the people who know best wont be giving up that advice so easily.
