tjmax, what is this power valve youre talking about?

 

i know a kid with a bayu 220 and a friend with a recon, I belive just about the same engine as the 250ex. The 220 is definatly faster top speed ive seen that one but i dont know it depends on how long the drag is. my buddy with the 220 has a half mile grass airstrip so we always have plenty of time to get up to top speed to see who is going to win. also a paved road next to it we like to scream up and down
