I have tried different pipes and plugs as well as different venturies( 8,7,5.5) but i can't seem to get more than 8 minutes on a tank. 7 seems to be the best venturi though...it gives 30sec more.
I run 1/8th buggy and a Sirio STi engine.

I'm about to try 16% nitro instead of 25% i run now.
Has anyone tried this and has any input on the results?
Power wise i don't think i'll have any problems since it's already overpowered so if someone has tried it i would much appreciate the info.
