Amazing video as i just got my first nitro slash 3.3, I may actually aquire some of these upgrades before ever even breaking in this engine. I want it to last a long time. Thank you for being very informative explaining everything so clearly and detailed.

Just make the investment and buy the O.S. 21 TM

I want to change to a o.s 11k carb, but how do you tune the extra screw?

So one watches too much 404 lol
