This engine has tremendus power. USing on my RRR and i am really happy with this. 15% nitro is what i am using since i was in the break in stages. Got to really run it lean it and all that.....with the new gear combo i got wanted to see how fast this could really go !!
But 1 thing ..... 3 tanks off idle and 7 tanks on the ground a total of 10 tanks is what i have to do to reach a stage of complete break in
just be careful and patient... while doing so.
