Tonight I got my yak out to see about this taching thing. 50 degrees out it ran 6900rpm but on the pull scale it was 25 pounds. So it must be my xoar prop, it loads it down alot. O, also my j-tec muffler was loose. Good thing I got out my plane. That would've made me real mad at the field. How do you guys keep that pipe tight? I tried blue lock tight last time.


And to all about the temp of the motor running at 2500rpm for about 15min. It wouldn't go above 139 degrees.
