Whoa.. cant believe its been more than 6 months since I replied.....
This year local race has been called off. Been slacking lately
I havent been flying the pylon for a while, except this apst two weeks.
Using old 46fx with asp liner, ran 9x7, with about 10% nitro and got about 15300 rpm.
I think I will just stick with that 46fx, and practice to tidy up my flying for better consistency.
