Unfortunatly I dont have radar and GPS I hoped that RPM sensor is accurate.
so Brian as I understand I need calibrate it?
I try figure out proper RPM using Prop Tacho, My friend have it...
Buy now I charging my battery and will try out it on load. Lets look what amps is going through maybe i will figure out why my 9XL run so hot? Outside is now perfect day for test Dry and Cold :) only 43F
