Ran up the engine today. Had a leaking fuel pump last weekend and rcgfusa replaced it asap.
Also found out that the rcxcel tach does not work with the new rcgf ignitions.
Fuel is Shell mid grade,Stihl ultra HD oil mixed 30:1.
Stock plug.
13x6 apc prop I got 10000 rpm on the fourth run of the engine.
Outside temp ,55 degrees fahrenheit.
No thrust data ,seems to pull well though. I need to get me a fish scale. Lol
Have a Xoar 14x6 pja on its way.
