My TT has run for three gallons since purchased 5 months ago.
Now it turns:
Temp:18 degrees C
ASL:0(I fly at see level)
Prop:12.25x3.75 APC
Fuel:20 nitro/22 oil Felix pattern fuel
RPM reading:12.150 peak
But richening to 11.500 for take off.
Pulls out my 4.2 lbs TT 3D spirit very well from a hover.
