got the sd-models extra 260 today, this thing is HUGE! This is my first giant so bear with me.
I've read all the posts here and still want to clarify things out. I know to run the engine for 2hours @ 2500rpm, 2hours @ 3500-4500rpm, my question is: is it using needles' factory setting? That I can only adjust/tune the engine after 4 hours or after 2 hours if I decide to fly the plane after the initial 2hours @ 2500rpm.
It's a shame Bob P(the guru) doesn't have a DL engine and is not quiet monitoring this thread anymore...
