can't really compare Vin'. 'cause when I flew with the 120 I only used the saddle tanks and the UAT. I now fly with a Mueller center tank which adds aprox 40 oz maybe more.

After an 8 minute flight, roughly 1/2 power I'm landing with fuel in the saddle tanks just below the wooden cross piece that holds those tanks apart.

The nice thing about landing at this fuel capacity is the plane feels heavier (much like a fighter) thus providing a more stable platform (less floating tendencies) in the groove. I'm carrying about 4 clicks above idle around the landing pattern and removing 1 click of throttle at a time as I begin to roll into the groove. The throttle up from this setting is good thus minimizing waveoff disasters waiting for the engine to spool up.

so far so good. avg Rpms have been in the low 60's and temps in the mid 500's.

I know David R is routinely flying 10+ minutes and he's using the stock setup for fuel. His flying style is different than mine i.e. WOT most of the flight
