RE: Large SM Hawk ?
I have 6 flights on mine now. p140rx. I added a 10oz header tank between the UAT and main tank. I am flying 8 minutes with the gear up. If I put around at 1/2 throttle, I have half a tank of fuel at landing. I have flown 3 aggressive flights and I have about 2" of fuel in the main tank and a little air in my header. total flight time is 10 minutes per flight.
P140 is perfect power.
