So I was fooling around with the F-86 turbine last night, and stuck a 43 lbs AMT-Olympus on it for gits and shiggles. I took it up to about 4000 feet, and pointed it straight down. At 400 MPH, it stalls in the air, and slows to 100 MPH. I also wondered how deep into the ground I could go...-56 feet so far. [8D]
