The Turnigy specs out with more power, but is heavy. The PZ 480 is already too heavy upfront, which makes the plane less agile and fast in the glide so the elevator can create enough down-force to raise the nose end of the seesaw.

After the ST .10, I taped up my flaps and pulled out the extra servos. It glides and lands nice and slow. Another 2-3 oz of weight gone.

With the 1800 battery, a 10x6 and 60% throttle, you have the same power plus longer flying time than stock. That's another 2 oz saved by hauling around less gas.

Like any airplane, any weight savings leads to more weight savings; the rich get richer. So even before applying full throttle, you've decreased thrust required by about 6 oz, or 20%.
Seems to me that Super Tiger motor is getting really bad reviews from one of the motor testers here on RC Groups. I'll have to find it and post back the results. From what I understand, it's way over rated.
