[WWI] Added:Pfalz D.XII - Free Flight

[Steven Perry]

> T for Totally envious.  I have yet to get a stick and tissue model to fly
well.  Oh well a goal for the next decade.

Never had much luck with stick & tissue rubber power FF other than a few
peanut designs. I built a Baby Ace with CO2 power and it flew beautifully.

The surge and fall off of power from rubber seems to always leave the model
nose up and stalled or nearly so. the CO2 power is more even and makes the
models much easier to trim.
