yes, single prop engines have a twisting motion in the opposite way of their spin... this twisting motion is known as P-factor and it will cause the craft to try to turn all the time... this is normal and being simulated like real life... the c172p will try to go left... another craft built elsewhere with an engine that spins the other direction will try to turn right... this effect is not so noticeable on twin engine craft... especially those with dual props that spin in opposite directions so they counter each other out...
so, on the single prop craft, you have to always have your controller slight opposite of the P-factor push or, on some craft, you can adjust the trim to counter the P-factor... this trim won't be in effect all the time... only when the wind from the prop is strong enough to actually encounter the trimmed rudder or ailerons and counteract the P-factor...
"You get more air close to the ground," said Angalo. "I read that in a book. You get lots of air low down, and not much when you go up."
"Why not?" said Gurder.
"Dunno. It's frightened of heights, I guess."
