Here's my .02 ---
I've been flying pattern about year now and just moved up to a larger plane ( Vortex ) with a YS120FZ.
A few things re: the previous posts-
- I don't think it's a crank shaft issue with YS's. They are pretty solid.
- I know at least on my plane, it is very clean, ie little drag. Combine that with a 15x11 prop, and even at idle you have significant pull. I kill mine when I am about six feet high and have just called "LANDING Beginning Now ". If I don't, yes I can fly it down to landing, but it will roll out off the opposite end of the runway.
- My aircraft does not steer well on the ground either, as someone previously mentioned.
- re: banging the prop - Well, they are $12-$16 a whack.....

Haven't banged one in some time, thankfully. Usually happens in the pits with me as I lift up the tail.....
