I have a 35% yak, 30% yak and a .60 sized, the bigger the better, smoother and more nerve racking, lots of money. I have a much better time landing the bigger one then the smaller ones. Do not attemt a giant, unless it is a high wing and then be careful if you are inexperienced flyer. Like mentioned things get expensive. My giant yak, if I were to have a rough landing it it $120 for prop and spinner and$100 for gear, plus its lightly built so it flies light, brakes easy. And with gas they vibrate like crazy, so theyve got to built knowing this, then every few flight checked, tightend, wood breaks with the vibration somtimes. Like mentioned, fly awhile, get landing experience. Big ones are awhole different ball game, I fly my bigns and go to my small ones and don't give a care in the world because I knoe there cheap, small. So think about all this, and another thing with bigger ones, there usally alot different need equipment, things are more expensive, bigger, more radio set up usally. It was a huge change from my .46-.60 sized then purchasing my biger yaks.
