I presently have the following engines at my disposal: Saito180, YS120NC and YS120SC(I think). I just tached the two YS120s on YS20/20, APC17x6. With the NC I got 8800 rpm, with the SC I got 9300 rpm. I don't know what the Saito 180 would tach at. I have the Saito180 in a Cermark Pitts that I want to sell, but I don't know if I will sell with or without engine. One of my YS120s will go in a Jerry's Spoiler, and I want to get a 120 size Katana S. My question is, are my YS120s strong enough for unlimited vertical and 3D on 11 lbs planes, or should I keep my Saito180 and expect better thrust from that engine? According to the Thrust HP Calculator I am in the 19-22 lbs thrust range, but I know this software is a bit on the positive sidie he he.
I am asking because it would probably be easier for me to sell my Pitts with the engine.
