I currently have Goldberg Ultimate ARF that I am planning on putting a Satio 125 in. I am planning for my next airplane to be the Cermark Pitts and am trying to only have to buy one engine for both airplanes. So my question is will the Satio 125 give the Pitts enough power to get out of trouble and will it fly the plane scale, or will it be a pig and fly like a cub? I am not into 3D flying but I am into aerobatics and IMAC type of flying. I am looking for the airplane to have enough power to be fun and responsive, I don't want it to fly like a fighter jet but I don't want to have to nurse the Pitts though maneuvers. I hope this helps you answer my question. Also this will be my first time running a four stroke. I heard that it is better to mount them upside down verse side ways, is there any trueth to this? Thank you in advance for you inpute.
