Hello everyone

I just got a Hanger 9 Arrow trainer ARF kit and need an engine for it. The box says it can use .36 - .46 (2-stroke), .45 - .72 (4-stroke). I was thinking of going with a four cycle but I wonder how it will fly with the smaller size it indicates? Was told the .72 is way too big for it and was recomended a .56 or .62. Can the four cycles do the rolls and loops without oil issues or should I stay with the two cycle? Say a nice .40 or .46 from enya or os. If you had one of these planes what did you use and how did it fly?

Thanks for you help in this.
