I had a radio "mishap" and put in my Hangar 9 Aresti that had an OS .46FX in it. The Motor survived the mishap fine, but now I am torn, I loved the way the Aresti flew with the .46 on it, but I am looking around and just checking as to what's out there for that powerplant. I like the solid way the Aresti flew, wind hardly affected it and it went the way you pointed it like it was on rails. I am also interested in a good 3D style machine if one could be had with a .40 sized engine.
