I cant wait for one this xmas.i am going to mount my satio 150 in it.not because of any special reason ...its the only satio I own that will work my 180 is flying my dynaflite pt 19. And the other four stroke is a 90.from what I am reading the 150 will likely need less weight up front.and I will reinforce the firewall.i do anyway with arfs.and a few other places.originally I was going to go electric but seeing bobs flyin video with a 125 convinced me otherwise.i love the 4 stroke sound.have been flying electric but somehow on a warbird it jus isnt the same.
