I just bought a used SE at a flea market (no manual). I have just read the thread about moving the C.G. rearward for better KE. Could anyone please tell me what the suggested "factory" CG is and then also where you are at right now with your plane. I am an average flyer just getting my feet wet with 3D style flying. Have been flying a Magic and doing OK with that. Also, I was planning on powering this with a .46FX with a Macs Muffler. Will this be enough for good vertical? My other options for power would be an OS .50 FSR or a K&B .61. any recommendations? How about control throws? Any help would be appreciated. Thanks.
