Heres my problem. I have this new edge 540 with a saito 180 and 4 s3305 servos. This is my first truly aerobatic plane, my last plane was a super sportster 40 with a tower 60. SO for the first time i had a large range in C.G. THe range is from 4 1/2" to 5 1/4" now at first i balanced it at 5 and added 2 oz to the tail to get it close to balanced ( a little nose heavy). However when one of my buddies took it up to fly it kept trying to climb. Everyone said it was because of the C.G., that it was tail heavy. SO with much luck and my buddys heart beating a thousand beats a minutes he landed it smoothly. So i thought maybe i had gotten confused about where to have my C.G. so i asked my buddy and he said i wanted the C.G. on the highest number to start out with and then move it forward. So i took the 2 oz. of tail weight off. So I went home put it on my C.G. machine at 5 1/4" and it was like 1/2 lb nose heavy. So someone please help me figure this out. DO i want the C.G. (as a beginner) to be 4 1/2" from the leading edge or 5 1/4" from the leading edge?

Thanks for your help and please respond quickly( I want to fly it tonight)!!!!!!
