    Hi guys I am building my first ARF and have it almost finished. I am using an electric motor and 3s battery as I have that in my kit so the guy at the model shop gave me the biggest about 620 with an 11/5 prop I think. I put the marks on the wings for CG at 86 and to my horror it fell backwards...
