GP Easy Sport balance.
I just finished assembling a Great Planes Easy Sport with an OS 46 engine mounted as per the instructions. A 600 mah battery mounted right behind the tank and the RX behind that. Now in order for it to balance at the 105mm called out in the instructions I would have to add 3 oz of lead to the tail. I've been doing this RC thing for 40+ years and I know all about moving stuff around , that's not the question. The question is, is this just a short coupled poorly designed model or am I missing something else here. I'd really like to hear from someone who has assembled this model.
