I have just finished my Bling with a DA50 on it. I put my receiver, batteries, etc per the plans. A friend and I tried checking the CG by putting a finger under each wing. It was extremely tail heavy. What I would like to know is how do you accurately check the CG on a large model? I can't believe it is this much out of balance as the plane was designed for the DA. If the method I used is okay is it possible the CG on the plans is wrong?

Thanks for any help.
