Here are the pictures that I promised. There is one view each; looking from the leading edge of the top wing and also looking from the side. I simply used the finger method as stated to balance it out. I found I had to move my battery pack to about under the canopy to balance it out nicely. If you need more weight in the tail, you might just try a heavy tail wheel. I am using larger foam wheels up front and a Klett tail wheel because I fly from a grass field. I hope these pictures help you. For anyone interested I have another one of these NIB I might be willing to sell.
