Because the fuse is so long that the paint on the tail surfaces move the C of G farther back unless you are careful. That is the case with one of the new Tucano's I'm helping a Mate fly. After he painted it, the C of G moved way aft.
Strange but true...

Mate,
A well known fact to all the longtime builders of RC planes ............... and surely he has to add more weight to the nose and bring the c of g back to where it should be ????
This is exactly why we need to get the correct balancing point for these birds ............. who knows the wing retaining bolt may yet prove to be correct..............
Cheers,
