I was using a gms 47 on mine, not sure if it is much lighter than the rossi, but it wanted to nose tward the canopy untill i gave it a little down thrust, maybe 1/2 degree. I had standard servos in the regular position and 3 ounces in the tail.
keeping the CG as far back as possible helps a lot. moving the batery or one of the servos is a great way to get the CG back without adding weight. Not sure how inportant it is, but checking lateral ballance wouldn't hurt.
