RE: Balsa USA Citabria Pro
Mine has a 1.60FX mounted in the nose and balancing that required putting a pair of Hitec 605's in the tail. Mounting the servo's in the tail took a bit of engineering but I think it was worth it.
With a 1.08 FSR I can't imagine you needing weight in the tail to balance it. An idea I used to get a bit more weight back in the rear was to change the flying wires from the supplied 2-56 rods to 4-40 with metal tabs and the du-bro solid ends with screws, seemed to add up to a couple of ounces which helped in my case. The strength was also appreciated during the lerning curve with this plane as I flipped it over a few times getting used to it, and mine is the "new" redesigned kit that isn't supossed to do that.
One change that made a HUGE difference in the way mine flies was to put the Cline fuel regulator on and move my tank back to the CG. This got a bunch of weight out of the nose and really helped smooth out the take offs and landings, and eliminated the nose overs.
Mine weights in at 13 lbs with the 1.60 and flies very good. With your 1.08 it's gonna fly ok but I bet the airbatics won't be very "pro" unless yours weight a LOT less than mine does! Either way it looks great in the air and very realistic.
The C-pro needs a lot of aileron differential for smoothing out the turns, otherwise it has one of the worst cases of adverse yaw you have ever seen and needs a LOT of coordinated rudder just to turn it.
