I have a ZDZ 100 in my H9 Sukhoi31 and the plane is awesome.
I put the two elevator servos in the plane as far up front as possible and 2 rudder in the tail and I didn't have to add any weight for balancing.I have two 1850 6v packs nimh 2AA ahead of the wing tube. The plane weighs 23lbs and blasts out of hover.
It's a good combo and I'm sure you will like it.
