With a ZDZ 60 the plane comes in at 23-24 lbs depending on radio gear and batteries. With the ZDZ 60 I have to put all batteries on the motor box to get the ballance at the rear of the CG range. (1- 2000 ma 6 cell on ignition and 2- 2400 ma 6 cell on radio). I am not sure of the weight difference on the ZDZ versus Saito but I would put the rudder servo on a pull pull and move it forward to help with the balance. I am using 1 HITECH 5945 on the rudder and can do knife edge loops so I am not sure I would add the second servo to the rudder and save a little weight there.
