Default what size battery pack

First let me tell you that I have a 1/3 scale supercub that I built from scratch. It is powered by a 52 cc quadra. I have dual batteries and dual hd switches.The battery packs are nicad sanyo 800 mah 4.8 volts. this setup should give me 1600 mah for seven servos. The servos are. 1. standard for throttle. one 70oz servo for the elevator. one 70oz servo for the rudder. and four 100oz servos forthe flaps and areilons. am I right in thinking that a 70 oz servo will give about four and one half pounds of pull or push? and will the 1600 mah be enough to fly this plane in a scale way? the planes dry weight is 32 puonds. what do you think?
