is the waterline cg the balancing of right to left?

", the wing trailing edges need to be beveled to 45 deg to allow spoileron travel of 45-55 deg throw for harriers,wall" i have no idea what that means.. And to tell the trueth not sure how to beef up the landing gear. wish someone had pictures..

got the 4/40 push rods and clevis to solder on(actually one end is threaded) would it be better to just put a z bend in rather than solder? Not confident in my soldering although i did pick up some siver solder and flux...

U told me I could ask.. open to anyone and everyones thoughts..
