Against this the few grams that a couple of clevises weigh is not much. I would be interested in how heavy yours comes out at. It still flies very well at this weight.
We will see, a mini hs 81 is on the side in the fuse for the throttle. The saved weight here is put back in w/the dual aileron servo's out in the wings.
No steel control rods, even on the throttle. Golden rods w/the steel rods only from the point it exits at the fuse to keep things rigid. Like you said couple ounces here and there. Hopefully add up.
The other weight saver is the use of polyeurothane glue. I'm not a gambling man but I'd bet this glue is 100 times better than any 2 part epoxy: lighter, sands easier, has a slight foaming property (for minor gaps) as well as the BIG benifit of slight flex. The only drawback is it's a 24hr glue. BUT, nothing a little thing CA won't take care of until it cures.
