Default RE: Proctor Mini Anti-Bipe (with mods) Build Thread

I finished the wing rigging and left one crimp on each wire lose so I can make final adjustments after it is covered. I also cleaned up the brass center cabane struts by rounding the ends and sanding off the oxidation. Instructions call to paint these black but I think I'll keep them brass. There's a product called Blacken It that I've seen used to blacken brass parts to mimic a weathered look, so this is tempting but it's not available locally. Now I just need to add some hard points in the wing for holding the wings together.

I also commited to putting servos in the bottom wing (ripped out the turnbuckles). I have a couple old Futaba S133 micro servos which I think will be suitable. They're not fast and they only produce about 28 in-oz of torque, but I think would be good enough for this model especially given it will be electric powered and the control surfaces will not be vibrating wildly making it difficult for the servos to hold center. I'm also rationalizing this choice by thinking that the servos used when the Antic first came out probably had no more than 40 in-oz of torque, and one was used for all wings. So 28 in-oz on each side gives me a little more.

Crashing on a big proposal at work and sick kids have been making it tough to find time to sneak into the workshop, but I'm so close now I'm going to keep pushing through the build even if it is cutting one piece of wood a day. This is pretty much how the entire build has been going anyway, slow but steady...
