Anybody can install 15 servo's in the most convenient location, but figuring out the linkages of minimal servo's as far forward as possible is an awesome challenge. Also knowing how strong to build something without adding excess weight is an art, it's the engineers art.
Luke - I completely agree with your comments above....but my point was not to promote excessive use of glue, building without regard for weight compromises or anything else for that matter.... there seemed to be a growing fear of final weight with the CMP 120 Zero...and my point was to not be afraid of a 17 or 18 lb Zero just because the box suggests 12 lb. It's a great flying airplane, period. I also really enjoy the building/engineering aspect and...strange as it may seem, my CMP Zero #1 is my first ARF in 33 years of flying RC...(my Zero #2 under construction is my 2nd ARF[8D])...and the "builder" side of me evaluated what I liked and didn't like about #1 and made the appropriate changes on #2, including glassing the wooden structures, beefing the gear mounts, adding flaps, (1 servo), changing from the A6M5-32 to the A6M3-32 and enlarging the elevator surface area 20%. Unfortunately, I'm too far along on the build to incorporate your tailwheel...That woulda been cool.,,,but I'm still toying with the idea...

...and like the tailwheel, there have been volumes of great ideas shared on this thread, (thanks Zero322 for starting it!),
Misha - Thanks for the cockpit link and file...too cool...love it!
