Jerry,

My Fantasy orginally had the dual elevator servos, but has the wing tube in the stock location. I was using the OS140 and a Hyde mount. I had to convert to pull-pull elevator and locate the battery in the nose plus add two ounces of nose weight. My #1 Eclipse had pull-pull plus it had 3.5 oz of nose weight. Definately move the tube back 1/2". My #2 Eclipse has the tube moved back 1/2" and has individual (dual JR DS3421) elevator servos. Same thing, except I only needed 1 oz of nose weight. My #1 and #2 Eclipse fly almost identical.

I prefer the pull-pull arrangement. For me it is fairly easy to set up. In another thread, there is a link about Troy Newman's CF push rod system using a single elevator servo. For this arrangement I would still move the tube 1/2". For the YS140 DZ installations, maybe only 1/4" move would be required. For balance, you can move the battery to where you best like the CG.

By the way, I dinged up my #1 Eclipse at the Temple contest. The fuse repairs were easy and minor in nature, but I had to remove part of my pipe floor pan for the repairs. So,.....................I am in the process of converting the plane to electric. Once I finish fitting up the Hacker C50 14XL motor, I'll start a new post on the retrofit process. Right now I should come in very close to the 11# limit. The weight of the #1 Eclipse before the modifications, including the 3.5 oz of nose weight was 10#-4oz. I hope to compare flight performance of the glow engine Eclipse to the Electric. Stay tuned.
