I'm also in the final stages of building the voyager. Seem to be a good quality plane so far. I also noticed last night that my OS .46 FX is making the plane very nose heavy. Even with the motor pushed back to the firewall, I had the battery sitting just ahead of the tail to get good balance. I'm going to get a light weight motor mount today and huck the heavy clamp style that came with it. Since I want to keep the plane light as possible, I'm going to look at mounting the battery in the fuse towards the tail. Cutting a hatch should be pretty easy.
