Hey Crashburn, a couple things I should have mentioned, I modified the reciever/battery tray to accomodate the elevator and rudder servos and mounted it right behind the fuel tank, essentially moving it forward one bay in the fuse. Also I put the battery on top of the fuel tank right behind the firewall. If you haven't already cut your pushrods to length, they are long enough to let you do this. I used a mini on the throttle and built a mount for it on the side of the fuse. Instead of the stock pilots, my 9 year old was good enough to let me saw Barbie in half right at the belly button and she sits in the rear cockpit. All these little things add up to a plane that balances with the 91 and 3.75 ozs. Good luck, let her fly on the wings and enjoy!!
