You have to keep the original gear and tail skid. Yea they're a pain in the ass but anything else is blasphemy.

1) Move tank to CG - Cut out servo tray where throttle servo would go. Open up the center former just enough to slide the tank back to the fwd servo.

2) Move Battery aft - Mounted a flat pack to the bottom of the wing as far aft as possible, with servo tape and a rubber band mount. It will clear the servos by 1/4 inch. (Actually had one of the club "ancient ones" complain that it was Jun. If the wing came off I would loose control of the radio..... riiiiight, back to your nap)

3) Throttle servo - Micro 55 zap goo'd to the side of the fues ahead of the tank.

4) Reinforcements - Thin CA'd every piece of bare would I could get to. My first magic fues broke in flight. Don't worry about the firewall. The vert could use some wires but I am too lazy, no problem so far. Used stock pull-pull rods they work fine. Pull on a rod or pull on a wire, can't see any difference.

Started with Rossi .45, too heavy too much power. Wouldn't hover, lousy throttle response at 1/4 throttle. Went to OS .32sx. Perfect.
