the only thing is when you put it together.. be sure to put the battery pack on top of the gas tank and mount your reciever right behind the gas tank... if you dont the plane will be to tail heavy and you can not control it,,, also be sure to use a 2oz heavy hub spinner nut on it as well... richard

I would definitely leave the space over the tank accesible in case you need to move the battery up there, but there are plenty of Twists out there with the battery and receiver in the proper wing space behind the tank and they still balance perfectly....even without a weighted prop nut. Remember the plan is to keep it as light as possible....only add weight if you HAVE to. There's no way of knowing how the CG will balance out until the plane is totally built. Also, drill the motor mount screws last...that way you can move the motor forward or back to help a little with the balance issue.
To those who have yet to maiden theirs....DO NOT HAVE THE CG ANY MORE THAN 4.5" until you get used to it.
Be safe, have fun, and Twist it up!!!!
