Everything that's been noted so far in this thread will work out just fine. I would like to say that most peole will make their planes more complicated, heavy, and expensive to set up and fly than they need to be. The new designs from Wild Hare were and are intended to be as simple as possible to set up, and to make the installation process for the user as pain free as possible. Most of the Wild Hare planes are designed to balance on the money with the tanks forward of the wing tube. Simply moving the batteries around a little sets the C/G most of the time for any type of flying.

That said, what you guys want to do will work in almost every application. If you meet the minimum servo requirements for the plane, and power those components with a 6 volt 1,800 mAh battery of any type, you'll be good to go. As in anything else you should monitor your batteries and not simply trust they are large enough to fly as many times as you want without checking. After the minimums are met, everything above and beyond is all cake and just makes for a more enjoyable flying experience and sets the stage for bigger and better things later.
