Careful, the bigger the plane the bigger the motor and servos need to be.

When I built a kit, I took all the parts and sanded them down to half the thickness before removing them from the die cut sheets. Used a palm sander on a very flat surface. Then I would put ultra thin CA superglue along the open grain edge of the balsa letting it wick into the wood. It is amazing how far through the balsa the CA would wick, most parts you will see the grain on the opposite end of the part get wet/darker. Then wet it with CA accelerator mist to make sure the CA set. The result was a Balsa Acrylic Composite that is lighter and stronger than the original balsa. It would also join much stronger and with less glue to other parts since it was already saturated with glue. A typical 5lb 40 size plane given this treatment would only weigh 4lbs when built, very significant with much better flying characteristics.
