Not to be a smartie-pants, but why not put it in a $6 flat-rate box and mail it. USPS will even deliver door to door in two days for that. Less than the cost of 2 gals of gas.
That is probably where we will end up. But it doesn't hurt to try. I have been involved in some of pony expresses and it usually turns out to be a nice thing to do for someone and I often get to meet a new WW or visit a new shop .
A No.3 sized plane will not fit in a small flat rate box. Even if it is taken apart. There has to be enough room in the box to allow for padding, bubble wrap, styrofoam, etc.
Salem-
USPS make a thing called a "regional box" you have to order them on-line but they are REALLY cheap especially shipping a light thing a short distance (regionally)
