Hi Patrick,
To answer a question that hasn't been answered:
You don't want a DD S400 motor on a Slow Stick. Direct drive is for fast airplanes and usually uses a 6x3 prop. You need the geared EPS 300 motor and the larger 11x8 or 12x6 prop.
Balsa Products has a good supply of GWS stuff. Try looking here:

I bought a second "parts" kit also. Really comes in handy.
