I chose the electric version, but whichever you prefer, you won't be disappointed with this kit. Everything comes neatly packaged and grouped in a sturdy box that protects the parts from shipping damage. This is where it all begins. Sizes are clearly marked on the plans, and all you'll need is a razor blade and some sandpaper. There are a lot of angles to cut as you fit the stringers, so take your time and work carefully over the plans to be sure you make matching sides.
Construction is straightforward.
That doesn't sound like much of a difference, but if you try to use the wrong one, you'll know it at once. Be sure you use the dihedral braces as a guide when you set the top fuselage gussets in place so that the wing will be seated properly. You'll also have to make some decisions when you build the nose of the fuselage, depending on the power source that you select. Spirit of Yesterday provides a firewall for a Texaco engine and one that will fit a direct-drive Speed 400 motor. I used a geared motor and had to build my own mount, but there is plenty of room to work in, and it was easily accomplished.
