Guillow's Sky Streak Takeoff From Ground

I made some changes to this Guillow's Sky Streak to enable it to take off from the ground.  The airplane parts came from the single packs and the wheels came from a Guillow's Air Plane Design Studio. The modifications consisted of extending the wing slot in the fuselage 3/8" forward, wet forming the wing to add a cambered airfoil and increase the dihedral angle from 6 degrees to 12 degrees (1.3" under each wingtip) and reshaping the motor hook to provide more clearance between the motor and the stick.  I lubricated the blue kit motor with the classic mix of green soap and glycerin and hand wound 400 turns into it.  Moving the wing forward is necessary to accommodate the more forward center of gravity from the added weight of the wheels.  The camber gives the wings more lift for the added weight.  The added dihedral gives the plane better roll stability, so it doesn't roll the left wing into the ground and drag it along.  The technique of wet forming is described on EndlessLift.
