May 22, 2003: Today we had a rudder cable fail in flight (no damage to the airplane; it landed without incident). The failure was due to the knot slipping through the fitting so the problem could be attributed to improper installation, but both Erik and I feel that the Kevlar system is probably better suited to a smaller, lighter aircraft.

Erik is changing his pull pull system to a standard steel cable system such as the ones sold by Nelson Specialties. The prototype plane has had steel cables from the beginning. If your large scale airplane is flying with the Kevlar lines and fittings we recommend that you change to the steel cables.

February 25, 2003: On the plan, the stabilizer tube socket diameter is shown as 0.765 but the stabilizer socket supplied by TNT and the hole cut in the foam supplied by FlyingFoam.com measures somewhere in between 0.670 and 0.690. To be safe, it is best to cut the hole somewhat smaller using the centering marks on the plan and gradually sand it to fit your exact stabilizer tube socket. If you've already cut the hole too large it's no problem. Make an 1/8-inch light-ply backing plate that fits the stabilizer tube socket and glue it in place inside the fuselage along with the stabilizer tube once you've aligned the stabilizers. Fill the gap on the outside with an epoxy and micro-balloon paste and once dry sand it all flush to the fuselage sides. 

February 3, 2003: If you plan to cut your own foam, The main wings should have dihedral created by the taper of the wing. In other words the top of the wing will be straight across the top horizontal to the ground and parallel to the wing tube and the bottom of the wing will taper up to create the dihedral. The stabs have no dihedral, the centerline of the stab is centered on the tube.

December 26, 2002: On the plan, the motorbox sides are listed as 1/8-inch light ply, they should be 1/8-inch aircraft ply.

December 12, 2002: When cutting the fuse sides, the very aft bay directly under the stab was intended to be optional. Do not cut the opening out until you have determined if you are going to use a pull-pull rudder system. If you decide to cut the bay out, be sure to leave ample room for the stabilizer mounting tab per the plans.
