It is most assuredly not disingenuous to question the legality of purchased vp hubs for F1D and other indoor classes that have a BOM rule. The argument that using a purchased hub is no different from using rare, light condensor paper for A6, 5/99 rubber for the motor, or light balsa with good stiffness is like comparing a wedding cake to flour. A vp hub is made from various parts and materials. The Treger hub is made from materials you can buy from many places in the USA. The key word is that the vp hub is made or fabricated from basic materials and assembled from many separate parts. Buying basic materials and buying a ready-made vp hub are in no way the same thing. And, neither the FAI nor the AMA require all of the tools one uses for construction or flying to be made by the flier. Only the plane itself must be constructed by the flier.

Finally, here is a bit of interesting information. The indoor flier who holds more world championships that any other person constructs his current F1D's using a great deal of balsa and material from local hobby shops and other local sources. For the most part, only the Tan II rubber, the light covering film (Y2K2), the boron fibers, and the thin c-grain balsa for the fuselage (motor stick, extension, and tail boom) are purchased from specialized indoor suppliers. The boron fibers and balsa are available for purchase at this time. A slightly heavier film (OS film) is readily available, too. And, the newest Tan SS rubber is fast becoming good enough to compete with the older and more fragile Tan II rubber.

Just back from flying my F1D over lunch time and in a good mood,

Leo
