The key word being MAX. My .015 shaft will be no where near the Max of
1/32”.

Carl

The 1/32” max prop shaft diameter has been universally ignored for years.

 

For the current “A-6 Committee” rules look in the files section of
Indoor_Construction.

Guys,

Ren makes a good point: I'd vote but I don't even know what the present
rules are or where to find them.


Van Dover published these in the Brainbuster Newsletter for the 2010 A-6 and
Ministick Postal Contest.

A-6 Model Rules:
1. 30 sq inch max wing area
2. 1/32" max prop shaft diameter.
3. 6 inch max prop diameter. The blades are to be flat, no camber. Blades
may be balsa or unlightened plastic. No foam. 1/32" thick or 1 mm.
4. 6 inch max motor stick length as measured from prop thrust bearing to
rear hook. Tail boom length unlimited.
5. All strip wood construction to be a minimum of 1/16" x 1/16" square, or
1.5 x 1.5 mm where only metric sizes available. The strip wood may not be
sanded to any shape other than a square.
6. All sheet wood construction, prop blades, wing and stab ribs are to be a
minimum of 1/32" or 1 mm thick. Prop blade edges will not be rounded.
7. All wing and stab ribs will be 1/32" x 1/16" or 1.5 x 1.0 mm cross
section.
8. Covering materials are limited to Jap tissue, Condenser or Gampi paper.
9. Only wood, wire, adhesives and allowed covering materials can be used
for construction, with the exception of the prop shaft support and bearing,
which may be wire, aluminum, or plastic. No special indoor materials may be
used.
10. Rubber power only.
11. The use of metric size wood is restricted to those who normally cannot
get other size wood.
12. The model must weigh a minimum of 1.2 grams.

I am planning on sticking to this for USIC 2010.
