The original TEOSAWKI was designed by Clayton Smith around 2005 with a 53″ span. It was reported that Clayton, an avid combat flyer, had a dislike of the fancy, super finished, complicated stunt models; so he set out to create a rugged, simple to build, model capable of a 500+ flight score without appearance points. The name TEOSAWKI is actually an acronym for The End Of Stunt As We Know It.

When it was announced that 1/2A Stunt was to be flown at the 23rd Brodak Fly-in, the TEOSAWKI was recommended by Will Davis as a candidate. BMJR built a series of 3 prototypes before finalizing the design. The BMJR TEOSAWKI has a 31″ span with 208 sq. in of area; and a final flying weight of 8 1/4 oz. It is defiantly capable of the entire AMA pattern on 50ft lines.

I have an original TEOSAWKI model that was built for me by the designer, Clayton Smith. The End Of Stunt As We Know It is a great flying plane, and has won many contests when flown by good pilots.
The 1/2A size TEOSAWKI kit from BMJR is a very nice way to build this plane on a smaller scale. I made some adjustments when building mine.

1. The gear mounting was changed so that the straps could lay flat over the gear wires, and a screw and washer were added on top of the fuselage to hold down the landing gear wire.

2. The AP Wasp .061 engine has throttle control, so a linkage was added that allows throttle adjustment, then it is locked with a washer and screw.

3. A screw eye was added aft under the fuselage, to enable use of a stooge.

4. A KAP-PAK B22 fuel tank was modified for uniflow operation, and with fuel pickup from the bottom.

5. The fuel tank is held down by rubber bands over formed keepers. After finishing, a length of double-stick tape was positioned under the fuel tank to keep it firmly in place.
