RE: TOM BRETT'S DESIGNS-UPDATE
I know this is somewhat of a stretch, but do you think that Tom was using some ideas from the XB-70 Valkyrie? The aircraft had a delta wing and hinged wing tips that could be folded down to a 65 degree angle to improve stability of the aircraft at supersonic speeds. Now I know that our models don't fly anywhere near those speeds, but perhaps Tom thought the same principals would apply.
