Smoothie question

The origional Smoothie came with built up tail surfaces.
If one were to use solid sheet, rather than built up tail surfaces, would that disqualify it for OTS?

Peter, I don't know the answer to your question, but I have one regarding the Smoothie as well, and hopefully posting it here will expand rather than dilute your question. I just got a new Brodak Smoothie kit. It has OTS Legal all over the box and plans. As I look at the kit, I see some gross differences from the original. The most important being the airfoil. The kit has a pretty fat blunt nosed airfoil. The original had a fairly slim airfoil profile and a pretty pointed leading edge. I have the original plans and an old Dumas (? VECO? I don't remember just now) kit plus the original magazine article. I read in the magazine article Bob Palmer said the airfoil was responsible for it's excellent windy weather performance. The canopy and turtle deck are also different.

So the question is, how can it be considered OTS Legal. I know that later versions of the Ringmaster are disallowed, due to the airfoil I've been told.

Just curious.

This is a sad one. The Bob Palmer original Smoothie was not the one origionally made for sale to the public! Bob and John Brodak collaborated to bring us the real version as Bob knew it and has attested to the authentisity of Brodak's rendition. Therefore all is legal with John's kit for OTS.

The OTS rules state you can do modifications to the internal structure so long as you do not change the original external shapes, ie; airfoils. The tank area can be modified to hold larger tanks for instance. If you maintain the original shape, size and airfoil of the "original" (not Veco version) stabilizer, then it should be OTS legal. Any GSCBers out there?

You can use solid surfaces if you want to, as long as size, shape etc is the same. But why? Built up tends to be lighter, and
the plane had a design weight of around 32oz, can I build that light, nope, but I had one that ended up at 36oz, with a Veco .31
flew well.
