A few days ago, Solomoriah described his little "Two-Bitz" style model, and I said I'd try to run a RockSim of it. Well, I managed to approximate the design with a cylindrical form, and free-form-tweaked a set of fins based around the photo he had of the prototype. The performance is outstanding, as long as the model actually holds up to the stress!
I'm (re)naming this creation TUPPENCE, as a take-off of TWO-BITZ. Hope you don't mind, Solo...
(I know, you call it SLIDEWHISTLE, and that's the official name; I was trying to think of something that was similar to Two-Bitz...
Length: ~2.88" (This is an estimate, based on my free-form fins...)
Diameter: ~0.64" (2" divided by 3.1416...)
Fin Span: ~4.28" (Based on my free-form fins...)
Weight: ~0.064 oz

The plans show a simulated streamer, which is not actually there but is required to obtain the flight profile. The motor should freely blow out at deployment. This is obviously a sacrificial Mosquito-esque model, which one fully expects to loose but doesn't have to feel badly about. One additional observation -- the model is NOT STABLE until the motor is inserted.
