[F-FT] Anyone build the Cosmos Mariner yet?

I just cracked open my Estes Cosmos Mariner kit, and have to say I'm actually pretty excited about it. Has anyone built one yet?
The reason I ask is that it seems a bit 'off' in that only the left elevator has elastic on it. Apparently the right elevator is glued in the 'up' position, and the left one is held in the down position during boost. I'm a little worried about what this would do to the boost phase of the flight.
I guess I'll build this one stock and see what happens...

P.S. This is not a quick kit to put together. There are a few places where it's do a step, apply silicon glue, wait overnight -- so this is definitely not a kit for a beginner. On the other hand, the parts all seem to be well made, and it's got laser cut fins, so it won't be too tough -- all in all, could be a really great build.

Discussed on The Rocketry Forum.
Intended to spiral on the way up - and hopefully it actually DOES spiral unlike the "Foam Orbiter of Death" which never really spiraled.
Large delta wings with airfoils will arc over in a big loop or a bunch of loops unless you have something to counteract or neutralize the lift. Either large elevons set way down during boost or one elevon set up and one down during boost to induce a spiral roll.
