Build Information:
This build will create a dual deploy single compartment modification of the Polecat instructions. This will allow this V-2, which has a 75mm motor mount, to go to high altitudes without worrying about single deploy drifting. This will be accomplished with a Rattworks A.R.R.D (which will be shown an described in more detail below).

Built up fin can (without any fillets or fiberglassing):

Internal fiberglassing to secure tailcone to plywood fins:

Fin can tailcone was filled with expanding foam to add rigidity and durability.

Public Missiles expanding foam used for tailcone:

Rocket will start deviating from instructions to facilitate dual deploy. Tailcone coupling sections will be trimmed back to the blue tape to allow more usable space in the body tube. The 7-ply centering ring is replaced with a thicker 9-ply centering ring:

The decision was made to abandon the A.R.R.D. for a more conventional dual deply though this has to fit into one body compartment and the following diagrams show the anticipated plan.
