We are working several separate designs, but with parts that could be interchanged.

Primary Design

Here is a design for a 3inch cargo unit on a 2.14inch (BT70) booster. It is designed to be about 500g and use an F24 or F39 motor.

Here are some of the drawings that got us to this design.

Secondary Design

This a a simple design using a 3inch booster and cargo unit.  It is designed to be light weight (about 400g) and use a E18 or E28 motor.
