Ultimate Endeavor Project

In progress at the same time is a PML Ultimate Endeavor.  The airframes have been fiberglassed and I'll be making several modifications to the stock kit.  It is a 6" diameter rocket and will have a cluster of a 54mm central motor and 3 38mm motors around it.  It will use the same electronics sled for it's avionics bay as the Tomahawk Project and will also be designed to allow for air-starting some of the motors. 

The pieces parts and to give the sense of scale my Small Endeavor next to the Ultimate Endeavor dry fitted (ceiling is too low for the nose cone to go on).

Motor retention for the cluster.

Assembling the motor mount.

One BIG avionics bay!  Note that the tube behind it is a 54mm MMT.
