Over the past weekend I have completed a pretty sold test stand for running the 12 engines.

It is machined from 300x100x20 slab of aluminium. There is provision for both Super Silencer mounting and tuned pipes (test stand can also be used for F2A tests). 

The stand will be bolted down to a Workmate with 4 off 6mm cap heads.

A good test stand is the starting point for repeatable engine testing.
