There are no specialist boards on this forum which cover the rather exotic machinery you have. However if you joint "the other lot" **LINK** you'll find several such boards under "Dry Dock: Shipyard; Builds and questions", and I know there are some seriously committed folk who contribute to it. You will have to make your own judgement on the replies; some folk on that forum are more prone to voicing an opinion than giving facts!
BTW it would help if you use capitals for AMPS – it helps to avoid questions about the current involved… I think it was Agnew Model Propulsion Systems, but I'm probably wrong.
