Re: digital protractor

[Graham Clarke <gemin@cix.compulink.co.uk>]

Anyone who has bought the standard Warp Drive prop. will know that it 
comes with a most excellent protractor/spirit level for setting the prop. 
pitch to a fraction of a degree. If I had known this before, I would not 
have bothered making the plumb-bob device, and would not think a digital 
device would be cost effective by comparison. Someone should ask if it 
can be bought separately
