Europa-List: Constant Speed newbie question

[steve v <s.vestuti@virgin.net>]

Hi,
While waiting for my constant speed to arrive, i have been 
looking at the manifold preassure gauges and found that 
they are available withe different scales - 35" or 50" FSD, 
cannont find any reference anywhere on manufactures blurb 
or the rotax installation manual as to which is needed, 
i've got the run of the mill standard 912S, can anyone 
shed any light?
