I am trying to calculate the CG for my Mk II aircraft with some non-standard
components in the engine bay, and need a starting point for the standard
fit.  Does anyone have an accurate weight for the Lycoming 320 or 360 engine
with all of the attachments (alternator, starter, mags etc)?  Similarly do
you have the weight of the "standard" constant speed prop, e.g. the Hartzell
2 or 3 blade unit?  It will make the calculations a lot easier,not to say
more accurate.  Thanks.
