FlightGear - Flight Simulator FGAddon

DHC6: Small fix for engines and engine instruments:
- Idle Propeller RPM is somewhere around 23%, hence I reduced fine-stop to 0.2. (see http://www.blm.gov/style/medialib/blm/nifc/av.Par.70826.File.tmp/SOPA_otter.pdf, page 12)
- Idle Gas Generator RPM is aprox. 50-52%. (see http://www.cram.com/flashcards/twin-otter-dhc6-300-1980260)
- This aircraft has only "Condition OFF" or "Condition ON". So now the condition levers con occupy only the "on" and the "off" position.
- Animate the small indicators on Propeller RPM and GG RPM.

mosquito: make the fuel cocks visible in the bomber variant.
* Models/mosquito.ac: move the back of the navigator seat aft so that

bay doors.
