Hi all
Thanks for the update V1.3
However I have noticed a considerable increase in fuel usage in 1.3
Pre 1.3 I could get the fuel usage easy to 6 Gal per hours
Post 1.3 I can hardly get it below 10 Gal / hour 
measured by the inbuilt Flight computer

Thanks in advance if you can help
Bob

Confirming this is true for me as well. Full power after v3 uses up to 17 GPM at sea level.
I 'fixed' this manually by tweaking the aircraft.cfg piston engine settings as follows:

[piston_engine]
bestpowerspecificfuelconsumption = 0.70 //1.0

Fuel consumption at that setting is more like realistic 10GPM at full power, 9-8 gpm at 85% power, and 7 GPM at 75% power.

Cheers.

Thanks for the feedback. We've updated the product and demo installers to address the fuel usage issue.
