Ever since flying the DA-42 I felt it was underpowered. Indeed, Alabeo modelled the engines on the Thielert 1.7 Litre units at the start of the DA-42's production run in 2004.

Real world it didn't take long for feedback to get to Diamond that the engines were piss poor. Then Thielert went out of business and Diamond tried Lycoming for a bit before finally settling on Austro Turbo 300's which the current DA-42 IV are equipped with. Much faster and leaner burning and make this bird a joy to fly.

I tweaked the aircraft.cfg as I flew around the World. It essentially "upgrades" the engines from the Alabeo modelled Thielert 1.7 Litre (under-powered) to the current Austro Turbo 300. It ups the power quite a lot - you can achieve level flight a few knots down from Vne.

I tweaked the cruise scalars and thrust and drag to represent the aerodynamic cleanup of cowlings and flush rivet heads that Diamond did for the IV together with the new propeller design done in 2012.

Bear in mind that with just you in the cockpit (solo) you won't need full power on TO - as in real Twin Star IV. You and three passengers and a load of luggage - full power.

Power should be applied on gaining altitude to give you realisitic KIAS's/ fuel consumption at cruise heights with power set between 70 - 84 %. Read the notes for the real thing.

PM me for a link to the Drop Box file.

Obviously don't forget to backup your original aircraft.cfg (rename it something like aircraftBACKUP.cfg and substitute this one.)

And the usual: Use at your own risk. Although it works well for me on my own system I take no responsibility for your use of this file, any damage caused or financial loss.

Enjoy,
