Duke Turbine Question

Featured Replies

I was flying it in a test flight today and noticed that it doesn't take much to either go into overspeed with the throttle is that normal?

Yup, that is about it. The bird is overpowered, wonderfully so, and will overspeed easily.Kind regards,

Those are big PT6-21 (or -25s? Which is simulated?) engines on a small cabin class twin. You just have to set the power per the manual.
An engine with a turbo in it is very powerful.
Two things:
  • We're talking about the B60 "Turbine" Duke. Not the turbo-charged recip'.
  • Being turbo charged (turbo normalized) doesn't mean the engine is necessarily "more powerful" than normally aspirated engines, it just maintains full power up to much higher altitudes

Just thought I'd share.

She's running the PT6A-35 at some 550 SHP and if you mean the ability to easily brake the red line on the air speed indicator at low altitudes, you are perfectly right. Now the regime to fly her (somehow economically) would be FL200+ I guess. At least, that's where the engine limits dictate the speed, not the certified IAS limit.On the IAS limit, Zane Gard (he flew the real plane) explained a bit here. http://forum.avsim.n...11#entry1941611I think the whole thread is worth a read to catch the character and philosophy of that bird. At low altitudes, the engine power allows for a very quick climbs, so it's easy to bring her up to those FL200+.He's recommended some 160 KIAS climb speed, which still gives you some 2000 fpm if I'm correct. Climbing too fast (fpm) is a bit of pain for the pressurization, but you can adjust the rate there if you like.

Interesting link, thanks for that. But it's derated on the T Duke. Same for the JetProp by the way, means the derated character.Edited. Here's the rw flyer on that plane. You can get her with the -35 and -21, but they both end up at 550 SHP 'flat'. http://www.royalturb.../specifications I like the 'Noise Level' section of that doc. So true!Here's some more read for the owners. http://www.planeandpilotmag.com/aircraft/pilot-reports/general-pilot-reports/301-knots.htmlBut I'd love to try an imaginary 2x750 SHP model. Must be close to being capable of a vertical takeoff. :(

Amazing numbers come with that mod! Turning a somewhat mediocre cabin class (because of maintenance expenses) into an extreme machine (with equally expensive maintenance).

the aircraft in reality, I believe is overpowered....but thats what makes it so cool :)

Happy Flying!

if you're gonna play, you're gonna pay. And too: Speed costs. How fast do you want to go?? Answer bloody dang fast!!
