This plane SHOULD climb at 4000fpm EASILY up to 15k and 2000 easy after until mid 20s then 1000 easy until cruise. WITHOUT damaging the engine. It should do this without maxing out controls comfortably. 

Something is wrong.. 

Here's hoping it was a random Su15 bug or something. Can't use the plane in this state. 

Guessing at a random bug, fine for me since SU15. Last flight was out of LSZA, climbed so fast it lit the cabin differential up...

... so unless it doesn't like starting at altitude?

 I didn't realize you are referring to Turbine version. Turbine version doesn't have prop sync. Because turbine is actual conversion from Piston, circuit breaker still remains.

Interesting.  Pretty certain the Realair TDv2 had a prop sync switch

I think that may have been a mistake.  I was reading up on prop synchrophasers - as I understand the turboprop engines automatically adjust the prop angle to match via some internal computer somewhere.

It's possible the turbine duke doesn't have this though - I'm not really sure.

As I went through my study time of the Blacksquare yestereday I was referring to my self-edited RA TDv2 checklist I scared up in my Jep binder.  I noted the prop sync was a line item.  Looked all over in the Blacksquare manual (I only purchased the Turbine Duke from BS) and only found the circuit breaker reference.  That started the "chase".  Thanks as always fellow Avsim members.  Lot of value here!

Someone asked the same question on Just Flight. Response was:

"Good question! The real-world FAA approved STC (supplemental type certificate) flight manual for the Turbine Duke does not list a prop sync switch anywhere in the cockpit; however, there is a 2 amp circuit breaker labeled, "Prop Sync" (in the real aircraft)."

Just gave it a try from LSZS to compare, no issues at all with takeoff - initial climb out at 3000fpm, then 2000fpm at 140kts until about 17000ft then nosed down a bit and got 1000fpm+ at 150kts all the way to 27000 .. ..

I flew different area last night and power was fine again reversers didn't work on landing guess I have to configure beta again after update? Weird. AP has trouble intercepting NAV at moment. I'm zig zagging unless I use HDG to get on track first.
