Is it overpowered?

TRying my new PA46T out. I have noticed that when I take off with throttles to full and then pitch up to rotate that it really becomes very difficult to control the pitch of the aircraft.

 

During the takeoff it starts pitching up to nearly 20 degrees even though I am pushing the yoke down to try to reduce the pitch. It is like it wants to go straight up to the skies.

Is it necessary to have full throttle and not 90% N1?

Perhaps not but it is really nearly impossible to read out those gauges unless you zoom in, and if you do zoom in then you probably do something wrong during this crucial stage of flight.

 

I really don't know why Carenado didn't add the 2D versions of those gauges just like they did for the Piper Seneca II. It really helps out a lot.

Reckon it isnt an issue of overpowered then. more of a cant read the gauges.

From what I've read about the real aircraft, it's pretty accurate. The real aircraft does climb at a very steep angle.

Also don't take off with the throttle to full, you'll overtorque the engine.

As others have mentioned, you don't firewall the throttle for takeoff in a turbine like this.  Sorry, I haven't flown mine in a while so I can't give you the specific numbers off the top of my head, but you don't want to advance past a given torque value and firewalling will definitely do that.  Bring the throttle up gradually allowing the turbine to spool up so torque doesn't suddenly get away from you.  There's a fair bit of lag as it spools up, so anticipate that.  I find the digital readouts perfectly reasonable to monitor, and doing so is very much a part of the real-world workload you'd have if you were flying the real thing.

 

That said, this plane does like to go nose-up after rotation.  Knowing this, I generally compromise on takeoff trim setting a bit, requiring a bit firmer tug to rotate and even then, I'm ready to add some additional nose-down trim after rotation.  Sounds harder than it is once you get the hang of it.  As in a RW plane of this kind, trim is your friend.

 

And yes, IRL this turbine conversion does have power that can easily exceed the airframe's limitations down low (which is why it's a plane in which you plan to get high, fast) and it does require a pilot keeping things within limits.  That's part of what makes this fun to fly.

 

Good luck.

Thanks TTLOCS, I think I am getting the hang of it already for more controlled take offs.
