Your videos, Tim, show excellent take off and landing behaviour, though I don't see longer cruise periods. In my first tests the maximum and economy cruise behaviour of 300 or 300+ don't seem to be much different, I need more torque in the 300+ to maintain the same IAS (150 KIAS at 6000 ft), haven't looked at fuel consumption yet.
I haven't found cruise performance information for the DHC-6-400 (same engines as your 300+) compared to the DHC-6-300.
Is the power surplus for the 300+ meant to be for shorter take off and steeper climb, or should it be for faster cruise, too?
There is another issue that strikes me, quite similar to the Piper Aerostar (YASIM, too), and which is rather unfitting for VA use: changes in AP altitude or pitch setting are executed very abruptly, not as smooth, as one would wish for one's passengers. I also observed it in your videos. Is there anything to be done about it?

The behavior should be about the same. The engines spool down faster in the 300+, giving it a bit more realism when landing.
Also landing lights work, intake deflectors work. Radar altimeter has a voice alert.
The power surplus is for high altitude work. I cruise the Caribbean, and have yet to use full throttle. If you want to frequent airports like Lukla, the extra power will help.
Actually, the DHC-6-300+ AP transition is not quite as bad as the 300. I did dampen it out a little. It works best if you can get the a/c in level flight or near a zero rate of climb before engaging the AP.
Edit: I have some full flights that I streamed that show the 300+ in level flight and transitions. See the link to my YouTube page I posted above.
I highly recommend a yoke/joystick with throttle and pedals. I have a Saitek/Logitech yoke (fully moded with Bodnar fix. No deadzone. No detents), throttle quadrant, and pedals.
