Sorry if this is obvious, but want to make sure all the bases are covered. Underneath where you set primary and secondary, there's a toggle which selects between PMS50 and TDS. Do you have this set to PMS50? Scott

Fuel flow should be 133 PPH per Engine which should net you 241 KTAS in the Grand Duke, and 225 KTAS in the stock Duke. Same settings lower will give you 217 KTAS in the Grand at 10,000 feet and 198 KTAS at sea level again in the Grand. Climb to FL 240, and increase the throttle to 34.1 in MP with the same 2750 RPM for the same fuel flow of 133 PPH per engine but at 250 KTAS in the Grand or 234 in the stock Duke. Keep in mind that these figures are for an ISA standard day. It's a bit less straightforward/linear when colder or warmer. You can find more detail in a RW POH - several are available on line. And again, I've not found one specific to the Grand Duke. If anyone knows of a source, I'd appreciate a link. While at most altitudes the differences are fairly minor and can be ignored in the sim if you don't enjoy sweating the details, the biggest limiter which can't be ignored is on a warmer than standard day, which is why I mentioned flying lower during summer months. The higher density altitudes of summer will also impact whether the pressurization system can handle keeping the cabin altitude below 10,000' in the low flight levels without exceeding pressure limits.

It was an unpacking issue with the zip.
