Hi Jean-Pierre Thanks for your feedback! Yes, I saw your F-BBBE livery and the dynamic checklist. They are great (I haven't used the checklist, will try it later on). Your English is very fine! for sure better than my French! I am a developer but first I am X-Plane and flightsim user. So thank you very much for your creations!

Hi! I completed the regular flight at FSEconomy. Flight plan here. The distance is 316 nm. Fuel flow -- was 202 gals. ETE -- 2:32. Exactly the same flight on the DC-3 of the X-Aviation on this route has been executed within the specified time and fuel flow was 320 gals. At X-Plane 10.51 the X-Aviation DC-3 is a flying brick. With 1750 rpm/25 inches could drop only. The dynamics are beautiful. The fuel flow on a cruise within the limits stated in the documentation. Now the question is: will the speed indicator show the speed in knots or miles per hour? If at the knots, it is unclear how I managed to disperse the aircraft in a horizontal flight from 1750 rpm/25 inches to 175 knots. If in miles per hour, then how does it take off at 80 miles per hour. Further, the mouse can not turn on the gyro pilot. It switched on to include only the button of the joystick. Inaccurately tuned in the model cowl flaps valves control. Because of this, the temperatures of the cylinders are different. 176/5000. Please check the range of elevator trim and flap release angle indicator scale. These controls are set up on the joystick axis and don't work correctly.

Please check the range of elevator trim and flap release angle indicator scale. These controls are set up on the joystick axis and don't work correctly. Hi ok... Speed indicator is Miles per hour. Here is a quote from the 'Pilot Training Manual for the C-47 - AAF' (other than my real life experience with the C-47, This manual was one of the references to create the VSKYLABS DC-3/C-47 Flying Lab Project): "Stalling speed: 67 mph TAS" (flaps dependable). "...In a normally loaded airplane the tail usually comes up by itself. You can assist tail lift by a slight forward pressure on the control column. When the airplane has attained flying speed (85 to 90 mph under normal load conditions), you can break ground." * on Short-field Takeoff, "...an ease you plane off the ground as soon as you attain minimum flying speed. End of quotes. You'll find the takeoff info on page 46 in that manual, and the stalling speed in page 11. Other useful information can be found also. The Flight dynamics model is ~90% covered, there are issues that will have to be addressed in the long-term development plan, but it is almost "nuance". I will have a second look to the cowl flaps control valve settings and trim/scales. Thanks! The flight model handling characteristics has to be faithful to the real world aircraft, but also enjoyable and comfortable when flying in a simulator in front of a screen, and with a Joystick. I'm glad that you're find the dynamics comfortable and predictable. Appreciate every feedback ! Thanks again

Auto feather? Hi again, I shut down an engine in level flight and followed the emergency checklist. When I push the feathering button, it dosent seem to move in and the prop does not feather but keeps windmilling at a few hundred RPM. The throttle is already brought back,the prop selector to full coarse, mixture idle Cut-off and ignition off Any suggestions, Regards, Andre.

I've read your report and went to another flight. Started cold and dark and also both engines are running. The prop feathering is working as it should be. Which version do you use? (v10.51 or v11)?

Hi, using X-Plane 10.51 with 10.51 DC-3 C47 version 1.1
Thanks for your attention, Andre.

Hi, using X-Plane 10.51 with 10.51 DC-3 C47 version 1.1 Thanks for your attention, Andre. Hi! Just checked it again in both V11 and V10.51. Working fine (cold and dark, engines running....). So...when an engine is turned off (mixture cut off, magnetos off, props to coarse), it is windmilling, but as airspeed goes below ~90 mph, the propeller will stop windmilling and will rotate slowly or will not rotate at all, while it is unfeathered. Then, a push at the feather button will get the button to get inside (animation), and the propeller to be feathered. I've tested it several times after your feedback. Are you using any hardware with autofeather switches? I will dive deeper to see how can I help you. Will get back to you soon!

Need a rivet map on the plane. Then I can make an excellent texture. That's what's coming out now.

Good morning, as per your query, my sim host CH Yoke, Rudder pedals, and Throttle Quadrant, GF TQ6 for prop control, Saitek flight switch panel and an MCP-PRO. None of the switches on these panels are attributed to prop feathering switch. Feathering either prop in flight turned out negative, On the other hand, going into Plane Maker and checking the box labelled (all prop feather when prop control at minimum) the prop did feather but the feathering button did not move. when I tried to unfeather either by moving the prop lever out of full coarse or using the feathering button the prop did not start spinning on its own as it would on the real aircraft.
I notice the MATOW at 31,000 pds. is that the military weight ? It seems like a lot, compared to the 26,200 I was used to.
Thank for your time, Andre.

Hi Ok...next thing to check is: Try to do the procedure using only the mouse manipulator (click and drag). ...we need to check if you are having a hardware setting conflict which is preventing your mouse manipulator to execute a complete fuel cut off when you drag the mixture to cut off. Weight is military, that is right, but one can set any desired max weight a specific mission or purpose. Awaiting you answer regarding the feathering. Don't forget to set it all back in plane maker to the default of v001.1

Hello again, It finally worked. What I did was to designate a switch on the CHTQ to command the mixture. As it was with the mouse, I could not completely close the mixture control where as with the quadrant switch I could bring the Fuel Flow to zero (setting, engine, FF)...According to the manual : engine loss at 31,000, the live engine will take you to the scene of the accident !!! Kepp the blue side up, Andre.

The DC-3/C-47 has always been one of my favourite aircraft, and it is great to see the wonderful model being "built" here.
I was fortunate enough to be given a guided tour of an ARDU C-47 at RAAF Base Edinburgh not long before they were retired from service.
Really looking forward to the on-going development.
Malcolm

Hello Old Birds lovers, Even though I tried to find rigging figures for the DC-3 flight control, I drew a blank. However 4 degrees of downward movement for the elevators sounds like an awful small number, can you confirm ?
Gooney.
