============
1. Added support for P3Dv4.1

I couldn't be more pleased that this wonderful aircraft finally made it to P3D 4.1. It looks absolutely great and is such a pleasure to have in the hanger.

Sadly it will stay in the hanger for the foreseeable future, as the prop pitch control now makes the aircraft completely unusable. This was a slight issue in FSX as I recall, but now just touching the prop levers causes the engine speed to wobble, the airframe itself to yaw and twist as the governors take control and finally settle on a figure that may or may not relate to where you set the levers. You then have to go through the rigmarole over and over until you finally get the prop speed you are after.

Let's work out what's going on.
Are you seeing this in FSX?
What is your hardware/software/addons setup?

I don't have fsx any more so someone else will have to chime in here. I'm on p3dv4.1 with a ch throttle quadrant. Everything goes via fsuipc and works great with your cessna 410.

Anything on this? Is there anything you need from me?

I have alerted the team and await their response.

OK great thanks. I have waited so long to get this aircraft into P3D4 I am a little impatient, so apologies for that.

Hi - Our devs and testers have investigated and see some initial fluctuation of RPM but could not replicate the yaw and twist. Do you have any more information that can help us diagnose the trouble?

Sure. I can tell you with some certainty that the yaw and twist is because the RPM's are coming down slightly out of sync with each other. This is because I am using two levers to control each engines rpm rather than a single lever to control both. It's impossible to move the two levers in exact synchronisation because they are so sensitive to movement. The yaw and twist in the airframe is as a result of the differential thrust that is being created by each engine as the rpms fluctuate.

There is nothing wrong with the calibration of my device as on every other twin engine aircraft I have (including your C310), the props come down smoothly and reduce rpm in a controllable manner. I am surprised to hear your devs reporting "some" fluctuation. This is not a minor issue, this makes the aircraft un-flyable. This was a problem with the earlier FSX version of this sim as well (as I have previously reported) but it seems to be even worse under p3d4.1.

thank you - i will relay this to the devs

Just for your info I downloaded the latest installer and it does seem a bit 'juddery' when altering the prop and mixture controls. However it is not extreme in my case and can live with it. Trouble is when someone mentions a problem you start looking hard.

I made a quick video to highlight the problem. It's my first screen cap video so excuse the quality, but I decided to learn how to do it to help the devs get this fixed. I love this aircraft and I just want it to be right.

Hi All

I appreciate it's been a busy few weeks, but is there any news on this?

Its been 3 weeks since I made and uploaded the video for you, and 10 days since my reminder. Has this been swept under the carpet?

I have flagged it for the team's attention, but it is not our highest priority at the moment - especially considering that the issue seems to affect only you and Simondix. Sorry.
