Sorry about the title, that is not the way I wrote it.....


I just started flying Helicopters in P3D, but I flew RC Helicopters for years and even have a bit of time in an R22, as well as a fixed wing PPL., so I am pretty familiar with the basics. I just got the Milviz 407, and the problem I am having with it is the pitch trim. It is supposed to have forced trim that can be actuated by either pressing a red button on the cyclic or setting up a joystick button on my controller. I have done both, and pushing the button seems to produce no effect at all. The 407 flies nice and level when going from hover to maybe 25 knots, and then starts pitching up requiring forward cyclic to get any kind of speed going. Up around 60-80 , it requires a great deal of forward pressure, like one would experience with a very tail heavy fixed wing, or one that had a severe pitch trim malfunction.

The other way the 407 pitch can be adjusted is using the mouse in the VC and there is a hat switch on top of each cyclic, and by turning the mouse wheel while it is over the hat switch, I can get the cyclic to move by adjusting the trim manually, but as soon as I touch the cyclic, that adjustment goes away and I am back to pitching up again.

Now my question is, is this just the nature of this helicopter, because frankly, unless I want to fly maybe 30 knots at most, it is OK, but for any fast flying, it is a real chore to keep if from climbing. I was also looking at the flysimware Bell 47 G, and wondering if that might be an easier machine to trim.

There is an add-on gauge available in the library called helitrim, that will allow you to trim a helicopter like you would a fixed-wing aircraft. How "realistic" that is, I can't say, but I personally use it on almost every helicopter I have (admittedly, all freeware).
It even has a ini type file you can put in the individual helicopter's folder that allows you to adjust how the trim is effected. How much change each button press for any given axis changes that axis' trim. Very nice for customizing the gauge to a particular helicopter.
Does this help at all?

Will that work in P3D?

I believe so.
It's just a small .xml file, and a .dll. As far as I know, as long as they're both in the right places, it SHOULD work in P3D.
I've been wrong in the past though, many times. All you can do is give it a try, I guess. The instructions in the Readme are pretty complete.
Having said all that, all I have is FSX:SE to draw on, so take it all for what it's worth :D

I gave it a try. It worked sporadically. Sometimes normal trim adjustment and other times from a climb to a dive bomb with one click of trim. I am suspecting this is a P3D issue. Just have to get used to pushing on the cyclic when cruising...

A real 407 doesent have trim and actually climbs like a bat out of #### lol..they even have to put a limit of 2000 ft/min.  While the flight model can't be modeled perfect in flight sim or P3D it requires a decent amount of forward pressure on cyclic.  But with real hydraulics it's not really pressure as much as just a position your forearm rests on your knee.

The Astar is the same way.

They didn't put a force trim in the 407? The 58D has one. I figured they would too.
