I look forward to trying the Tiger Moth in FS2004, although I really
haven't taken to FS2004 yet - not least because VFR scenery doesn't seem
as crisp as in FS2002, and also my problem with pan view.
It's only taken two years but I have finally updated the FS2002 Tiger Moth collection to work properly in FS2004.
The major problem was with the aerodynamics as MS had changed a lot of parameters in FS2004 (as they have again in FSX). This meant that although the aircraft would fly in FS2004 it flew very badly - and developed annoying traits like rapid pitch up from Slew and reversed pitch change with power changes. Although I tried to cure these early on it was apparent that I was guessing and the cure was buried deep in the graphs in the .air file.
All is now cured, thanks to a very detailed description of the alterations needed to the table files in the .air file. It was a horrible 12 point conversion, one involving messy mathematical calculations applied to every single point in the 404 graph. The rest weren't exactly easy either.
I also took the opportunity to revise a few other handling values and so you will notice slightly different behaviour. Users without rudder pedals are in for a shock if they try steep turns and I'd recommend turning auto rudder on. Users with pedals had better start using their feet more!
One additional touch - although it is rather "botchy". The Tiger has always annoyed me in that its tailskid has never worked as in real life. A skid is far more draggy than a tailwheel - which is why you don't need brakes. Put a tailwheel on the aircraft and ground resistance vanishes, which is why the Canadian Tiger was fitted with brakes. The aircraft.cfg file has a setting for a tailskid but it seems to impart no additional drag on the ground - all it seems to do is kick up a bit more dust.
What I have done is map the brakes to the tailskid. If landing on a tarmac runway where the skid has almost zero drag you leave the brakes off. If you are landing on grass put the parking brake on. As soon as the skid touches the ground the resistance will slow the aircraft down rather nicely - as close as I could get to the real thing. Take the brakes off for taxying though as you won't move with them on. You may also find the Tiger turns a bit better on the ground too as I altered the ground handling.
In addition to the above I have completely rebuilt the panel with all new XML gauges that are true to the original Tiger fit. Some of the gauges also have alternative displays - single and dual needle altimeters, same for the tachometer and an ASI in both knots and MPH. Clicking on each side of the dial will swap the instrument over.
At the moment the update doesn't include the floatplane variant as I am still working on the dynamics for this.
I'd welcome anyone testing the new aircraft in case I have overlooked anything in the zip or with the aircraft itself. You can grab it from:
One word of caution though. FS doesn't like duplicate aircraft titles so you will have to delete your original DH82_Tiger_Moth folder (but not the separate floatplane model). You can do this after installing the new files because these will install into a new folder called DH82A_Tiger_Moth.
If any of you have additional repaints for the aircraft you can drag the texture folders for these over to the new Tiger folder. Don't forget to cut and paste the appropriate sections of the aircraft.cfg file over too.
