Another issue is that, on landing with the dc3-yasim at a rather
high speed (so that the angle of attack is near 0), the tail
instantly falls onto the runway, but the aircraft nevertheless
doesn't take off again, although the angle of attack just increased
rapidly. Although I haven't

What I think you're seeing is the feature that *everyone* who tries
the DC-3 discovers: the DC-3 is a taildragger, and is really, really,
really (!) hard to handle on the ground. I've had zillions of
complaints about this, and have investigated every one thoroughly.

I don't know whether YASim models ground effect; if it does, the
tailplane becomes more effective in ground effect and sucks the tail
downwards. That'll exacerbate the torque of the forward gear mounting
position.
Oooh! Good point. YASim does indeed model ground effect

I have not been able to do so for a long time -- it always ends up
spinning like a top. If you can do it, perhaps it would help if you
posted a step-by-step.

Here's a lot of information on taxiing the DC-3:

The most important point is that the DC-3 tailwheel must be locked for
takeoff and landing (i.e. it doesn't caster freely). Also of note:
1. According to the author, at least, differential braking

while taxiing the DC-3; you should use differential power instead
except for very tight turns.
I'll buy that. But working dual throttles during the takeoff and
landing rolls can't possibly be
Andy,
CAUTION: THE TAIL WHEEL LOCK MUST BE LOCKED DURING TAKE OFF AND
LANDING.
Sounds like good advice to me. I'm not at home right now; can someone
remove the castering setting from the dc3.xml file and try it? If
this is the solution, then I'll add a property-based control for

Andy,
I just made two recordings of flights with the DC3, but can't play
them back because fgfs segfaults. I can put them on the web if that
helps (maybe even to debug the segfault...).

You started up the engines, firewalled the throttle, let the RPMs

That's clearly unphysical.
Why ? The nose pitches down with power and brake application.
So, releasing the brakes makes the nose pitch up.

AVSim.com had a post today with a really good link to an aircraft
resource page. It's here:
http://www.aircraftresourcecenter.com/walk.htm
That page has walk-around pics for many military aircraft from a host of
countries. Great stuff for anyone working on 3D models or panels.
