I've tried out the recent c150 updates, and have observed the following
problems:

1) the speeds in the help file and on the specially crafted ASI seem
different from what the real Cessnas have. C150 was an inferior version to
a C152, with all the speeds lower, and same size tanks. Here's what a 1985
C152 book says:

108 rated BHP @ 2550 RPM
2x13gal tanks, 24.5 gal usable -- std tanks
2x19.5gal tanks, 37.5 gal usable -- long-range tanks
You are right, for some unknown reason to me I changed the tanks capacity.

max gross ramp weight (taxi) 1675lbs
MGTOW: 1670
MG landing weight: same

wing loading: 10.5 lbs/sq.ft
power loading: 15.5 lbs/hp

Speeds:
        KCAS    KIAS
V_NE    145     149
V_NO    108     111
[EMAIL PROTECTED]:
@1670   101     104
@1500   96      98
@1350   91      93
V_FE    87      85

Hence the ASI markings are: white arc 35-85 Green: 40-111 Yellow: 111-149
and the red line is 149KIAS.

But the ASI markings and the help file gives MPH not knots. To be exact the asi
has primary markings in MPH and a secondary markings in Knots in the middle.

2) whenever I ask to reposition the aircraft,
fgfs sometime freezes with the splashscreen on, and sometimes reports a
crash as follows:

Position for KSFO is (-122.383, 37.621)
 Crash: Attempted to fly under ground.
Playing audio after 500.867 sec: intense ground contact

(this is in response to a 'location on the ground' command, 28R @ KSFO)

Sometimes at the same time I also see the aircraft tumbling backwards and
having its tail going underground, controls held neutral, tailwind never
exceeding 7  knots. Could this be that the model doesn't account for the
pilot's weight?

Yes I should add the pilot's weight, the aircraft is too light and can be blown away by very little
wind. You should disable metar /

3) in the cockpit view, I see strange speckles around the yokes, which
keep moving; you may get the idea by looking at a (still) image at
http://www.tarunz.org/~vassilii/Images/fg/c150-speckles.jpg

I don't know from where this comes. I've just made a check in 800x600 but I can't see that problem here. The texture used by the yoke is also used for the cabin interior, do you
have the problem only for the yoke ?

Harald.
