I did not find volumetric shadow in the menu.... But when I enable Rembrandt for renering, the second airplane is gone. It looks nice now :D
Next problem ist the motor.... Has anyone had luck to start it?

Under "Aircraft Options" then un-check "Show Shadows". Either that or turn on ALS in the rendering settings, that would be View/Rendering Options/Atmospheric Light Scattering (ALS).

To start, turn on switch Alt and Bat, mixture to 100% (that is pushed all the way in), throttle to 25% (3/4 way out). Then use the key to start. It fires right up after a few cranks.

This is a gem in the making, I am really impressed with the work done to this point. I can't wait for more progress.

Thanks

wlbragg, thanks a lot, it worked!
The problem with the motor was, that I used the "s" key to start the engine. This was wrong, as you sad, with turning the key to start did the trick.

Flying is very nice, I have to try it some more, but I already know, that I will fly it a lot. Thanks for all your work.

Thank you very much for your feedback. I will ttry to continue the development this weekend. I haven´t much time to do this, but im learning a lot about flightgear with this Project.

Best regards

Hi, some news. A minor update in git repository with the following features:

Aircraft menu:
Autostart option Is operative now.
New aircraft options dialog, based on excelent c182's. You can show/hide wheel fairings, yokes and ALS aircraft shadow.
About dialog, based on c172p dialog, with direct access to git repository clicking on a simple button.

Shadows:
ALS Shadow: have de correct model and layout, now.

Model:
Cabin floor is textured

Instruments
Improved magneto and starter (Made by D-ECHO) I hope I did the merge correctly. I do not have much experience with github. :(
New elevator trim wheel added to cockpit

Indeed, i've freshly downloaded the plane from the github repo and take a ride on PAJN (Juneau Intl, Alaska, USA). Im limited with aircraft testing but i can say is an absolute new and improved version from the default availible, worked fine for me from startup until landing, parking and switch off. Just hoping more progreses to that beautiful plane! Thanks - Muchas gracias!!

Hi,

I just joined the forum to say that I really like this Cessna 152 II project, because this is the airplane that I am flying right now in real life! The model looks really great, and most of the switches and features function flawlessly.

I just have a few critiques and requests below that are probably known by the developers, but I thought I would mention them in case you have a wish list:

I think the model is a bit over powered. It climbs pretty fast compared to real life, and with the power off, the model drops like a rock. I think the real life 152 is 8:1 or 9:1 glide ratio.

The elevator trim is a bit sensitive, and a 'take off trim' notch/marking would be awesome.
I think there might be a ton of elevator authority at slow speeds near the ground compared to the real 152.
I didn't see a compass. Maybe it is in a different place and I missed it.
No RPM/horsepower drop when using a single magneto or when carb heat is turned on
the turn coordinator ball is to the right when on the ground.
no fuel primer yet. Maybe this is better, I always forget to prime the 172 and 150 in flight gear.
A hobbs meter would be awesome, so I know how much time I spend flying the 152 II :)

Just some info that might help on the flight model:
Game: Cruise Speed 75% power at 8500 ft MSL is 90 knots
Real: Cruise Speed 75% power at 8500 ft MSL is 107 knots

Game: Rate of Climb ~1400 feet per minute at 67 knots at sea level
Real: Rate of climb 765 feet per minute at 67 knots at sea level

I haven't tested the glide distance for numbers yet, but it feels like a brick with the power off. I know that in real life, I can glide into a base leg and short final with the engine off from downwind abeam the numbers at 1000 AGL.

I've never worked on a game flight model before, but my intuition would guess that reducing available engine horsepower and reducing drag would put this better in line with the real plane.

I also wonder about the turn coordinator ball. This seems to malfunction in all of the airplanes that I have flown in flightgear, Maybe there is no way to fix it in each particular model. When applying right rudder to counteract engine torque and P-factor (especially during takeoff climb), the ball goes way to the side. In real life, applying right rudder should center the ball rather than push it outward.

Just in summary:
I really like this 152 model!!! keep up the awesome work!

Wonderful feedback. This is extremely valuable to the developer, a real life pilot critiquing the model VS the real thing.

I've been watching this build from the start and I too am impressed and wish to see it progress.

Go to https://github.com/awall086/c152

Click "Clone or download"

When unzipping, remove the suffix from the file name so that the folder just says "c152"

Put it with the other airplanes. Mine went to \Documents\FlightGear\Aircraft\org.flightgear.fgaddon\Aircraft\
