@zacarias Hi, only added a texture to the wheels, never modified the 3d model or fdm but, I'm going to check the problem and try to fix it

I'll also look for this issue, and report.

I only changed the 3D of the wheels, and textures, No FDM changes were made to gears.

Kind Regards,

zacarias: you are completely right. I have noticed all of those errors, I will attempt to solve them. it0uchpods made a commit a while back on the FDE, but I think he made the rudder not sensitive enoguh and the elevator too sensitive.

Hi.
I want to ask one think.
After I downloaded a new version with new dynamic thrust system, the aircraft is really really hard to climb at FL300 and above. At FL300, if I use FLCH, it only gets 1400 fpm and continue decrease when the aircraft climbs higher above FL300.
Why?

It is normal that the climb rate falls, the higher one climbs and more the air rarifies, the temperature falls and it will be required lot of push to reach the Cruise altitude. Can you explain us how you proceed?

Okay. But, is it normal that the v/s drop until about 200 fpm. This morning, I flew a route. The cruise level was FL350. When the aircraft was around FL330, the climb rate was below 400 fpm with climb thrust was about 94.4%. Then, I decided to change the a/p mode from FLCH to V/S mode. I thought the thrust should be around 98%, right? CMIIW.

This is correct behavior. Jet engines get weaker the higher you climb.

That means that your proper cruise altitude should be FL330 :)
The 737 does need a lot of stepclimbs compared to the 757.

Do you remember what was your Gross weight ?

To be so limited in VS around FL 330, you had to be fully loaded with Fuel and Pax, or experiencing severe windshift from head to tailwind :)
Try best rate of Climb speed in level change, typically around 260kt/M0.76 for 37-800

Hey guys, awesome work still! She's looking and sounding gorgeous!

Just a minor error I've spotted - the AutoStart works fine apart from turning the Gen buses on - you end up with a working plane but no MFD/PFDs.

Cheers! 8)

Edit: I'm on the latest (as of this post) version from here: https://github.com/YV3399/737-800YV.git

Hello people
Lego added a new electrical and did not connect it into the autostart, now is fixed.

Kind Regards,
