Default DC-3 wheels continued

Okay, kind of fixed the contact points issue that I started out with, but now the gear won't go up. At least they won't visually. If I go to raise them, they just stay down, but if I try to land like that it bellys in. But if I use the gear lever to lower them, I can land on the wheels. But I'm getting tired of flying around with the wheels appearing to be down and locked when they're not.

I had the bright idea that maybe the model got corrupted somehow, so I made a brand new default FS9 install with no mods, copied the DC-3 model folder contents and pasted them into the messed up default DC-3 model folder and no joy. At this point I'm thinking that in my monkeying with the contact points, that maybe I got screwed something up.

Here's the contact points section from the Aircraft.cfg file:

[contact_points]

//6 Wheel Radius (feet)
//7 Steer Angle (degrees)
//8 Static Compression (feet) (0 if rigid)

gear_system_type=0

Any thoughts? Suggestions?

Take a look at this line:

gear_system_type=0

I think that is set to fixed gear.

Replace it with this one (copied from my default DC-3):

gear_system_type = 1

It's always those tiny little details that bite ya in the butt and are nearly impossible to find.

Thanks Tim, I just compared it to the new install default and it's a 1 there as well. Off to change and test.
 
Well, that didn't work out as planned. Made and saved the change, fired up FS and took off from Memphis. The screen shot is with the gear supposedly in the up position. Landed like that and bellied in as before.

I'm thinking at this point that my best bet might be to copy the DC-3 from the new stock install, put the FM I've used for years in it from a fresh download and copy my paints, panel & sounds into that and see what happens. The shotgun approach does work most of the time and it'll give me a fresh DC-3 in the bargain. The downside is that I'd never know what caused the problem in the first place.
 
Just got through with rebuilding the default DC-3 with the Farmboy FM and my panel, paints and sounds. THE WHEELS GO UP! The shotgunning of the problem fixed it, but darned if I know what was wrong in the first place.

Guess this was the DC-3's revenge for my having let it sit ignored in the hanger for so long! :d

Tim, I looked further into this and while I don't know what 0 =, 1 is Hydraulic. Maybe 0 is Electrical?
 
[hydraulic_system]
Willy, could have been a hydraulic pressure or engine mapping issue, and the type 0 probably would have worked had you changed the electric pumps=0 to 1. I have listed the gear system types from the sdk.

normal_pressure = 732.0 //PSI
electric_pumps = 0 //no electric pumps
engine_map = 1,1,0,0 //pumps on Eng1,2

gear_system_type=1 This parameter defines the system type which drives the gear extension and retraction.
0 = electrical,
1 = hydraulic,
2 = pneumatic,
3 = manual,
4 = none.
 
Thanks Milton. If there's anybody that knows how landing gear function in FS, it's you!
