Hot on the heels of the FTX Pacific North West region pack, comes the first in a new series of high resolution airfield sceneries for this area, Stark’s Twin Oaks 7S3.

This scenery is the pride and joy of Bill Womack who is a well known and regarded developer. He lives in the region and has always wanted to model this beautiful location. With joining forces with Orbx he now has the toolset and expertise to realise his dreams.

Hopefully, by now, after reading my previous FTX reviews, you will already be the proud owner of a FTX Region Pack so you will be familiar will the FTX Central interface and the FTX Aero tool which introduces new runway textures, and taxiway markings etc. More details of the region interfaces can be seen here. However, I will detail the 7S3 control panel below.
Stark’s Twin Oaks is a small family run rural airfield nestled between a hazelnut orchard and an alpaca farm on the outskirts of Portland, Oregon. Formally a dairy farm it was discovered by Bob Stark who saw its potential as an airport. After much improvement of the land the runway was built and hangars added. It has been developed further with the addition of more aircraft shelters and workshops etc.

This is one of those places that pilots come to at the weekend to enjoy their hobby, so the skies, weather permitting, are busy with GA aircraft. The field is also a popular place to practice on weekdays when there are several CFI’s offering instruction.

The Region
For pilots looking to explore the Pacific Northwest, Twin Oaks is an ideal base. The Pacific coast lies just beyond mountains to the west, to the east, past Portland, is the entrance to the Columbia Gorge, where the mighty Columbia river cuts through the Cascades Mountains. There are a couple of other mountains are nearby if you fancy a longer adventure, Mt. Hood and the more famous Mt. St. Helens.

There are plenty of interesting sights to be seen, even without a flight plan so you can just go off exploring but don't loose your way! If you are also using the PNW region pack you are going to see these sights in some detail.

The Product
To get the best from Starks Twin Oaks 7S3, Orbx’s advice is to have PNW installed as a base pack. This will give you extra features such as 3D street lighting and moving traffic on all roads, custom houses, trees and other objects. Another consideration is the scenery blends perfectly with the base textures and surrounding terrain. Without it, the transformation from the default scenery to the Orbx scenery is abrupt to say the least. I must stress however that 7S3 can be a stand-alone product.

Extent Of The Scenery

One thing you never feel with FTX scenery is short changed.  Nearly always, along with the high definition airfields you get either a town or extensive detailed scenery that you probably weren't expecting, this just goes to show what excellent value these airfields are.

Download & Installation
Download size is around 357Mb and you will need to allow ~370Mb of spare disc space to install it.

Once downloaded, the installer will ask you for your Order Number, Date and Key to validate the installation. Most Orbx-FSS customers will be familiar with this process.

The scenery will add itself to the scenery library automatically and a manual will appear in you Orbx/documentation folder as well as FTX Central if you have that installed.  If you do not have FTX already installed then you will have to manually add it to your scenery library, this is also explained in the manual.

Make sure you read the manual all the way through. For the “newbie” there is plenty of set up and performance advice. As part of the setup you will have a Control Panel for the scenery. You should have a desktop shortcut as well as a path from the FTX Central utility if you have a region pack installed.

One of the most important display settings is the mesh resolution, in order to enjoy the unique (and worlds first ever) multi-level airfield elevations a 2m mesh setting is required. This doesn't really have any performance hit so you would be daft not to!

Incredibly detailed fuel station.

7S3 Control Panel
The control panel allows you to switch off and on individual features such as airfield clutter, Alpacas, custom trees, AI traffic and of course the ubiquitous FTX 3d grass! By default all the features are switched on and other than the tree season selector, they are probably better off left that way unless you need to claw back some processor overhead.

Tree Selector
There are some very high quality GMAX built trees included. These are located close to the airfield but they are not seasonally aware. They have three variations, Spring/Summer Fall and Winter which has to be set before running FSX. The only downside to this is if you forget to change them and get unseasonal foliage. 


Exploring Starks Twin Oaks
The detailing of the airport really is astounding. I took BOB for a walkabout to see the features close up. 

The entrance to Twin Oaks airfield hosts the old airport sign you can see above in the review banner, the driveway takes you straight ahead to the Stark’s own house, a nicely featured building with a veranda and multiple levels to the basement. 

At the back of the house there is the airport office, initially this gives you a feel of a small farm strip type airfield run on coffee and cookies!  From the veranda of the house you get a great view of the threshold of 20 and from here you can watch aircraft in the final stages of approach and queuing up to take off.  The AI seems to work well here and follow the established pattern.

Opposite the house is a garage block with basketball hoop and mind the children sign, this seems to mark the boundary of the residential area. You then pass a collection of farm type buildings on the left dominated by a lofty triple grain silo, these silos are very distinctive and help with orientation when flying locally.

As you proceed further, a multitude of buildings and hangars soon belie this farm strip feeling. There are many aircraft in various stages of (dis)repair within the hangars and workshops.

At the end of the track there is a clubhouse which has a raised seating area that overlooks the field. This is another great place to watch the world go by, from here you get an idea of all the different terrain levels which need that 2 metre mesh setting to show correctly. As the land falls away from the clubhouse the runway is raised considerably at its southern end to maintain its elevation.

On the eastern side of the field are terraced rows of hangars for aircraft based at the field. These are pretty anonymous looking structures so a pretty accurate representation really!  There are plenty of tie-downs on the grass for ad-hoc parking.  Down below the viewpoint from this deck and off to the left is a large maintenance hangar and a highly detailed fuel station. There is a fuel box here so by taxiing up you can fill the tanks.

Away to the western side is a hardstanding type apron with tie-down area.  Behind this and further down a slope is the Alpaca farm with static animals feeding, they is on another level lower than the runway and helps to demonstrate the multi elevations here.

Finally, from this viewpoint you can see far into the distance and you notice a lot of the outlying properties interspersed all around with very nicely modelled trees.

I didn't see any reference to, or evidence of, FTX soundscape however there is an ambient noise everywhere within the airfield boundary interspersed with engine noises from the AI. I guess I have been spoilt at other FTX SP3 airfields by hearing sounds allied to my location.

Flying around 7S3
One thing I like about these series of airfields is there is always plenty to discover in the immediate vicinity.  The river that runs to the south is finely modelled and will take you past the threshold of 20 so is always a handy feeder route.  Beware though, as there are noise abatement procedures in place. Left hand circuits only!  If you are unsure, there is a notice board at the hold of the southern runway to remind you.

Further afield to the northeast is a distinctive highly detailed quarry which is a good VRP for the airfield. In other directions you can enjoy general farm type scenery with custom buildings. On every circuit you will notice something different, so make sure you get to take off from both directions!

Inbound to Starks

Beyond this you are out of the reach of the airfield scenery and if wise, you will have already bought and installed the Pacific North West region pack so the enjoyment will carry on until you get to your next scenery area.

Lighting / Night Lighting
7S3 takes advantage of the FTX 3d lighting from the region pack along the roads and into the distance, as with their other sceneries this really adds another dimension.  There are many areas of light emanating from buildings which look just about right, there is no apron floodlighting so it is a bit eerie at night.

I found the REIL lights and runway edge lights only worked approximately 30 minutes before dusk and at night. In the real world this airfield has automatic lights which turn on with 5 microphone pulses when tuned in to 123.05.  I didn't expect this to be replicated here but the absence of the lights in the day made the airfield more difficult than necessary to find when inbound.

Looks great at dusk, notice runway lights illuminated
My review is based on the V1.1 version that includes the free update available from the FTX website support section.

Twin Oaks and the latest Orbx objects library (Also available from the support page) both benefit from their own proprietary TextureFlow technology.   My understanding of this is that the optimisation of the textures now virtually eliminate texture lag and therefore can contribute another 5-8 FPS depending on your location.

With my FSX settings set to what John Venema recommends in his TextureFlow video blog I enjoyed frames from 23 -31 and it remained smooth throughout and knowing what definition I was enjoying, I am more than happy with this.

Away from the airfield I had a slight increase in frame rate but not really that much. After tweaking down the quantity of trees per cell from 4500 to 2000 there was a marked increase of around 10 FPS, so sometimes it pays to experiment!

I really enjoyed reviewing this little airfield.  I can see why Bill Womack fell in love with this place, it's the airfield I would like in my back yard!

High quality is a word always associated with Orbx sceneries and this lives up to it in spades. The multi-elevation is very impressive and is a screen-shotters heaven. 

My only disappointment was the runway lights, I scanned the forums and found no mention of this so I wonder if it is just me?  The sound was ok but I would have thought soundscapes would have polished this one off nicely.

Overall, I award this a Mutley's Hangar score of 9/10 Well done Bill Womack and the team at Orbx!
