Most of the questions we get are about things we don't even make. Many people
ask questions about graphics cards, monitors, joysticks, rudder pedals, etc.  
You should always ask the manufacturer those questions. Many manufacturers
also have support forums that can help.

look at all discount requests every week or two.

Q:  How much does it cost to build one of these?
A:  Material costs vary around the world, however, there is a materials list available for most DIY
Flight Sims projects. Check the product description and click the link for materials.

The link looks like this:

Q:  What is the difference between the
Desktop Airliner cockpit, the Easy Airliner cockpit and the
Universal Airliner

Q:  Where can I find EPS or XPS?
A:  Most materials can be found at
Lowes or Home Depot, or your neighborhood hardware store.

Q:  What is EPS?
A:   It is Expanded Polystyrene.  Please see more info
about it here.

Q:  Can you just build it for me and ship it?
A:  Not at this time.  In most cases, the materials have already been shipped to your town and are
at your local home improvement store.  This saves you money.  It would cost you a lot of money for
me to manufacture something in my basement and ship it to you.

Q:  How much is the MAACS moving flight simulator?
A:  MAACS was a big research project to explore a
moving flight simulator platform and a virtual
reality headset.  It's not a DIY project.  If there is enough interest, we may develop a DIY moving
flight sim platform in the future.

Q:  Hey!   what is the price and availability if the helmets?  thanks
A:  We aren't selling the virtual reality helmet.  It was just a fun experiment.  We do a lot of

Q:  I can't find any EPS at the stores near my house, what else can I use?
A:  Other DIY builders have had success with
XPS, (extruded polystyrene) or thick cardboard, foam
board or foam core.

Q:  How sturdy is that flight sim?
A:  Sturdy enough for flight simulator, not sturdy enough for real airplanes.

Q:  I see that you use the CH yokes do you recommend this product over the saitek yokes or can
you advise which would be better to buy as im just starting out
A:  We don't recommend either product more than the other.  Honestly, no computer yoke is like the
real thing.

Q:  hey! i seen that in some of your flight sims you have 2 keyboards in 1 pc is that possible for
windows xp and if so hw do you do it. thanks
A:  Some of our videos include instructions for using two keyboards.  If you see a picture of it, then
we include it with that video.

Q:  What are the 10-16 x 1" screws you mention in the plans?
A:  For the 10-16 x 1" screws, the 10 is the size of the head.  The 16 is just the thread count (16
threads per inch).  The thread count is not a vital piece of info, you might find screws with an 18
thread count, or you may not know the thread count at all.  I've used both #8 and #10 size screws.  
Either one will work.
The two important ideas about using screws with PVC pipe are this:
1.  Get screws that are self-drilling (or self-tapping as some folks say).  That saves you from having
to drill pilot holes every time you attach a screw.
2.  Get screws that are either 3/4" or 1" long.

Q:  Can you make a DIY rudder pedal tutorial?
A:  No. There are already several commercial off-the-shelf rudder pedals available from Saitek, CH
Products and Logitech that are very good. I don't want to "re-invent the wheel" because I  end up
spending more in resources, time, and effort.

Q:  I saw the DIY projects on your website, but do you have (description of something not on the
A:  I'm surprised at how often I get this question.  Does anybody really believe that I would spend
enormous amounts of time and some money developing a DIY project only to keep it secret?

Q: How large is the
T440 Triple Screen Flight Sim?
53.5" wide (but the monitors extend a bit out to the sides to 56")
66" tall
34" deep

Q: Where can I get that plastic light bulb protector for the Missile Lamp?
A: Home Depot, item #81920 (Westinghouse 5 1/2" x 3 5/8" Polycarbonate Threaded Neck Shade).

Q: What are the outside dimensions of the
E430 DIY Flight Sim Pod?
98" long (or 116" with the optional tail boom).
48" wide
66" tall

Q: How large is the HDTV in the
E430 DIY Flight Sim Pod?
A: It's a 40" HDTV. I used a Westinghouse model UW40TA2W, but it doesn't have to be this specific
model. The HDTV is 36.75" wide and 22.5" tall.

Q:  How do I get flight sim to work on two monitors?
A:  We have two free videos that can help.  
Part 1 and Part 2.

Q:  How do I get flight sim to work on two monitors and Windows Vista?
A:  We understand that's a problem.  We recommend the Matrox Dual Head2 Go
or Triple Head2 Go for multiple monitors.

Q:  Where did you buy that yoke and throttle quadrant?
A:  Check our
Online Store powered by  You will find everything
you see in our videos:  joysticks, throttles, rudder pedals, yoke, throttle
quadrants, VR 920 Virtual Headset, as well as a lot of software, FSX add-ons
and even movies.

Q:  You showed in one of your videos that you had dual controls. I have two
questions reguarding this.
1. Do they both move when used?
2. Which yoke does the computer read from?  Thank you in advance. Keep up
the good work.
A:  You have a sharp eye.  We have used dual control yokes in the past.  
We used CH Products USB flight sim yokes plugged in to two different USB
ports.  They are not mechanically linked so they do not move together.  The
computer recognizes a command from whichever yoke is moving at the time.  
For example, if the left yoke is moving, the computer pays attention to the left
yoke only.  If you stop touching the left yoke, then move the right one, the
computer then gets its commands from the right yoke.  One or the other, not
both at the same time.
Actually, this works out well because we don't want both pilots trying to fly at the
same time either in a simulator or in a real airplane.  

Q:  Hi, I bought a video card, nvidia 8400 512gb and the  card I had before,  an
nvidia 4000 128gb was running my simulator better then the one i got now!

A:  Please contact the manufacturer's technical support.

Q:  I have two computers and I am getting ready to run FSX delux on both I
would like to know how do I get them to run at the same time so I can multiply my
simming experience....I want to network the computers to work at the same time.
A:  Try
Peter Dowson's website.  He offers software that makes this possible.

Q:  Is there a way to download the free videos that you have on your site?  I'm
trying to save them but they won't let me.
A:  The free videos are online only at this time.

Q:  What cool products you have. I am curious if you ever used any of your toys
with flightgear ? I am a Linux user so that is the only Sims for use here.
