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.

Q: Your projects are awesome... but I still want a discount.
A: Discounts actually take more of my time because the order must be
generated manually. If you're asking for a discount please be patient. I usually
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: 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:  Hi, I want to modify your design to include a ... (description of what you want to build).
A:  That's very cool and you may notice in the
Customer Gallery that many customers modify their
projects to meet their needs. Unfortunately, it's difficult for me to imagine how a particular
modification will work unless I actually build it. That's prototyping, but PVC pipe is great for
prototyping! You can assemble and disassemble a frame many times until you find a design that
works for you. Then, lock the fittings in place with self-drilling screws. Furthermore, if you want to
change the design months or years from now, you can still remove the screws, remove the fittings
and make whatever changes you want.

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:  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 of the virtual reality helmets?
A:  I'm not selling the virtual reality helmet, it was just a fun experiment.  We do a lot of experiments

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:  Do you recommend CH yokes or Saitek?
A:  I 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 thickness of the screw.  The 16 is 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 say).  That saves you from having to
drill pilot holes every time you attach a screw.
2.  Get screws that are either 1/2" to 3/4" long.

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: Why do you use latex paint instead of spray paint?
A: These are the reasons I don't use spray paint:
1. I've tried it before and it was very frustrating, it's too easy to miss spots when spray-painting a
structure made of tubes.
2. Most of my customers (and me) build these projects indoors where there is not enough
ventilation for a lot of spray paint. I don't want to encourage people to kill brain cells or get
overspray in their apartment, so I use indoor latex paint... tinted primer, actually.
3. I think the latex primer tends to seal the fittings to the pipes in a way that enamel spray paint
would not. It could be my imagination, but it seems that a structure painted with latex is a more solid
than an unpainted structure.
Q:  How do I get flight sim to work on two monitors?
A:  We have several free videos that can help. Some
newer videos are here and the older videos are

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

Q:  You showed in one of your videos that you had dual controls. I have two questions regarding 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!   What could be happening?   Its four times
better and it doesn't run it better then the 128  Please help me! What can i do.
A:  Please contact the manufacturer's technical support.

Q:  I have two computers and I am getting ready to run FSX 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:  I have a question about (general question about flight simulator)
A:  Checkout our
Guide for Beginners and the Introduction to DIY Flight Sims

Q:  PVC pipe is so expensive where I live.
A:  There is a
video here that shows one source for buying PVC fittings online.

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.
