I buy PILOT version now, will I be able to upgrade to higher versions
Yes. You will
have to pay just the price difference between two versions.
PILOT a "basic" or "light" version, PRO being a "full" one?
No. PILOT is a
full version with every feature enabled for normal flight operations.
It is by no means "basic" or "light".
PRO version is an extension of PILOT adding some hardcore features for
abnormal operations, which would be intersting to very experienced
about framerate? Do I need a top-end PC to run Majestic Dash smoothly?
Any PC that can
run FSX will be sufficient to run MJC8 Q400. The external FDE and other
systems are calculated in other threads than the FSX's one, they can
also run on different CPU cores. In fact, the MJC8 Q400 is much lighter
on frames than comparable add-ons, it is usually
just few fps less than default aircraft.
2D panels included in PILOT version?
panels are included starting from PRO version. Nevertheless, all
displays (EFIS, FMS, ARCDU) can be un-docked in
2D windows and placed anywhere on the screen (or on other screens) - in
all versions, including PILOT.
PRO version will be released?
several months after the relase of PILOT, but as with any other relase
date we won't be giving exact timeframe
you consider new liveries requests?
No, but there
will be a special thread on our support forum where third-party
painters will share their work

then TRAINING. After that, we will work on the Bombardier Q100-Q300

Due to the changes in our licensing system, the older installers of version 1.005 - 1.008 should no longer be used.
In order to install the Q400 from scratch:
1. For download editions: Download the new 1.010 version installer from your software store (free of charge)
2. For the boxed editions: Please login to support->User Area section on our website and download the version 1.010 full boxed edition installer

Attempt to run the installer with the right click, "run as
administrator" option, make sure you are not copying any spaces with the data. Repeat the attempt after a few minutes. Our
servers might be busy handling too many concurent requests
Make sure you are only entering a single word as your last name, it is suggested not to use any non - ascii characters.
If still no success, contact email@example.com for

If you think, you might have selected "No" when asked by FSX
about trusting the gauge mjc84main.dll gauge, you will have to purge
the trust record in the fsx.cfg.
erase the following line :
If still no help: Make sure your FSX is of version SP2 (or
acceleration).Please note, that SP1 patch must be installed before SP2
or Acceleration installation is attempted. Failure to do so might
result in the problems running the Q400
Install the Dash-8 with right click, "run as administrator"
option from the same drive where your FSX is installed
Attempt running the FSX itself with the "run as

Make sure you don't have a USB sound device (aka headset)
set as your primarily sound playback device in Windows
Dash-8 might also be sensitive to your sound card drivers,
or the speaker configuration, due to the utilization of DirectX sound

this seem to apply to Realtek sound devices
If nothing else helps, I could also suggest reinstalling the
FSX - if it is possible. (There are addons which would modify the FSX
default libraries), we've seen the cases when the FSX reinstall fixed

If you still have a problem after this, the next suggestion would be to
check your computer CPU cores to make sure your FSX, when ran with some
default aircraft, is not using all of the cores for 100% about once per
minute for 10-20 seconds. If this is the case, you might need to change
the affinity settings of the FSX to free at least 1 CPU core.
can I send to MJC support to help them resolving any issue?
Please check if you can see the following file:
CMJC84BaseErr.log in the root folder of your
FSX. If there is one, please email it to firstname.lastname@example.org
along with the description of the problem, as this can help us to
resolve your issue.

"slewing" the FSX as you fly. This kind of integration can not provide
the smooth momentum, as the momentum accelerations of the FSX are not
accessible. Thereforе we had to disable it. We think this is a small
price to pay for the realistic flight dynamics.
to verify which version of the Q is installed on my computer
version 1.007, the software version can be checked on the ISI screen.
Turn all the electrics off, click on the ISI (standby instrument)
screen to bring up the pop-up, turn the batteries back on. The version
of the software will be indicated in the A/C field (1007 or above) for
a few seconds.
Under P3D the sounds for external and VC views are the same

initial state corresponds to the state in which airline pilots usually
find the plane (i.e. GPU connected, electrics and air cond switched
on). If you want a Cold-and-Dark situation, bring the aircraft to cold
and dark by switching off all AC and DC switches, then save the
situation. The next time you load it, you will find the plane cold and

the rudder almost doesn't steer?
The Q400 has two ways to control the steering wheel, both under 40 kts.
- with rudder pedals : this controls the wheel in -8°..8°
range and is mostly used at takeoff;
- with the tiller : can turn from -70° to 70°.
Since the rudder axis is used for the first steering method, it
cannot be used for both, so we had to map the tiller to any other axis.
We chose aileron axis (as ailerons are useless on ground) or spoiler
axis (not used at all on the Q400). In any case you can always control
the tiller with the mouse (clicks or wheel) but this method is the less

Make sure the

select the first point into FR and the second into NX.

to adjust them for the full range travel. Q400 will not function
Aircraft banks to the left
This is normal
for a turboprop aircraft and is due to propwash hitting the tail fin.
Use the rudder pedals to compensate for this effect on takeoff and
landing, and the rudder trim in the other phases of flight. Please note
that this effect diminishes as the airspeed increases. Refer to slip
skid indicator on the PFD (two-section triangle at the top of the
attitude ball) - try to align both sections.

the selected altitude is below the current level. Note also that VNAV

PRO EDITION questions
I don't plan to use the HUD during my flight, is it possible to remove it from the Virtual Cockpit ?
Yes, it is possible to select the HGS/non-HGS version of the aircraft from the MJC84 Control Panel, FLIGHT CONFIG page. After that the Q400 must be re-selected or the flight must be re-set.
I have the Pilot version already installed. Do I have to un-install it before installing the Pro version ?
It is not necessary to uninstall the previous copy of the Q400, since the installer will do it automatically anyway
I'm flying on auto pilot and switch to outside view,when I go back to the cockpit, it disengages the auto pilot
That particular joystick button which is used to switch the view is probably assigned to the autopilot disconnect via the joystick connector of the Q400. Please open the ini/mjc84.ini configuration file, scroll to the end of the file and set the correct button for AP Disconnect, or erase the assignment completely
Upon takeoff, the landing gear won't retract
PRO edition of the Q400 includes the Gear Pins simulation. Availability of the gear pins in the Situ (a bag located behind the First Officer seat) must be verified before closing the doors and starting the engines on the ground - as per the checklists. Gear pins can be stowed by clicking the Situ with the mouse, or using DATA->SERVICES page of the FMS
