            IBM/PC & Compatable Manual Addendum     Version 2.0


Copy the software to your hard disk.

         C:\>   copy a:\*.*     or    copy b:\*.*

Plug the transmitter into the serial port

Run the program     rc    

At startup the left transmitter button toggles the idle up function if flying
a helicopter and it toggles the landing gear if flying an airplane. The right
transmitter button toggles the zoom view. "B" restores the left transmitter
button control of idle up. If in autoratation modes, "B" will cause right
button to toggle idle up.

Parameter files are stored to and read from the current drive/directory. This
is the drive and directory that was current when R/C AeroChopper was run.

Push "k" to enter chase mode 1 -  Push "k" again to enter chase mode 2

Push "k' a third time to return to the fixed camera mode (the camera
position will remain where you have flown to)

You can mix the chase modes with the camera control modes ("F10")

When in a chase mode you can push "L" to return to the fixed camera
and also return the camera to its origonal position

Push "s" to spread out the ground objects
Push "s" again to spread out more (up to four times)

On slower computers, farther (smaller) objects will increase the frame rate
     
Push "F" as many times as needed to return objects to normal positions

Push "V" to turn off many background objects - this will speed
up the frame rate and control response - most usefull for slower  computers
    
Push "T" to toggle the mountains between two colors and on and off

Push "C" to change the aircraft fill color

Push the "Arrow Keys" to move the camera. In the fixed camera (chase mode 0)
the up and down arrows move the camera up and down. In chase mode 1 the up
and down arrow keys move the camera in a circle around the aircraft. The
left and right arrow keys move the camera in a circle in both chase mode 0
and 1. These arrow keys will move the camera 30 degrees around the aircraft
for each button push. If you hold the key down the program will keep moving
the camera until several seconds after you release the button.

push "*" to turn off sound            push "/" to turn on sound

Push "1" to enter single step mode
Push "G" to make left transmitter button a landing gear control

Keys not used on PC version - "Delete", "(", ")", "Alt A", "F8"
There will be no missles, bombs, or moving targets in the PC version





Version 2.0 Changes

2 New helicopter images:   Jetranger  and Concept 30SR
2 new airplane images:     Steen Skybolt and Finesse
Push F3 to change image

SoundBlaster supports 6 different aircraft sounds with an optional
muffler for each sound.

      New Parameters       Sound Type    0 = use PC speaker
                                       1-6  select aircraft sound

                           Muffler       0 = No Muffler
                                         1 = Muffler

                           Engine Torque (airplane)  1 = no torque
                                                  9999 = max torque


      New Keyboard keys      "9"         Change sound
                             "8"         Toggle Muffler on or off


                             "4"         change helicopter rotor display
                             "5"         change tail rotor/propeller display
                             "F2"        reset aircraft to start

                             "7"         Pin Aircraft - this key keeps the
                                         aircraft in a fixed position over
                                         the ground. The aircraft can rise
                                         an fall but remains over a fixed
                                         ground position. Push "7" a second
                                         time to release aircraft.


There are 8 new parameter files on the disk with new airplanes and helicopters
Push the "Read Parameters from Disk" button on the Main Menu to load the
files.




 























              R/C AeroChopper Connection to a Serial Port


The R/C AeroChopper "transmitter" plugs into a standard RS232 serial port.

Most IBM/COMPATABLE computers come with two serial ports installed. These
use either a 9 pin male connector or a 25 pin male connector on the computer.
The 9 pin connector has two rows of pins, one row of 5 pins and one row of 4
pins. The 25 pin connector has one row of 12 pins and one row of 13 pins.
Common uses of serial ports are for a serial mouse or for a modem.

The R/C AeroChopper "Transmitter" comes with a 25 pin female connector. You
may use a standard 25 male to 9 female adaptor in order to plug the
"transmitter" into a 9 pin serial port on your computer.

Plug the R/C AeroChopper "transmitter" into a serial port and run the program
   rc  . If the software runs correctly you do not need to read the rest of
this serial port information.

The software will search for the transmitter in all combinations of
Com 1, Com 2, Com 3, and Com 4, using either IRQ (interrupt request)
3 or 4. If your "transmitter" is sharing an IRQ with another device,
the program will temporarily disable the other device's interrupt
while R/C AeroChopper is running.

You can specify the port number and IRQ number as follows:


     TYPE AT DOS PROMPT                   RESULT


     rc 3 -IRQ=5                          use COM 3  and IRQ 5

     rc 4 -IRQ=7                          use COM 4  and IRQ 7

     rc 2 -irq=2                          use COM 2  and IRQ 2 


Please note that you must have the hardware in your computer set up correctly
with switches or jumpers so that if you use the following:   rc 4 -IRQ=7  ,
you must have the transmitter plugged into a serial port that is set up
as COM 4 and set to use IRQ 7 for correct operation.



























NEW PARAMETER  "Manual Camera"  if set to 0 the mouse is used to control
the manual camera as described in section 5.27, 5.28 and 4.6d. If
you change this parameter to 1, the computers gameport (joystick)
is used to control the manual camera.

NEW PARAMETER  "FUEL" is the fuel supply in seconds.
Push "N" to refuel the tank.



 TWO NEW HELICOPTER AUTOROTATION MODES

 Two new autorotation modes have been added. The parameter " Autorotation on"
 on page 4 of the helicopter menu can now be set to 3 and 4 in addition to
 the old 0, 1, or 2. Modes 3 and 4 are identical except for the tail rotor
 function. In mode 3 the helicopter has no tail rotor control while in
 mode 4 there is tail rotor control. In modes 3 and 4, enter the new
 autorotation mode by turning off the engine by pushing the left transmitter
 button. The autorotation characteristics are now influenced by 4 parameters:

             - Rotor Mass
             - Autorotation Efficiency
             - High Blade Pitch
             - Low Blade Pitch

 You can autorotate either upright or inverted. Control the collective
 pitch with the throttle joystick control. The collective pitch can be
 controlled within a range set by the two new blade pitch parameters
 described below. When autorotating upright, a negative pitch will increase
 the blade rpm at the expense of an increased rate of fall. When autorotating
 inverted, a positive pitch will increase the blade rpm at the expense of an
 increased rate of fall. When autorotating upright, a positive pitch will
 increase the lift at the expense of a decrease in rpm. When autorotating
 inverted, a negative pitch will increase lift at the expense of a decrease
 in rpm. Be sure to keep your blade rpm high enough for controlled, safe flight



 TWO NEW HELICOPTER PARAMETERS  (on page 5 of the heli menu)


   High Blade Pitch (0-15 deg)

         This parameter defines the maximum collective pitch when autorotating
 in autorotation mode 3 or 4 (Autorotation On = 3 or 4) after turning off
 the engine by pushing the left transmitter button.


    Low Blade Pitch (-15 - 0  deg)

         This parameter defines the minimum collective pitch when autorotating
 in autorotation mode 3 or 4 (Autorotation On = 3 or 4) after turning off
 the engine by pushing the left transmitter button.
