Thank you for purchasing the Venom VR3T 2.4 GHz
Transmitter. The VR3T 2.4 GHz Transmitter has all of
the great features of its FM predecessor including 3rd
Channel Mixing,16 Model Memory, and thumb switch
activated Programmable Steering Dual Rate, with the
stability and reliability of 2.4ghz technology. With the
freedom of 3rd Channel mixing, the VR3T 2.4 has
so many high-end features you won’t need to look
anywhere else for a 2.4ghz transmitter.

NOTE: Make sure the polarity of the 8 AA Alkaline
batteries are correct when they are put into the
transmitter.
In order for these settings to be programmed into the VR3T 2.4 the following steps must be followed.
1) All model components must be connected correctly. Starting with the receiver, servos, and power supply.
2) The steering and throttle trims on the VR3T 2.4 are set at neutral.
3) Always make sure to turn on the transmitter rst before turning on the receiver.
4) Make sure the transmitters antenna is installed for best input results.
1.0 STEERING TRIM
SETTING THE STEERING TRIM
Use the external trim button located above the Steering Wheel to make ne adjustments while driving your
model. During assembly of a new model or a repair use the Sub Trim feature; see section 2.3 TRIM (SUB
TRIM), to center the servo. Use the external trim button for small adjustments when operating a model.
SETTING THE THROTTLE TRIM
Use the external trim button located under the Steering Wheel to make ne adjustments while driving your
model. During assembly of a new model or a repair, use the Sub Trim feature; see section 2.3 TRIM (SUB

2.0 MAIN SCREEN
After the VR3T 2.4 has performed a system check when turned on the MAIN SCREEN will appear. This
screen displays important information about the battery voltage, settings and the model selected.
Represents a fully charged battery. This will start at 11.0 or higher depending
on the type of AA battery that is being used to power the transmitter (Alkaline/
Rechargeable NIMH). NOTE: When the battery has dropped below 8.4v an
alarm will sound.
Displays the current Steering Dual Rate value (see 1.3 - ST D/R Steering Dual Rate)
Displays the TH HOLD status as ON or OFF
(See 2.4 SYSTEM/HOLD (TH. HOLD)
Displays the transmitting mode
(See 2.1 SYSTEM / MOD (MODULATION)
The current position of the steering and throttle trims setting are displayed.
PROGRAMMING MODE
To enter programming mode from the Main Screen press the ENTER button on the transmitter. To save and
exit from the sub menu press EXIT.
2.1 FUNCTION / EPA (END POINT ADJUSTMENT)
End Point Adjustment (EPA) - Used to set the maximum travel of the desired function from
0-120%. Can be used to set both directions of travel (fwd/bk & lft/rt) to adjust the overall
range of movement or value. Can be used in conjunction with Dual Rate (see also Dual
Rate)
1) Press ENTER to see the FUNCTION MENU
2) Use the +/- KEYS to highlight EPA and press
ENTER.
3) Press ENTER to select a value.
4) Use the +/- KEYS to change the value.
5) Press EXIT to save and return to FUNCTION
MENU, press EXIT again to return to the
Main Screen.
NOTE: When using an electronic speed control
(ESC) set the Throttle EPA values to 120%. This
will allow the ESC to calibrate itself to the VR3T
2.4 and make the response and feel of the throttle
ST D/R - Steering Dual Rate (ST D/R) - Creates two overall steering travel presets. Set
the primary value POS0 to an equal or lesser percentage of the steering EPA. Set the
secondary value POS1 to a lower percentage than the primary value POS0. Use the
ST D/R button on the grip of the transmitter to select between the two preset values.
Example, if the EPA steering value is 100% then set POS0 to 100% (or less) and set
POS1 to 70%. When the ST D/R button is pressed the steering travel value changes
between 100% and 70% This allows you to change the amount of steering while
driving.
1) Press ENTER to see the FUNCTION MENU.
2) Use the +/- KEYS to highlight D/R and press
ENTER.
3) Press ENTER to select a setting.
4) Use the +/- KEYS to change the value.
