Spektrum and JR DSMX Transmitter Bulletin
DSMX transmitters operating in DSM2 mode
The Spektrum Team has been investigating sporadic
reports from DSMX transmitter owners using their
products in DSM2 mode. We have discovered that in some
rare instances, DSMX equipped transmitters with the
Product ID (PID) within this bulletin, may have a
backwards compatibility issue that could cause a "hold"
with the following superseded DSM2 receivers: AR500,
AR6100, AR6100E, AR6110, AR6110E, AR6200 and AR6300.
Note: This bulletin does not apply to DSM2 ONLY
transmitters.
If you have a DSMX transmitter with one of the following
PIDs, please complete the Transmitter Service Request
Form to receive a prepaid shipping label to send your
transmitter to Horizon Hobby for a free firmware update.

Form.
Horizon will pay for ground shipping within the United
States and Canada.
If you purchased your product outside the US and
Canada, contact your local retailer or distributor. A
list of International distributors may be found HERE.
If you have further questions in the United States,
please call Horizon Hobby Product Support at

Spektrum DX8 Gimbal Bulletin:
Spektrum Product Development has been investigating
reports from DX8 transmitter customers experiencing
servo movements inconsistent with corresponding
transmitter stick input.
As a precautionary measure, Horizon Hobby would like DX8
customers to perform the Monitor Test to examine Gimbal
controls over the entire range of each axis of input.
Expected results for the Monitor Test should show smooth
tracking with corresponding stick input. If the Monitor
"jumps", hesitates, or is seen in a channel other than
what is being tested, please follow the Monitor Test
instructions below to test DX8 Gimbal movement:
Monitor Test:
Step 1: Turn on power switch. Ensure left stick position
(throttle) is low and Flap/Gyro switch is in position 0
or all the way up.
Step 2: Press the roller to enter the Function List
menu.
Step 3: Using the roller, scroll to the bottom of the
Function List menu and depress roller to select Monitor
function.
Step 4: Note the position of the Aileron (AIL) and
Rudder (RUD) positions. Ensure all trims are centered
and sub-trims are zero before continuing to Step 5.
Step 5: Move the Throttle (Left side) and Elevator
(Right side) gimbals up and down being very careful not
to touch the control sticks. While moving the gimbals up
and down, note the AIL and RUD positions on the Monitor.
ONLY touch the Gimbal on the outer frame where shown,
being very careful not to move the stick as this will
falsify the test.
Step 6: If the percentage for the Aileron or Rudder
changes by more than 3%, follow the instructions for
sending your DX8 transmitter in for inspection.
