Spektrum DX6i SPM6630 用户手册

SPEKTRUM DX6i • RADIO INSTRUCTION MANUAL

In airplanes, install the main receiver in the servo tray in the cen-
ter of the fuselage. Install the remote receiver in the servo tray 
by the side of the fuselage or in the turtle deck (space behind 
the canopy and in front of the vertical stabilizer). 

In helicopters, install receivers in the servo tray, where there 
is usually sufficient room for receiver separation. Where there 
is not sufficient room, install a receiver on an external receiver 
mount made of clear plastic.
Note: The DSMX DX6i is compatible with all current Spektrum 
DSM2 and DSMX aircraft receivers, but NOT compatible with the 
original DSM AR6000 receiver.

CAUTION: When using the DSMX DX6i with parkflyer 
receivers (the AR6100, AR6110, and AR6115), it’s 

imperative that these receivers only be flown in parkflyer-type 
aircraft (small electric airplanes or mini and micro helicopters). 
Flying receivers designed for parkflyers in larger aircraft could 
cause loss of connection.

Due to vibration, install servos using rubber grommets and 
bushings in gas- and glow-powered models. 

Do not over-tighten mounting screws. 
Install servos using servo tape and glue in electric and non-
powered aircraft. See model instructions for installing servo(s)  
in your model. 

Do NOT lubricate servo gears or motors.

Do NOT overload retract servos during retracted or extended 
conditions. 

Always make sure servo arms and linkages can move freely over 
the whole path of their intended travel. A blocked servo linkage 
or servo arm can cause a servo to draw too much current so a 
battery charge is quickly drained. 

Always correct control surface vibration, such as “buzz” or “flut-
ter.” Vibration can destroy feedback potentiometers in servos. 

Always install servos using rubber grommets and brass eyelets. 
Do NOT over-tighten servo mounting screws. Doing so inhibits 
the screws from dampening vibration. 

Always make sure a servo arm is fully attached to the servo. Use 
only supplied servo arm screws. Use of other sizes of screws or 
screws from other manufacturers can result in damage to the 
servo.

Always remove and discard “yellowed” or otherwise discolored 
servo arms. Discoloration shows material may be brittle and can 
break at any time, possibly causing an aircraft crash.

Always make sure model screws and linkages are tight. Vibration 
loosens screws and linkages so that damage can result. 

Set up and operate a model so power to the receiver is NEVER 
interrupted while flying. This is especially critical on giant-scale 
models that use several high-torque or high-current servos. 
Power systems unable to provide minimum receiver voltage 
in flight are the number-one cause of in-flight failures. Some 

components that cause a receiver to have too little power supply 
include: 

•  Receiver battery (number of cells, capacity, cell type, state of 

charge)

•  Switch harness
•  Battery leads
•  Regulator (where used), 
•  Power bus (where used)

While a Spektrum receiver’s minimum operational voltage is 
3.5 volts, test your model to a minimum acceptable voltage of 
4.8 volts during ground testing. This battery charge capacity 
compensates for discharge during flight or for flight loads  larger 
than ground test loads.

CAUTION: We recommend that you DO NOT fly a model 
with battery charges at less than 5.3-volts.

1. When setting up a large or complex aircraft with multiple 

high-torque servos, use a current and voltmeter (Hangar 9 
HAN172). Connect the volt-meter in an open channel port in 
the receiver. With the system powered on, load the control 
surfaces (apply pressure with your hand) while monitoring 
voltage at the receiver. The voltage must remain above 4.8 
volts when all servos are heavily loaded.

Note: The optional Spektrum Flight Log (SPM9540) has a 
built-in voltmeter for doing this test. The Flight Log is compat-
ible with Spektrum receivers SPMAR9010, SPMAR9110 and 
SPMAR7010 (AR7000).

2. With the current meter connected in line with the receiver 

battery lead, load control surfaces (apply pressure with your 
hand) while monitoring the current. The maximum continu-
ous current for a single heavy-duty servo/battery lead must 
be no more than 3 amps, while short-duration current spikes 
of up to 5 amps are acceptable. When your system draws 
more than 3 amps continuous or 5 amps for short durations, 
use multiple packs with multiple switches and multiple leads 
connected to the receiver.

Note: The Flight Log cannot measure current draw (amps). 
When the Flight Log is used to measure voltage, also use the 
HAN172 current meter to measure the current draw of the 
servos. 

3. When using a voltage regulator, do the tests for 5 minutes or 

more. Current passing through a regulator generates heat. 
Resistance increases, causing heat to increase (thermal 
runaway). While a regulator may provide adequate power for 
a short time, test for longer to make sure it can keep voltage 
consistent at significant power levels.

4. Use multiple battery packs with multiple switch harnesses 

on large aircraft or complex models (for example, airplanes 
35% and larger or jets). In many cases, commercially avail-
able power boxes or busses must be used. No matter what 
power systems are used, always do a test (described above) 
to make sure the receiver is supplied with 4.8 volts or more 
under all conditions.

5. Peak detection fast chargers may show a false full charge on 

NiMH batteries. We recommend use of a charger that shows 
an NiMH battery’s total charge capacity. Make sure NiMH 
battery packs are fully charged when using any charger.
