DX7 and RL10

[Zman39]

I was wondering if anyone has setup the CSM RL10 on the DX7 and if so how did you go about it?


Thanks

looks pretty straight forward.

Zman,
I am guessing you want to use the remote mode and have more than one speed. You will probably have to use a Pmix from Channel 7 and mix it to the idle up switch.

If you want to use Manual mode and only run one speed. Then just simply set up the speed on the RL10 and go from there. Be sure to set your Throttle to Failsafe to Idle. So the RL 10 will go to idle failsafe in case of a problem.

Thanks David,
Ideally I would like to have it off in normal, one head speed in idle 1 and a higher head speed in idle 2. This was easily accomplished with the
9c gov menu but havent figured it out for the DX7.

Thanks
Mike

perhaps I misread but I thought only the RL had remote capability? :dontknow

From these instructions
http://www.rcmodels.org/csm/RevLockManual.pdf

Target RPM setting in 'Manual' mode.
If the RevLock unit is not connected to a remote channel, the 'Manual' LED will be ON and only one target RPM value can be set. To set
this RPM proceed as follows:-
Put the throttle to idle.
Ensure that the "Sensor OK" LED is on (see sensor test above).
Pressing 'SET' will cycle the unit through the five speed range options. The currently selected speed range will be indicated on the Speed
LEDs as illustrated below. If no Speed LED is lit then the unit is in Range 0 and is inactive.


Press 'SET' until the required RPM range is indicated.
Put the throttle to fully open.
Observe that the "ARMED" LED comes on.
The function of the Speed LEDs now changes to show the RPM Offset. The offset is how far the target RPM is above the bottom of the
range. In displaying the offset the LEDS have the following values:-
250 rpm
500rpm
1,000rpm
2,000rpm
Turn the ADJUST control clockwise to increase the offset RPM and anticlockwise to decrease it. To set the adjuster to the right RPM
either add up the value of each LED lit or refer to the RPM selector chart on the 'At a glance' card for the required light pattern.
Example:-
If you wish to set the target RPM to 15,500 rpm you should set the throttle to Idle and press 'SET' till the 14k+ (14,000 to 18,000) range
LED is lit like this:-
The required rpm of 15,500 is 1,500 rpm above the bottom of the selected range (i.e. the offset is 1500). You set this by raising the throttle
to full and rotating the ADJUST control until the 1,000 and 500 LEDs are lit like this:-



Target RPM setting in 'Remote' mode.
In the 'Remote' mode an auxiliary channel is used to control the target RPM. This should be a switch controlled channel with ATV
adjustment of the throw in both positions. RevLock allocates independent RPM ranges to the two switch positions as illustrated below.
100% 0% 100%

15% 15%

range
Set the two target RPM values as follows:-
Power up the radio. Go through the Sensor test or abort the test as described before.
Put the throttle to idle.
The unit will turn on either the Mode A or Mode B LED. Move the switch of the Mode/Speed channel between its two positions and check
that the Mode LEDs change. Make a note of which switch position corresponds to which mode.
With the switch in the Mode A position and the throttle at the Idle position press 'SET'. This will increment the Mode A RPM Range
which will be shown on the Speed LEDs. Note that Range 0 (no LEDs on) ensures that the unit will be inactive in that mode.
Put the throttle to full.
Set the RPM channel switch to Mode A
Setting the RPM offset for Mode A is done using the ATV of the Mode/Speed channel. The resulting offset into the range will be
displayed on the speed LEDs. Increasing the ATV will increase the RPM and vice versa. Start with a low ATV value increase the ATV
until the Speed LEDs just show the correct pattern for the speed required. The RPM selector chart on the 'At a Glance' card shows the
display pattern for all engine RPM values. Although the display only shows engine RPM in 250 RPM steps RevLock measures the Remote
channel value to an accuracy of about 6rpm and typically a 1% change in Remote channel ATV corresponds to about a 50 RPM change in
target engine RPM.
Switch to Mode B, put the throttle to idle and set the desired RPM range for mode B using 'SET'. Then put the throttle to full and set the
RPM offset for the mode B target speed.
Setting the ATV for either Mode below 10% will inhibit the unit from engaging. The unit shows that the ATV is in this state by flashing
the Mode LED.
Fine tuning of the target RPM can be made in flight by changing the Remote channel ATV or by mixing other inputs into the Remote
channel (see also Appendix 2).
Note that the Range is locked once the engine RPM reach about 3500rpm.
Where the Remote channel for the governor is controlled by the Idle-up switch (for example when using the JR code 44 feature) you may
be unable to reduce the throttle to the low position to set the range for either Mode A or Mode B. In this case select idle up and then press
'SET'. This will switch the display briefly to show the current range value (the 'Armed' LED will go off to show the change in display
mode). While the range is being displayed in this way further pressing of 'SET' will change the range for the current Mode. After a short
pause the display will revert to the offset value and the Armed LED will come on again.

Well I set it up on the idle up switch and have values set for idel1 and 2 but it is also engaging in normal which I dont want. ANy ideas?

Thanks

If I understand the instructions correctly you can not do what your wanting to do.
You can have 2 speeds set up , which is what you have in idle 1 and idle2. That is two of the speeds. Since normal is still a flight condition it is also using one of those speeds. I believe you can have 1 speed in Normal mode and another speed in idle up mode.
At least from reading the instructions that is how I understand them.

If you want to do it the way you have set up. I would think you would need a switch to turn off the governor in Normal mode.
