to replace

yes, this is the module you need.
Be sure current module still powered by is own regulator before module replacement.

Good morning, thanks for the answer
Okay the power came back
but the range is 50-60 meters
It is speculated that the (Revo RF module)receiver suffered damage
Oh my English is not good
Thanks

Range was better than 50m before the antenna issue ?
-
Yes up to 150 - 200 meters I did not have a problem, only control.
Now at 50 - 60 meters goes FS
Besides this it makes quick calls when it is at 50-60 meters
No signal goes fs
Yes signal goes to my own mode
Many times and quickly until it becomes crazy and flies uncontrollably

Not sure replacing the module give you the normal range.
Double check connections and antennas. Culprit side can be from Revo, oplink or both.
Some Oplink have shorts or almost shorts, take a look here:

Also make sure your transmit power settings are what you think they are.
- Plug in GCS OpLink into USB and check it and set it with aircraft switched off.
- Plug Revo into USB (with GCS OpLink disconnected) and check it and set it with USB only.
There is a bug in 16.09. You cannot change Revo RF settings via RF (don't use OpLink connected to GCS to do this). Revo RF settings must be changed via USB only. If you export Revo settings via RF, you will be saving the GCS OpLink settings as part of the save file. This means that File->ImportUavSettings and File->ExportUavSettings have problems when done via RF.
Simple rules to avoid problems: Always use just USB when making any RF settings changes. Always use just USB when doing File->ImportUavSettings or File->ExportUavSettings. Before someone complains about this statement, of course you can do these things if you understand what they do, but using these simple rules will avoid you needing to understand exactly what is going wrong.
