READ THIS FIRST: There is no longer any reason to use the LaForge FW in these modules. Look for GC9N firmware instead here (https://goo.gl/tjBkFH) or in this RCGroups Thread (http://goo.gl/kIHt8D). It has far more options and works better.
[[WARNING]]
You may brick your RealAcc when uploading a new firmware. So make sure you know what you doing before performing this.
Remenber to ALWAYS clean the EEPROM before loading the LaForge v1.6 in he module, fail to do so will make it not work.
This was done using a older version of v1.6, the new v1.6 may have been altered to prevent it from working in other modules other than the LaForge.
