Hi Barland.
To proctect the radio, it is a good idea to remove the crystal. You will notice a longer charge on your battery if you do this and it does help to protect your radio and also does not broadcast any RF output. The antenna does not need to be raised to use this with your software, but depending on the radio, it is a good idea to prevent overheating in your transmitter.
Use of the 6XAS with Realflight, will in no way harm your transmitter.
I hope you find this information helpful. Should you have any further questions or concerns, please do not hesitate to contact us at 217-398-8970 for Support, 217-398-0007 for Service or via fax at 217-398-7721 or by email at
