I have a Revolution
Don't panic. This is simply misinformation and misunderstanding on your part. The Chinese MARKETING departments have no clue about how TECH works.
First, there is no such thing as a 'Revolution.' Those are two completely separate and distinct FCs. The MARKETING department puts those two words in the product description to gain hits.
Please point to the web page ad that you got the quad from.
Next, one thing you didn't know was that if you had a quad that flew, that before you 'did things' to it you should have saved the current configuration.
One way to fix that is to look at the quad web page and see if they have a downloadable *.uav file. If they do it still -may- not work because it'll have to be compatible with a specific version of the GCS, but it's worth a try.
