Last week on Facebook I noticed a post from DJI stating there was a firmware update for the Spark. One of the updates was improved transmission on 2.4GHZ. I went to update the Spark but the update wasn't there! Since then it appears the FB post has been removed.
I guess DJI are tinkering with the release but hopefully there's going to be a fix for dodgy image transmission in CE areas?!
