Used the RTH feature for the first time (twice) today. A message on the controller appeared "aircraft is returning to home. Minimum RTH altitude is set to 98 ft. You can reset RTH altitude in Remote Controller Settings after cancelling RTH." Don't want to reset the altitude. Not sure why I got the message. Each flight altitude was well over 100’. Did I accidentally touch a button or move one of the sticks during the process or is this a normal message? I am still very new to this and still learning.
