Yes, I agree. The only day I have gotten this warning is day one when I was launching off of grass at a football field. I stopped launching in that manner and haven't received that warning since. I have launched off of a picnic table & a large flat tree stump with no issues since that time.
I have had several gimbal warning messages. I agree with the grass issue and use a large launch pad if the grass could contact the gimbal. But I've also had this warning while in flight, after a satisfactory take-off. Shutting everything down and starting up again appears to address the problem. Is there any other issue about seemingly random gimbal issues that people have experienced. (The drone has not been damaged and no hard landings.)
In addition to often using a landing pad in fields where grass might be wet or long, or there is a lot of dirt, I sometimes use snap-on legs for my Spark. I learned through experience that each type of leg has a different application, so I wanted to share this.
The first photo I am attaching is of the legs that snap onto the propeller arms. These are heavier than the other set. However, it is not possible to use the propeller guards with these legs. I use these for outdoor flying on rough ground because they are stable.
The second photo is of the legs that snap onto the battery case. This attachment is lighter than the other legs, and it allows the use of the propeller guards. I use these only indoors with the prop guards. These are not stable for uneven outdoor ground and the drone might tip over if these are used outdoors.

Sorry about the blurry images. I hadn't noticed that my cell phone camera focused on the house across the street and not on the drone.
