Hi Andrew, if you have the RoboMaster TT drone then I highly encourage you to check out the mission pad support in the DroneBlocks desktop app:
It’s one of my favorite features to play around with and gives improved flight accuracy. You could program the RMTT to perform a specific action at each pad or even display the pad ID on the LED matrix. Or you could have it do X number of flips depending on which pad it sees. Doing flips is always a crowd pleaser 
You can even go into full screen video mode and manually fly RMTT around the room. Lots of possibilities and I’m sure you demo will be a hit. Feel free to post any questions or idea here and we’ll be sure to follow up. Good luck and keep us posted!
