Thank you for all.
I am simulating Mission Planner along with SITL, but I have something problem with Radius on Loiter_Turns in Flight Planning. I found that even if I put 500 Radius and write to SITL, it doesn’t flight like that much distance. finally, I found that even though, I write 500 Radius to SITL, and if I read it from SITL, it is 244 Radius rather than 500.
If anyone knows about the matter here, advise me, please.
