i have done all the programing using mission planner. it is supported.

By support we mean: it might sometimes, somewhat work. But it will not be reliable and some things will never work.

Did you read the link? It’s not supported. “it might work” doesn’t mean it’s supported by Ardupilot. Contact Radiolink for support.
The version of Arducopter that’s on there is not an official version. There was never a V4.3.7.6 and the V4.3.x official version is old.
