I wanted to separate the H135 into its own thread. If you are missing having a helicopter this freeware might solve your need. The developers are doing almost daily updates and are willing to put the work into developing this as far as possible.

The current release version is v0.79. The video is a tutorial and reflects the functions of this version.
