One of the places I SFH from on the R44 charges 0.1 for start up and another 0.1 for shut down on top of the datcon time.
A rip off I know, but its handy to get to.
Another place I fly the 44 just charges on the datcon which for me is far better.
Any other people know of the 0.1 for start up and another 0.1 for shut down?
