About the Mission Planner SITL with Realflight8

The SITL in Mission Planner is very useful. But now I face a problem that once I choose the float plane(water plane) in Realflight8, then use flightaxis sim mode to connect RF8, Realflight will crash. I want to know what happend. Can FlightAxis support float plane in RF8?
Thanks!

@Michael_Oborne

you will need to direct your question at realflight support. given that others work, it is a bug in realflight that is the problem.
