Hi, I am develop a VTOL and I am having difficulty getting SITL and Realflight 9.5S to work reliably together on my PC laptop. I am using a new Intel Core i7 PC laptop and I have been testing several existing SITL models on Gethub: Convergence, Griffin, and Altitransition. I have been able to get each one of these to fly well, in addition to the VTOL I am developing, using the Tactic USB transmitter that comes with Realflight.
But I have noticed that I am having trouble getting the models to Arm reliably, via the Data/Actions folder, but I am able to successfully connect Mavlink, via the Simulaton folder. When this happens, I have noted there is a large red X over the clock in the top right hand part of the horizon indicator window. When this happens, I have tried restarting both programs and even the PC. Sometimes this works, and once the vehicle is flying, it seems stable. But if I close the programs and try them again it can fail. I am using Mission Planner 1.3.79 build 1.3.8375.24878 Arduplane V4.40dev (441a2ee0). The above models I have been testing are found below on gethub:
I have been using the instructions on how to install and use SITL on Ardupilot:
Has anyone else had this problem, and did you find a fix?
