Hi fellow quadplane flyers and devs.
Today we tested the behavior of quadplane whilst armed on the ground. When it is switched to RTL the quadplane will instantly try to takeoff at full throttle. As mentioned previously on other threads, this is the same behavior it has in SITL as well, so I held down the quadplane safely in expectation of this.
I think this is quite dangerous as any cycling through the modes on the RC will launch the aircraft if it is armed. Especially larger quadplanes this could lead to very dangerous scenarios, where the pilot or others are still to close to the airframe prior to launch, or where the wrong mode is selected inadvertently. (eg some RC swtiches cycle thru)
For safety reasons the only mode that should really trigger takeoff is Auto. RTL is typically only used to get the aircraft to return to launch, but not to takeoff. Also I'm thinking that the current 6 modes available for selection should be expanded so that both Q and plane modes are available at the same time to allow for either quad or plane mode recovery by the pilot.
On a unrelated matter, we are also experiencing intermittent attitude control issues in qloiter, qhover and RTL, which cost us one of our test air-frames today. After a unspecified time the aircraft will pitch forward sharply without warning. the crash occurred after switching from auto to RTL.
