Same here. I don't have a flop tube. So the fuel gets pushed to the outside which makes the engine quit after a couple of seconds and the prop will stop shortly thereafter. Happens every time. See:

If I counted correctly prop stopped after about 9 turns engine quits a bit sooner then that in that video which is actually surprisingly long considering that the fuel gets pushed outside pretty much right away. So there is quite a bit of fuel in the system.
The only problem with that is that you have to keep the downline after recovery for a while longer before the prop starts spinning again (starts spinning at about 160mph). So the recovery took about 2000 feet compared to a couple hundred feed after a 3 turn spin. Partially due to the recovery taking longer (2 turns or so) but partially also due to keeping the downline a bit longer . Something to keep in mind in case you try.
As for glass. Yes my Dynon starts tumbling after a small number of turns and recovers in a couple of seconds after leveled. Interestingly my GPS (GPS2020) gives up after 20 or so turns. Now I specifically put my GPS in the wing tip so it works during acro and I can go through the sports man routine without loosing GPS coverage or accuracy. So it's not an issue of line of sight. So not sure why that happens. Hope I don't have a loose connector or something... .
