Yup, the one condition that I didn't test but should have is the Dual tail motor with one failed. After all with two motors you have twice the chance of a failure on any given flight [&o]
I suspect the draw would go way up and might hurt the 3-in-1 (or blow the fuse).
But at least you should be able to choose your crash location.
I will test this when I have a chance--watch the thread.
