I believe it is. However if you've lost an engine, I don't think that you're too concerned with ground clearance any more...
I'd be curious to know if it could continue single engine flight (in airplane mode) for an extended period of time (such as if you lost one over hostile territory.) Seems like the yaw with such a large "prop" out there would be difficult to over come, but it does have two rudders.
