Steve, how are you driving the extra 4 motors? Parallel pairs from onboard motor drivers, or you have extra ESCs and all that?
Thanks,

Well with both motors on one arm out it is the same as a quad with one out. I could show you a number of video's in testruns for Srinath that all failed. Only one attempt with heavy code changes did stay in the air for a couple of seconds

We have been trying to get the 'quad' or in this config the x8 to get it yawing so fast the thrust loss would be compensated. Well, it could work on a small and cheating way with some balance shift, but practically.. no (well, I couldn't anyway).
@Steve, that is a great idea for getting props close together. A couple of years ago I did see an attempt from Hacker motors in the time that brushless was not that powerful to stack two motors with one motor having a hollow shaft, where the bottom motor shaft was running through.
With pancake motors it could be done. Only the bearings must be very tough because the stacked props could create quite a nasty shake.
