Not yet...
We are working on the vectored thrust mount & expect to bench check it this week.
The vector thrust mount that is to be tested is truely amazing.
We will test the mount @ 3-5 degrees deflection then move up, so max pitch gives about 5 deg motor vector
If things go well... aircraft #2 will have vector thrust/canard/elelator/no spar


Aircraft #1 is a pig & will meet the dumpster soon but we still want to get some max canard throw data points.
3 to five deg. sounds like a good place to start, I have been trying to find out what a good place to start with vectored thrust myself.
I have tried to find out what others considered a good starting place for vectored thrust but have not seen much definitive. I figure the Osprey type uses 90 deg. of thrust but they are trying for helicopter type of performance. I am looking for a max of 45 deg deflection with an ultra stable (in pitch) shape of a forward swept delta. The glide test have worked well so now I am working on the deflectors for the ducted fan part.
Sounds like you have gotten some interesting results thus far.
I am curious about no spar, stressed skin?
