This is absolutely awesome!!!!
Yes, it is welcome in the twins forum and I am sure all of us are pulling for your success.
I noted that you said use a gyro on the "Other engine".When I did my experiments, and the post is "Hovering with a twin", I think in page two now. The gyro I used was for two channel ailerons, except here I used it for the two channels to the throttles that were slaved together. It really did help. The problem I was trying to aid, was that with a conventional single tail plane, there was not enough prop blast for the rudder to work, and using the gyro on the two engines really did help. Completely successful for hands free hover, no. It is possible to keep the gryo on for normal take off. I used the hobbico aero for my experiments.
Please keep us posted.
Good Luck.!!!!!!1
