certainly it would help...maybe you can also help on the weight of the airplane itself, using lipos and trying the hover at the end of the flight, when the plane has burnt most of the fuel.

Had seen the J-10 from Carf, wich hovers pretty well.. the plane is very light, and the landing gear legs are made of CF, maybe you can do something like this too. It also used at first 5 gyros (!) but now is using just one I-gyro unit wich is better and also lighter too.

Not the same plane, but this is a video of a J-10 using gyros for hovering somewhere in Asia..
