Secondly I found the bike to be a bit wobbly, but I dont know if this is the norm as I have never ridden a one wheeled trailer before.
So it looks like its back to the drawingboard.

Looking at it again (sorry it took so long) I think there is indeed a flaw in your design - the hinge just in front of the box. My monowheel trailer, the Edinburgh Bicycle Company
Revolution Cargo is vertically rigid along its entire length, pivoting only at the attachment point, on the rear wheel axle. This means that the front wheel of the bike doesn't lift - the load is evenly supported by the rear wheel of the bike, and the trailer wheel. With your hinge that far back, there is a lot of leverage trying to pivot the bike about the rear wheel, and lift the front wheel.
Good luck finding a solution.
