As far as the knife edge goes. I fly a 40 size and a 56 Satio. With that engine swinging a 12x6 prop on high rates (all the throw it's got) I can stay level in a knife edge until the next state at full power and rolling into the KE at a slightly upward angle. Anything less and it will slowly lose altitude.

When my OS46AX was in there and turning an APC 11x7, If I built enough speed and be on high rates I could start the KE level and stay that way for a little while until it starting losing altitude. If I started at an upward angle the KE would go longer but still fall out.

I have seen and heard other people add 1" to the top of the rudder on both the 40 and 60 and then it would KE all day long.

Nice job on landing with only one wheel. Tough planes these 4 star's (4*). The worst I ever did was plant mine in the high grass next to the runway because it was getting too dark and I lost my deapth perception. All that happened is I tore the main gear out as clean as could be. 30 minute epoxy and overnight drying and I was flying it the next day.
