Mizzy..not bad at all...really...just a few things
first add way more Power!!..really slam the throttle forward to full power right from the start (it is a german engine..it can handle that:))
then look what the plane does..do not add right rudder from the very start..just look what the plane does and then react and compensate
I recommend not to lock the tail wheel right from the very beginning, because at slow tempo the rudders are to weak to fight the locked tail wheel. As I said earlier wait 5-7 seconds before locking the wheel (then the rudders have enought power)
It is really all about whatching the plane and reacting..what does it do..where it wants to go..
