The knife edge 45 turn is rather 'trick', but wait till you get to do the knife edge Stall Turn! But this is obviously destined for the Unlimited guys, power is required together with a more potent model. Advanced will, as I said, have a 'tamer' programme, sensibility!
I have been practising knife edge circuits and figure eights, so this should not prove too difficult, the tricky part is changing from the upline to down line while doing it. Have not tried that yet [&:]. Though I presume that this wont be in the advance class, I would suggest something knife edge somewhere.
The thing is, because there are 2 Freestyle rounds a pilot can take full advantage of these if it is preferable, cos 1 round will be dropped, (the lowest score obviously).
Cool, gives us a chance to try different approaches and see if it impresses the judges.
