What's wrong with the Chippy brakes? They are far and away the best I have ever known in any aeroplane. With the free-castoring tailwheel you can spin the aeroplane around on the ground in its own length! They offer much finer control as a means of steering on the ground than any other I've tried.
But you do have to learn to use them if you are used to the 'car brakes' on a Spammy.
And what's this ring-pull engine stop? Mags off, throttle wide open was the way we did it!
