HWD,
I hope you dont mind me giving you a tip about take off in an AA5.
As they are not the type to just leap into the air any use of brakes will prolong the t/o run.
Just start on the left of the runway, point the aircraft slightly to the right of centerline (only if your on a wide runway) and you will have rudder control by the time you are pointing down the runway. This can also be used also it there is a crosswind from your left, just point a bit further to the right
