As light as the plane is, and with its long tail moment, it will weathervane very easily if you're taking off in a crosswind, plus it does what all tail draggers do when you hit the throttle--turn left if you don't counter with right rudder. It's probably the most difficult plane I have to keep straight on take-off; I practice with it for that reason.
You might want to play with the landing gear and bend the axles to toe in the wheels a little; just enough to notice they're not parallel, a couple of degrees. Toe -in makes the plane want to self correct its straight ahead roll.
