The Cub might be a bit of a handful as a second plane. (If it's anything like most Cubs.)

It will be considerably harder to take off in particular. Especially because you haven't flown a tail dragger yet. Cubs require diligent rudder control when taking off, and often require a touch of down elevator as they leave the ground. They also require rudder input when turning. (Mine requires opposite aileron when turning due to adverse roll coupling.)

Not trying to discourage you, just trying to get you to buy that Stick first!

But everything I said is true.
