Short answer is yes. Take off carts/catapults have been built and used with limited success but they pretty well turned into a cluster to use. Unless you have a disability that would prevent hand launching, I would stay away from the cart idea.

With that airplane and a .46, use a low pitch prop to start, and give her a hand launch. As others have said have someone else do it for the first time or two till you get used to it.
A good starting stand is a must.
