Nice looking Tiger.
My partner and I installed an electric tow in our hanger from Aircraft Spruce for around $430. We tried 3 other models before we decided on one. We needed a long control cable as its a challenge to end up close to the hanger door after flying. Also, do your research on where to pull backwards from on the airplane (not the tail tie down). I would be glad to explain our whole system if your interested.
