Hey, this mustang hobby is making me so looney I have had a question about open rear on my mind for a week now and its driving me nuts. Ok , heres the question-- If an open rear oly delivers power from the right tire in the back, how come the car doesnt shoot to the left on acceleration, instead of going straight like it does. I mean, like say a shoe is closer to the drum than the other, and it will pull to the other side. How does an open rear stay straight????????? Somebody answer this and let me finally rest!! Im loosing my freakin mind! Thanks.
