Weeeeeird I think I fixed it. Once I push end, it locks up kind of. But once I push BOTH arrow buttons at the same time it goes back to normal. Now I have other problems:
Every time I plug in my Explorer2 to my Futaba receiver, along with my futaba standard servo the ESC doesnt respond and it doesnt steer. But if I just plug in the esc and no servo it works fine (no steering). I tried a different servo and it works fine ( another futaba servo from another car). How can I fix this, I dont want to have to buy another servo!
