I am pretty sure you dont have any extra spots on the receiver. Just get the Y connector that was mentioned above and you will be fine. I had to do that one day when I switched to a FM radio due to 2.4GHz antenna broke some how. Good thing I had my LST2 with me. It comes with that Y connector for 2 servo's and it work perfect for my truggy that day. Hope you have the extra room in the radio box for the extra wiring.
