Beside the SS in pic is a SSE it has a tube that I used like Minn just described, if you look under it you can see it on ground, I fixed that by taping it to rudder so it wouldn't drag ground. I had the U-Can run threw a tube inside, but had glitches, which I think came from z bend on throttle (metal to metal) just didn't run it bk threw tube. I'm gonna change SS to inside just for looks
