RE: Dumb question
Yep - just run it to the outside.
As Chip said - most will run a line down the landing gear be careful when you do that you don't pinch off the line with the tie wraps.
Also you mentioned that you are new to 4 strokes. If this is a new engine beware that the GA100 Saitos vibrate - A LOT - especially when they are being run in on the rich settings. Because of the vibration issue on that model, I won't buy any more of that particular model now that the 1.25's are out. Once they are run in and tuned properly they are not too bad but they do still tend to vibrate a bit more than some other engines. The last 2 that I have bought I have done all of the run-in on the bench so as not to shake the airframe apart. (With most engines I normally do the last bit of the run-in on the airframe as a test of the electronics).
