I got mine at the local RC hobby shop. Just let them know what you're wanting to do (that's what I did) and they will give you the right rods.
The ones I got cost about $4 and came as a pair. Little steel rod inside a plastic sleeve and about 30" long.
Basically, you want the lightest ones you can get because the SkyFly isn't exactly a C130.

I ran mine on the outside of the tailshaft and used some clear packing tape to hold them in place.
I'm sure there is a prettier way of doing it, but I was improvising and wasn't sure how well it would work.
You'll need to cut a small hole in the back of the fuse to run them through... just watch the prop clearance.

Good luck!
