Works awesome for the EXO 2 chassis and others. You need HPI Ti antenna kit Part number Z154 and a 3mm nut.
I shaved about 7-8 inches of protective covering off of my antenna. I wrapped the raw antenna wire around Ti antenna, then I take the remainder and wrap it like the instructions says around the provided board. Then I take some clear heat shrink (you chose your color here) and I cut it to fit then heat it up snug around the antenna. I walked down my street until I could not see the micro anymore (blocks) and I was turning the wheels while my girl friend was watching and reception was great.
Here is the finished product
