Thanks guys. I appreciate the reply. I tried to remove the stock antenna and while it unscrews, I couldn't pull it out very easily. There must be some sort of seal or gasket in there that it was hanging up on. Frankly, I don't mind the stock antenna. It would have been cool if Futaba would have offered a 3PKS with the FASST module already installed, and then the case could have been built from the get go without the telescoping antenna and mast, but I'm still happy to have my new radio system.

Can't wait to try it out. Just need to figure out which truck it's going into first and which digital servos I'll buy.
