chevelledude33, I have traveled a ton with my equipment without to many problems. Everytime that I have to check in my stuff they end up riping my Losi bag all apart looking at everything that is inside. The most common thing that they look at with me is my power supply and chargers. Other than that you should be okay. If you are going to carry anything onto the plane, be sure to bring a Car Action or some magazine RC related so they don't freak out. Last week I carried on my transmiter without any problems, but that could have just been my lucky day.
I hate to say it but some airports do not allow you to lock your bags. If you do they can and do cut locks on locked bags to inspect them.
Personally I think it's leaving them more than open for a major lawsuit inspecting your bags without you being present. I know when I traveled out of Seattle last June I was required to leave my overstuffed bags unlocked and I found deep down inside a not stating that my bags had been searched. Just an FYI for you guys wanting to lock them in your checked baggage.
Sorry for the bad info then. I haven't been on a plane since my honeymoon, well before September 11th.
I had locks on all my luggage. I guess for security reasons now, they have to be able to gain access.
Leaving out of Virginia, Baltimore, DC, Miami and a few other places they never said a thing about locked bags however they did a quick search while we were waiting in line.
