Just thought I would share that I just went on a flight and brought my entire ultimate with (2) 2s lipo batteries, TX with battery removed, lipo battery charger in my carry on bag. Didn't even get searched although the security guy with the X-ray computer really spent some time on it. I did pack the body in my checked bag. Was the first time using paddle tires. Paddle tires are very impressive in the sand! I will post some pictures later.
