Helicopters

Wow that's a lot of helicopters.  Helicopters are an obvous choice for Technic since they often have open girder construction, just like Technic, and making things rotate is the core function of Technic.

They vary widely in size and style, but are fairly common in features with a couple of exceptions.  The first and oldest, 852, was the only one with collective pitch until 2013 when 9396 was released.  A couple of the others pitch the entire rotor blade, which is neat, but is not what real helicopters do.  8856 has lots of features and is probably the best overall brick built set, and 9396 is the best studless set (and the most scale accurate).  But for big first impressions, the 8485 Control Center is unbeatable.  I wore out so many batteries on this thing that I bought a transformer from Radio Shack and now have it plugged into electricity full time in my display.
