With the brand new Walkera QR X400 it is all about the looks.  Well, performance too, of course.  OK, let's add an extra dose of ruggedness, too.  The QR X400 merges the performance characteristics of the MX400S with a whole new sleek and modern look while increasing durability and decreasing the likelihood of breaking parts when we fly into stuff.  (Come on, admit it.  We all fly into stuff:  walls, ceilings, trees, dogs, wives, etc.) Take a look at the beefy landing skids on this baby.  Mr. Harley (my 90lb Golden Retriever) can actually sit (gently) on this one without smashing it.

Still want to take photographs and videos?  No problem.  The QR X400 can tackle that assignment just fine.  It may not have quite the stability of the regular MX400 with its 3-bladed prop, but then again, there is nothing like a FPV of doing a flip or a barrel roll.

So you've spent all evening trying to decide which MX400 is the right one for you.  Let's take a look at the specs and features:

One last note:  If you have seen this item elsewhere at a lower price make sure they 1) are a factory authorized Walkera dealer [most are not] and 2) include a genuine Walkera LiPo and charger, not some cheap knock-offs sourced elsewhere.  Walkera Helicopter Supply provides only official Walkera parts in our packages.
