I second the week landing gear.  I also second that a CX2 is too big for a house.  I learned to fly mine at work (in a shop) with 20' ceilings in a 50' X 100' area.  It had a hoist/landing pad in one corner.  I would not fly it in anything smaller as you could not do anything with it.  When the furnace kicked on it would blow it around.<div>
</div><div>If you want to fly indoors, and you do because there is no wind, go for the mCX.  It is 1/4 the size and only need's 1/4 the room.  So a 20' X 20' is more then enough to learn.</div>
