Purity: Crystal Blocks (#2) Helicopter Review

It's Wednesday and on to review number two.

Box.  I paid $4.99, for a $0.16 Price per Piece.

Instructions.

Parts.  Plates, Tiles, Propellers, Ball Joint Plates, Cheese Graters, Grille Tile, Slope, Brick, Pin Tile, 2x2 Studless Slope,
Axle Plate, and Inverted Slope.

Build.  2Rh+d8 Frame.

  

The Questions:

Can you build something -- a frame, station, or starship -- right away?  Yes.  (+5)
Is it below, at, or above the golden ratio?  Below.  (-10)  (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away?  Yes.  (+5)
Does it have more than a handful of immediately useful parts?  No.  (-5)
Score: -5 (B-).  A surprising amount of Ball Joint Plates in this set.
