Actually, 150 for the complete set is a steal of a deal - this is not a toy grade product, 900Mhz radios and Lithium Polymer cells that are ultra lightweight - I have had a Micro Butterfly for some time and you cant break it - It just doesn't weigh enough to damage itself.

I'm glad I found this post, They just released a 5 inch spitfire too...
