To bad they don't do a better job of keeping stuff in stock, I bet they lose a lot of sales because they don't keep more in stock, Most people do not want to wait and if they do choose to wait some sort of a time frame would be nice. If I choose to order the combo I want who knows when I get it and I want to order another battery as well. but battery will not ship till all back order items are in stock. and if I order motor and battery now and wait on ESC it will cost me 2x's shipping plus is 20$ more expensive. However I can order a comparable system that is in stock and have it in a few days, for less than 20$ more, over ordering it separate. Guess it all depends on how impatient I am..........LOL
