He's not trolling you at all. He's simply saying that just because you, and the thousand other people like you, complaining won't get it done any faster.

Working ESC's or not, You sent them in for a FREE upgrade. The only money you came out of pocket for the upgrade was the cost of shipping. Hardly something to get upset about when you're basically getting the NEWEST model esc back after it's all said and done.

To refresh your memory, I sent in four (4) BRAND NEW speedo's that were all used ONCE. You could always do what I did and buy some other esc's to get you buy until yours come back?
