Boiling the STOCK blades for 3-minutes will straighten every warped blade no matter how bad it is. I'm supplying blades for four (friends & family) CX2's and have purchased 16-packages (still 10-packs un-used) since Christmas. I have found some pretty badly warped blades out of these 64-blades and I have not found a single blade that did not return to perfectly flat around the edges (when laid on a flat surface) after boiling.

I am now boiling every blade from every package then weighing each blade, and then matching sets of blades. Sets that don't match (by weight) perfectly get balanced and each set is kept seperate from other sets. If (when) we need to replace blades it's now easy as we just grab a matched set and replace them. The heli's tune stays the same (or very close) and we are back to flying in no time[8D]

DO NOT BOIL XTREME BLADES! Xteme blades will curl and be ruined if boiled!
