I received this from Redi Heli today:
Dear Valued Ready Heli Customer: We've recently been made aware of some safety concerns regarding the the Align Carbon Fiber Blades product # H60115. Ready Heli recommends that you STOP using these blades immediately. Due to our commitment to stand behind the products we sell, we would like to take this opportunity to offer a FREE exchange of the Align Carbon Fiber blades you have recently purchased from us. Please understand that this is an offer made by Ready Heli and not Align, Align USA or any other party. The manufacturer or distributor may or may not decide to replace, refund, or warranty these blades to you directly outside of our offer and accepting these replacements may void that opportunity via those channels. The blades you return will be replaced with RCP Carbon Fiber Blades in a size of your choosing (500, 550, 600 or 325). Please note this offer is good for 'un-crashed' pairs of blades only.
