You mean those rubber bands resting peacefully in the groove waiting for the thread to burn through so they can EASILY deploy the blades. Yes, I see that.

Anyone who decides to purchase and build on of these please simply follow the directions. I've never NOT had a blade deploy. The design gives the rubber bands a ton of leverage to deploy the blades. I used this same hinge mechanism on the F Helicopter model I flew at NSL last year.
