I was wondering if anyone knew the maximum rotor speeds for the IRIS quad copter? I wanted to find out the individual angular motor speeds based off of different PWM inputs. Any help getting to this point would be appreciated.

Hello all,I have had one accident with IRIS where I did not properly screw the nuts down, a wing flew off mid flight, and IRIS crashed. I since replaced the broken wing and had a few successful flights. However after a few short flights directly…

I have lost one of the washers that are used with the nut on IRIS's blades. Would it be safe to fly without this washer? If not, does anyone know what I could buy to replace it?
