Re: For those who are skeptical about propellers - Team 2526

I hope you appreciate that the comments and concerns about the safety of your propellers is HELP from the CD community. I know several teams have given this approach serious consideration (including our team).

Team 980 chose an alternative drive concept, not because of safety concerns with fans, but for performance needs to support our game strategy. We felt we could contain a failed propeller and avoid having debris getting sucked in and becoming a dangerous projectile by using a "ducted fan" approach with steel mesh over the ends. I don't think your robot can detect a problem with your props and react fast enough to insure no shrapnel will be produced. It's better to have a design which is not going to allow anything dangerous to escape. With the ducted fan, you'll get better thrust performance as well.

I look forward to seeing videos of your robot on the move!
