We developed the fan pretty thoroughly during our build season. First we started by testing deflection using a standard pedestal fan. When we found that the used fan gave us e the deflection we wanted, we looked at the motor specs on that fan. From there, we matched those specs as close as possible. We also increased out fan blade from 3 prop to 5 prop.

Our fan is powered by a CIM going to 3:1 banebots reduction. We are able to displace 5400 cubic feet of air per minute. So just to clarify, our fan is not an off the shelf fan, but a custom prop mated to a banebots. The cage is COTS as well and makes it look like an off the shelf fan, but I assure you it isn't.

Also we have gone up against taller shooters and have done very well against them, our air current is focused through our wind sock which improves our deflection.
