The Black Hawk RC Flyers of Cedar Rapids Iowa put on an indoor fly in at the UNI Dome each winter. It is billed as the largest indoor fly in of the Mid West. The UNI Dome is a great venue for this type of fly in as there is ample space and a high ceiling at 162 feet with few obstructions. The air is calm and the temperature is a warm relief in what is normally the dead of winter in the midwest.
