Those fans look really, really good. This project is off to a good start.
The original idea for this was to combine two AirGeeps in a side by side arrangement and have a drive-on-drive-off platform in between to hold a HMMWV size vehicle. The cockpits and passenger spaces would be covered over and the flight controls would be via a tethered controller in the front passenger seat of the vehicle being transported.
This first iteration is to figure out how to attach the fans inside the AirGeep and to determine what needs to be done with the fans that will not have the huge spinners on top blocking the view. The only way the spinners could be used is if this turns into a twin craft with platform in between.
I may have to order another set of fans.
