A helmet mounted HUD would be the best.  $$$  IMO Helicopter flying requires moving your scan around much more than our fixed wing counterparts and automobile applications.

Hi @Tim Morris I disagree, with military aviation I can see the helmet HUD being a big advantage, but for recreational flying I would prefer to look outside as much as possible so with critical data on display all the time in one spot on the windscreen then I get to enjoy the passing scenery without compromising safety, or flight awareness, and the HUD will be displayed inside the windscreen so not affected by rain and to be serious, if you are flying in rain, better check the erosion on the blades
