A huge red flag for a crowdfunded project is any sort of new technology that needs to be developed before the project can be successful. Something that has never been done before might simply not be possible or might turn out to be impossible to resolve before everyone loses interest. The amount of money available makes no difference past a certain point. These hard/impossible problems can sometimes be hidden inside other apparently easy problems. This is particularly true if there is a significant software component.
