I am a ways off before my skills are good enough to approach an "actual" or "real" interest in this, by this I mean "ready to buy". I have been around these boards for a long while as with several other forums. I guess I am one of the "idiots", as some describe, that always want bigger, bigger, bigger! I am curious as to why there are no large scale EDFs, by this I mean 10-30lbs aircraft. If we have electric helicopters with 3 meter rotor diameters, 40% electric planes, etc, why is it we only have 45" EDF jets? I can't seem to find anything greater than 90mm which from looking around doesn't seem to push a whole hell of a lot of weight.

Is the issue that once you get the fans large enough to be used for larger jets that all of a sudden your motor/fan/batteries now outway the application? Are they just not efficient enough? Has no one bothered to care and build one that big? Just curious. Of course the other side I am seeing is that once you put together everything required for such a project you can have just strapped real turbines to your model and been done with a lot less pain, is that actually the issue. With turbines coming further and further under $3,000 by the day and the cost of the huge LiPo packs still over $800 is it just not reasonable to build a large scale EDF?

Like I said, I am just curious is all. If anyone wouldn't mind I would love a set of links to several of the different manufactures of both EDF supplies and model kits. I found one on here the other day for an F-14 I think it was than ran dual 90mm fans with a 60"+ wingspan but now I can't find it again, that kit looked like a hell of a lot of fun.
