Ok now that I've completely read Stu's post and watched the video, I've got to order one for my E-flight F-4.
The fan is a done deal but the motor I'm having difficulty with - any suggestions or thoughts would really be helpful thanks.
I have a bunch of 4S 4000 packs but I doubt 4000mah will be enough for a +3kw fan setup (with any reasonable flight time that is). I personally don't fly at WOT all the time but three minutes is a bit short for me - I'm just starting to settle the nerves down from the takeoff by then
I also have 5S 4000 so I'd hate to have to go 6S 5000 packs if I can avoid it.
