I happen to have a 90mm AirPower Fan (http://www.airpowernet.com/twe/index.php?cPath=88_90) in my drawer alongside with a Mega 22/30/3 (http://www.puffinmodels.com/MEGAAC2216pictcoman.pdf). I am planning to scale up the EZE-Fan by 33% for this fan-unit (68mm * 1,33 = 90,44mm!) Will this be a good combination? There are very few kits available for a 90mm fan, so when I saw this plan last summer I decided to try to enlarge it. Any recommendations on battery-pack and regulator will be appreciated!
