Well, I gotta admit that I'm a stubborn SOB. and way back when, another stubborn SOB whom I shouldn't name, but his initials are Paul Lamar.... was adamant that no way ever on God's green earth would an electric water water pump have any hope of cooling anything bigger than a lawnmower. So basically... it was challenge accepted!
Now at the time there was another Ozzie frequenting this list by the name of Leon Promet who had some rotary racing experience and was a big proponent of the EWP. (RIP Leon) But he was also a great talker and an entertaining fellow whom I enjoyed reading his many post on varied aspects of rotary engines. The EWP also promised a solution to a few other issues that were certainly not insurmountable, such as clearance for the mechanical water pump which usually resulted in an unsightly and draggy cowl bump. At the time, that seemed like something I wanted to avoid, due to drag and all that $%^* but after figuring out that I never should've built an iAirplane like all the other latte sucking so called experimenters out there, I started to realize that a Van's RV, while it is a great design and is perfect for many, many assemblers out there, it's probably not the plane I should've built. Don't get me wrong, it's a great plane and lot's of fun, but it's not really the plane I should be flying. The attached picture shows the automotive equivalent to my airplane.
Anyways, at the end of the day, I've got a fast airframe with big draggy bushwheels, that while not quite a STOL plane can still cruise sorta fast, blah, blah, blah, blah.....
So anyways, I like it, I think the EWP is a great idea and it does work. And I'm an experimenter. Enough said.
