Ron,
Believe it or not, I actually knew that, lol. Of course, lighter is most often better, but there's a tradeoff and a balance with these things, right? If we were talking about fans sitting at the extreme aft end of the plane, that'd be one thing. Where the fans live on the aircraft, you'd probably be delightfully surprised at how little difference the overall penalty is for the tradeoff in potential performance. Maybe, maybe not. Having seen the plane fly, do you think an extra few pounds of weight would be a deal-killer if you also had an extra several pounds of thrust to go with it? Rhetorical question, though, not looking to get into a peeing contest...
I have saved about 2 pounds in the airframe over the one that flew with the e-turbax setup. It probably is a little overkill for a powerplant but if you wanted a plane that screams past scale and has a more scale appearance , with the forgiving airframe i dont think there would be an issue with these fans. I would think with a glo setup you may have a few issues but with electric, the batteries will help out with that cg without adding the extra dead weight. Right now the batteries are below the rearward canopy so if need be you can slide a pack up along side the nosegear farther forward. Is dynamax using the same fan but reconfiguring it for electric? I think i was hearing about this.
thanks
