Hi David

You got that together quickly! Must visit my loft and pull mine out.

I presume that you've got the model balanced per the instructions but the battery looks much further forward than mine will have to go. Is it a 10S 5000mAh, say about 45oz? And which motor are you using - I'm guessing that it's gotta be a 28oz Lehner 2280 to let you have the battery so far forward, otherwise my calculations are reducto ad absurdum and I might as well have bought the plane with fan ducts still installed! My whole motor/fan unit weighs 25oz and the 12S 6600 lipo will be around 72oz.

Hope the weather holds for some successful flight testing!

Cheers

Gordon
