Lothar! that was the man. Very nice guy. ( but then they all were.)

As for Walter,.....I don't remember him by name although I'd probably remember his face. Sad news, poor chap.

Do you remember that guy from Germany (can't remember his name $:-\$ ) who had built a couple of Horten wings and flew them during Retroplane Ireland?

You could always recharge the battery in situ, between flights David. Save having to "dismantle" the plane!

All looking good David.

Points to note
Speed controller: I see the ESC is only rated to 12 amps. Too late to change it now as you've already bought it but if the motor is going to draw 11amps it would have been safer to have an ESC rated to about 14+amps
At high power levels the ESC will likely get quite warm/hot, as will the motor. They will need some cooling so place them where there will be an inrush of air. (And allow for an outrush as well because if the incoming air can't escape then no air will flow.) The battery can also get warm BTW. So bear these facts in mind when you're deciding where to locate them.

Question: Is the diameter of the wires from the Red (so called) BEC connector, (the one that will connect your battery) the same as the diameter as the black & red wires from the ESC?
I didn't think BEC connectors were rated to 12 amps, though I might be wrong. $:-\$

Ha!,at full throttle she'll be very fast I'd say.
It'll either put a smile on your face, or something less welcoming in your pants!

Just out of interest, what size prop will you be using David? Due you have any idea of the intended All Up Weight of the model? (including the motor and battery)

Ah, now I can see what you're talking about!

Much easier to work on stuff when you have an assigned room, rather than on the kitchen table isn't it. Can be a wee bit chilly in the attic though. I had an attic workshop for years and found it cold in winter and hot in summer, but beggars can't be choosers. At least you have somewhere. (I found fingerless gloves a benefit during the winter. And a woolly hat. Ha!)

Well, it all seems to be coming together quite nicely. Did the motor come with the kit or have you just purchased one that they recommended?
Looking at the wing leading edge, is that the final shape or does it need a bit more "rounding"? From the picture it looks a little 'flat fronted' David.
You're certainly getting on with it!
