Just curious, because I think too much sometimes...Why would you have the flap section down and then elevon deflect up, during take off etc, when I would think the flaps and elevons in opposing directions would simply create lots of drag working against each other? OR is that the flaps are toward center and more forward, perhaps of the center of lift, giving the same effect as the elevons which are more rearward of the CoL?
On the Swift the inboard flap produces a nose-up moment when deflected downward. No elevon deflection is needed to trim with the flaps deployed. The name Swift is actually an acronym:
@smorrismlbco Aha. So I think my vague theoryabout the effect of the flaps is somewhat correct, that they are located in a such a way that they produce the same effect as the elevons control wise. It makes sense now. :) Thanks. Very cool. Who'd think someone would actually fly up with lipos in a real craft (what with all the scary stores people love to tell about their r/c). Been using lipos in r/c myself, never thought someone would use them in a 1:1 vehicle!
@smorrismlbco Steve or Brian, How about the elevon deflection for take off? (im triyng to build something like the swift and right now i have to set those kind of things) Thank you !
It depends on your CG position and all of the exact details of how your wing is built, especially the landing gear location. The E-Swift can lift off with zero deflection if you build up enough speed in the take-off run.
@smorrismlbco Yeap, my cg is already located and stuff, but it`s getting hard to understand why the swift would need such a large elevons. By the way, GREAT work ! should be beautiful to fly the E-Swift without the noise of a combustion engine!.
Nice plane. How did you get permission to fly out of that nice airport? I am finding out that not many airports and pilots here in North Texas like ultralights. I have a Sabre 340 Trike and I am just looking for a small non controlled airport to fly out of but no luck so far. My next one I will try is Caddo Mills,TX.

So a range of about 90 Kilometers?
(1.4 hours at 35 kts)

15 degree flap for most of the flight, 35-50 degree flap for landing.

OMG I WANT ONE !!
Swift plane the greatest thing ever for pilots =)
<3 one day i will build one and even if i die flying it
its all worth it in the name of science.

I assume that the batteries are in the two white housings on either side of the pilot?

Those are Kevlar molded battery boxes. Inside each is 72 10-AH Lipo batteries wired for 67 Volts. The 2 sides are connected in parallel.

Hello where can I buy a glider like this
because this is what we need in Kongo.
My company is in Europe.
Fantastic movie

What do you figure for the cost of batteries, motor, controller, etc?

Approximately $15K for the electronic propulsion hardware.
