Sorry guys, I had totally forgotten about this thread... and missed it when I was away.
Should be sweet
Go for it! The only hiccough that I can see is possibly keeping the wing from flexing too much... What were your thoughts on spars etc?
I might put a 3/16" (5mm) round wooden dowel in the wing to reinforce it. Curved like when Josh Bixler put fiberglass in the speedwing.
Looks good. The motor choice sounds good, too. It will have plenty of power! SteveO is right about spars - definitely need something to reinforce it. Don't worry about the weight from the tape. THat motor will push it around just fine.
The motor will be OK - but it won't be fast. The Kv on it is 1000, so the max speed would be around 40 mph. But it will go vertical
Wingspan = 100 Is that cm? If so that will probably work well with a 450 motor. What KV?
I prefer more sweep. It makes the wing a little less sensitive to cg. Try plugging 30 into the sweep field and see how that looks to you.
What kind of airfoil are you using?
Are you hotwire cutting the airfoil?
Or doing a KF airfoil?
To get the most out of the tape's ability to keep the wing from flexing, you may consider taping to line up with the LE and TE of the wing.
Checkout the taping pattern that my friend Adrian uses for his ExtremeWing:

Yes, 100 is cm. I decided to change the design a bit, and add some more area.

I am planning to do a KFm2 airfoil - with each layer of 2 cm, or 3/4". Total thickness 1 1/2".
Thanks for the link, I'll follow that guide if the foam allows me to do it.
Surely you can find blue core or pink foam insulation?
I cannot.
I doubt Andre has that in Ecuador. Its warm/hot year round and I doubt there are building energy codes like we have here in the states. But, even though it is brittle, the "cooler" foam, reinforced properly and not flown like our combat wings, is probably a legit material.
Teach is right
it's always hot here, so no need for insulation.
Andre, I was wondering if you've thought about trying your hand at making a hotwire? Even the nastiest EPS will come out with a nice finish if you can use a hotwire.
I have not, as I have not come upon a free computer power unit. And my poor e-guitar is stringless.
To keep on post. Andre what's up?We are waiting to see some pictures
Eventually there will be pictures! But of what, I do not know, for my Park450 has been changing it's planned location a lot
First a tricopter thrust booster, then a profile 3D biplane, then a single wing profile 3D, then a balsa Extra 300S, then a swamp boat, and now a flying wing... We'll see...
What IS Andre up to? Last I saw, he was apparently eating pizza...
The pizza was really good!
