Help! HELP WITH A HIGH SPEED SPEEDWING

[Zoom Master]

Im currently designing a high speed rc speedwing.

And I need help with the wings and the horizontal and vertical stabilizer. I first am trying to figure out how im gonna mount the horizontal stab on top of the vertical stab. And I also wanna know what wing will be best for high speeds out of these 3

I really cant build this pylon until I have these issues sorted....

Out of those 3 wings, the bottom would be fastest. But I recommend changing it still. Try adding a little bit of sweep to the leading edge on no.2 and it’d be the winner

Kinda like the leading edge on this.

Ok so the bottom is the fastest but if I add sweep on the leading edge of number 2 that would be the fastest got it !

A lot or just a tiny bit ?

 

[Mr Man]

Just a little bit, about the same as that red plane..

Okk here it is (the last one)

since im currently only making this out of foamboard im gonna try out all 3 wings to see which one is the best and then pick that one for the carbon version !

Nice! I’m still saying the new no.3 though 👍

From an aerodynamical aspect

Well let’s test that out !

Here is the side by side comparison of the 2 final wings

And also for the foamboard plane should I go with a vinyl covering or paint the foamboard ?

And if so any color scheme recommendations ? (that will make my plane easier to see in the bright blue sky) Im currently thinking orange.

Ok so question why do dynamic soaring gliders have wings with no sweep whatsoever (like wing 1)

And this Is btw how big I wish my pylon was 😂

If you notice though, It does have a constant taper toward the tips, so basically a very slight sweep, but a flat trailing edge.
