So now I am thinking about how to make this thing faster, maybe a swept wing. I am wondering if I just cut the wing halves at the centerline 20-30 degrees and joins them... what might happen. Drag down? Lift?

You will change the CG and the stability of it, but I think it's a novel idea

My first thought is always adding voltage, but using my brain might be a better idea to alter the design. Wing is thin already, fuse area at firewall cannot be shrunk since motor mount is huge. Wing mod seems the most likely solution.
Another idea would be to reduce wing chord length?

You use Adobe Reader. You load up your document, click on the printer icon, and you can scale it up or down, and it also tiles it for you if you select the poster option

Wow - that’s a rocket for sure!! I’m terrible at guessing but I’m gonna say it’s over 90 for sure, but considering the motor is out of a v900 and that thing can hit 120 I think, you could well be venturing into the triple digits! @SquirrelTail is a good guesser on speed so I bet he could give a more accurate guess.

Your probably doing around 120Wow - that’s a rocket for sure!!

i have both the mini and micro balsa demons. got a few guys at the field to buy the mini and we are going to start a racing thing. should be fun.
well one of those guys showed up today with foam speed deamon. flew great and was actually really good practice for him come time to fly the balsa version. one thing lead to another and now i have this on my table...
ecalc said 99mph with a 4S 6x4.5 prop.
still playing with props but will have to test.
laters,

I built a cleaned up version with a tighter nose, bolt-on wing, and then gave it the Nerdnic treatment. It flies AWESOME. On 6s it's very quick and handles really well. Landing speed is a little higher with the big motor and isolated receiver battery/bec, but still very easy to land.

have seen the speed wing... just didn't put two and two together I guess. Do you feel his wing design is faster?
