Yeah, I'm going to cut blades from cups, use carbon fiber for spars, and use yellow plastic tubing for the pitch adjustment part. I'm gonna try to make it lighter than 2 grams but I'll see.

Sadly, my cups are too small. Im going to cut my blades from a cylinder of plastic from a soda can. The bottle does not taper like what you're supposed to cut blades out of, but I've read that cylinders can also be used.

If you want larger pitch changes on Ikara props, careful, very localized application of heat can avoid the stress damage others have mentioned. Also very permanent. If you do it in a jig, easy to control accuracy.
You risk melting, but you'll now that right away.
At one point there was a video, but I wasn't able to find it with a short search. Been a lot of years since I last saw it.

We used to do it the way that Jeff mentions, by heating the spar. I have the video he mentions; pm me with your email address and I'll send you a copy.

Recently we have been making a hub from a 2 cm piece of 5/32" polystyrene tubing (Evergreen #225). Round off the ends of the spars a bit and you get a snug fit that can be easily repitched, then held in place with a bit of Ambroid or Duco cement.
