AUW is right around 6oz, and I'm sure you could go lighter using less glue, no tri stock, and lighter electronics.
I took the plane out to my mom's gym for the maiden. This was the first time I've ever really "flown" inside, I have hovered stuff indoors alot, but it never really left high alpha. The plane was pretty easy to handle with 30% expo on the ailerons and elevator, and 35 degree throws all around. The hacker on 2S is very peppy, and not lacking in power by any means, I only took it to full throttle once, and it was way too fast for indoors

It torque rolls smoothly, harriers have no rock, and it floats like a feather. Since this is a new plane, there isn't a definite CG yet, so next flight I will move it back a little, and give 45 degree throws all the way around, and hopefully buy a radio with some rudder exponential [>:] I should have a video of the flight up by tomorrow. Enjoy!
