I would not use music wire for the rigging wires unless you need the weight to get the cg in the correct position. This model has a short nose so the weight of the wheels plus the dummy engine should be already enough to get a good cg.
 
7g without rubber is a good starting point for a monoplane peanut model. However the lighter model will always fly slower and longer and suffer less damage when "arriving".
 
I'm sure you get lots of better advice over on the HPA forum.

Hello guys,
I just uploaded a photo of my progress on my Peanut Scale project. It's a Sommers Monoplane and the fuse will be pretty much all, with the bottom of the fuse, will be uncovered to show the wiring and to keep it light.
With what is in the photo I'm at 2.75 grams.
I just finished making an aluminum wheel and it came in at 1.95 grams with the rubber tire mounted onto the rim.
Once I make the other wheel and mount the tire onto it I'll be at 6.650 grams and I still have to make the landing gear rigging and the cable rigging that stands in front of the pilot. I'm thinking of using .015 MW for the rigging (.57 gr + 6.650 = 7.22gr.).
I'm covering the flying surfaces (wing, stab and rudder)with condenser paper.
Let's say I'll be at 7.5 - 8 gr AUW. Does that sound like it'll fly or am I too heavy and need to take something off?

It's my first attempt at scratch building a peanut scale model and I sure would like some input on this before I keep going down the wrong track, if that's what I'm doing.

thank you,

Ren
