It's an old Comet Puss Moth. I'll try to put a photo of it in my photo album here on the site.
The airframe with aluminum rear motor peg is 4.2g. The prop with shaft and nose block is 2.3g. Ugh! It dives in the glide, but I haven't flown it under power yet.
I single covered the wing and stab according to the plan, per original Dime Scale rules. I see now that "pseudo-dime" might be run at the contest, which calls for double covering on all new designs. I'll bring my old standby Stinson just in case I can't compete with the Puss Moth, but my goal is to break 2 minutes with a cabin model, contest or not!
That's a great link to prop carving instructions. Might have to give that a try.

Otherwise hand carved or machine cut wood is OK. I've never carved a solid wood prop before and time is ticking, so I was hoping to find a lightweight plastic prop that meets the one-piece MOLDED requirement.
