Great idea Marc, and a nice choice of subjects. As for power, I think I would be looking at something like the Webra 1.20 two stroke or possibly an OS 1.08 if you can find one. At 67 inches I doubt you will go 15 pounds unless you really go crazy with the detail and paint. Here's what I can offer to help you with your project:

- I know several people in the Valley with laser cutters and can help you with that at a really low cost. (like $35/hour for laser time) We could probably cut your entire kit in about an hour if we had everything set up and ready to go before hand.
- If you need any vacuum-forming done just let me know and we'll have a go at it.

PS - I like the obscure Russian birds as well, check out my current Yak-11 project over at RCSB if you're interested.

Also, take a look here for some great walkaround pics of the full size Mig-3 restored to flight status in Russia.
