RE: GP extra 300s and MOKI 2.1???
I think the Moki 2.10 will be a great combo with this plane. I've got the OS 1.60 and am just a touch under powered for full-on 3D stuff. The Moki's pretty light (comparitively speaking), so you'll be able to go with a smoke system without compromising much. Plus, the 2.10 doesn't like Nitro, so your fuel costs won't be too bad.
