If your running the Rimfire, Id highly recommend the ChargerRC CR-1 or CR-2. Great airplanes, and fly way better than the funtana.
You will have to modify the aluminum motor mount, but combining a Rimfire and the CR-2 will give you a fantastic plane capable of indoor or outdoor flight.

You can have this thing literally built in a matter of minutes. You dont even need a table. I built mine on the bed while watching tv. Its got tabbed construction so it goes together really quickly. Its all 6mm depron, and extremely durable.

Here's a video.
