Hi fellow MI flyer,
Here is another candidate for confined areas. The Flyzone FlyLite. Basically it flyies like an overgrown Champ - easy, relaxing and fun. The wing span is 35" and is a 3 channel. I fly in a field in my backyard that is roughly about 230' x 600' in size. Surrounded by mature trees 50-60' size.
Here is a an active thread on RCG of FlyLite owners.
It is available in both RxR or ARF. I started with the RxR before I found this thread. Page 5 in the thread is why I would go the ARF version if I had a do-over.
