Parkflyers, like any light weight plane, will definatly be more sensative to the wind.

I point out that a park flyer is not necessarily a slow flyer or a plane that can fly in a small space. A ZAGI wing is not going to be appropriate to a 100 X 100 foot space out your back door. In fact some of the ZAGIs his over 70 mph right out of the box.

If you are looking for something you can fly in a 1/4 acre open spaced in your back yard or in front of the house, you really need to look for a electric slow flyer like a slow stick, a tiger moth, an IFO or any of a long list of small, light electrics.

There is also a long list of fully 3D electrics that can be flown in this kind of space such as the shockflyers, or an IFO. Again these are very light planes at under 12 ounces all up weight. Their small space capabilites are based on the fact that they are very light, can be launched vertically and are so wildly aerobatic they can literally loop in twice their fuselage length. They can also be pretty pretty fast as they are flying with better than 1:1 thrust to weight, but it is their slow speed capabilities and 3D capabilities that make them suitable for indoor or small space flying. You need quite a bit of flying experience to be able to really fly these in small spaces and again they are not going to like a lot of wind in a small space.

None of these will fly well in over 5 MPH winds and few can handle 10 MPH at all, however if you are aware of that and can find relatively calm air around your home often enough, small light electric slow flyers or fully 3D flyers are great!

1/2A glow planes just aren't going to be able to do what the slow fly electrics do which is fly close and quiet in very small spaces.
