RE: Upgrading from a slowstick...wuts next?
Try any of the flat foamies. They are very respectable flyers, even in moderate winds. Also you can build them quickly with FanFold foam from Lowes and hot glue. The biggest pluses are that they are easily repaired and don't cost a thing. Fanfold comes in packs of 25 2'x4' sheets. Each plane takes roughly one sheet. $30 for the 25 pack foam, 25 planes, a hot glue stick= $1.50 per plane. There are a couple of good plans at foamfly.com. Or google free foam airplane plans. Also, try the flying wings. The Zagis and other similar planes are excellent flyers and are stable yet exciting. They're pretty versatile from slope soaring to 100 mph passes with the same plane. Just make sure to have a skilled rc pilot check out your new airplane before you fly it. Nothing's worse than destroying a brand new plane because of a stupid mistake. (Not that we don't make stupid mistakes, too) Good luck.
