We have combined two classic free flight models designed in the 60's by Joe Wagner. The Dakota has a 24" wing span and was designed as a fool proof Free Flight. The Dakota is all sheet balsa making it a vry durable model with .049 or .020 power. The Sioux has a 35" span with a built up wing also for 1/2A power. Both kits are $80 including postage , a saving of $13.50 and postage.
