That link does not work for me and the DA-50 they show looks nothing like a Dessert Aircraft 50. I would not be surprised if they listed it w/o even thinking about it. I know they don't like to remove links but it's showing out of stock anyway.
I think I have purchased around 10+ planes from them over the years. Only the older CMP kits was I displeased with. The newer CMP stuff is much better. But you can't compare a $100 CMP ARF to a $250 Hanger 9. Often the foamies need some mods but still better bang for the buck than parkzone. Easy to get mods and feedback on the stuff before you order from RCGroups or here.
