Prop size!
Whirley it didnt take long at all to build but if your like me who has never had to mess with mixing channels that part can take a bit longer then building the plane hehehe. Its one of the most well finish ARF that I've bought and thats not to say that their isn't others out there that are well made but everything fit almost if not perfect. The best part is that for the price($130 or less) all you would need to finish it is small bottle of epoxy(5 minutes kind will do) and ca glue and radio(7 ch for crazy speed spin) and engine of your choice.
