I have the 4*60 arf w/ a Saito FA91.It took me about 12 hours to get it together.I had the problem w/ the wing dowels,but that was about it for assembly.The trouble I ran into was setting the CG.The plane ended up a little tail heavy(probably epoxy).Using a 14x6,the plane takes off in about 15 ft. of runway.Extremely stable in flight.All in all,a great bird as a low wing trainer yet will do some fancy flying as well.I would suggest it to anyone.
