I built this plane and it was partialy covered and painted. I built it a little heavy because of wing mounting changesand nose gear beef up. I used an OS 120 and dual battery backer system. Total weight was al;most 17 lbs .It flew like it was on rails, and did nice crisp rolls, etc. It was not to bad a kit to build,with laser cut parts etc.I made a "dumb thumb" move low and it caught a wingtip and after 4 cartwheels itwent back to kit form. I would build another one if I could find one. I am also flying an Aviomodel Cardinal, with an OS 120, and it flys even better than the Arrow. I have a backup kit for the Cardinal. In any case a good flyer. Rich
