RE: U can do 3D .46&.61
you would be happy with either because their both great planes and a saito 82 or a saito 100 4stroke will do respectivly. you need to beef up the control rods on both. both are good beginner 3d planes and fly good. i would go with dubro pinned hinges right off because ive had the ca hinges fail on them and the pinned hinges will last. you will need a servo reverser for the elevator and a y for the ailerons.
good luck Gary
