comes part guys overlook Get up high enough roll aircraft knife-edge pull Up elevator Dont pull hard since havent set throw its too much will induce snap roll may recover enough times can determine whether amount elevator throw produces turn radius comfortable Dont try turn model too tightly No 1 pylon because kills speed Better cruise around No 1 pylon bang slow model down 6 Once get throw set liking try few turns like flying No 1 pylon Have friend stand 300 400 feet outside course check see model does yaw flying its side does correct situation rudder trim 7 Next thing to check model rolling turn out roll No 1 pylon pull Up elevator model should neither climb nor dive turn dives add 1/4 ounce weight right wing tip try again Keep adding weight until model turns properly model
