never touched my glow planes. but i touch my Fiton jumping jack and EF yak 55ep all the time. i once ran almost an entire pack torqing about 1 foot off the ground then stopping the torqe and touching.. but it dont happen often due to wind. a 20oz electric is really sketchy in a 10 mph wind. luckily i had such fun last sunday.. it was dead calm.. maybee that because it was raining

off and on..
havent had the nutz to break the rudder of my glow plane yet
