Darcey, Ian is right on . You should make the call. With the plane weighing 28 to 29 lbs I want to change what I said about the distance to let it run. At about 200 feet gently pull full back on the elevator to rotate. I have heard that this plane has a very narrow window on the cg. I think Eric has one he flys all the time. He could tell you where his cg is. Then he could tell you where the planes is.....LOL..... Good luck.....Ray Blair. My e-mail is [email protected] any time you need any thing............
