If this is the Fabric Covered GP Cub I will have a few Tips for you...You might want to look at Changing your struts..I had nothing but trouble with mine untill I made up a set out of stream line tubing...The GP ones are hinged with CA hinges and they do not stand up very well...You will get a few flights out of them but mine failed about 5or 6 flights in but that was on water....It is a wonderfull plane...I also eventuly put Robart landing gear on mine because I liked the plane so much...It is great improvment...Make sure you have sombody who is farmilliar with Cubs help you with take offs for the first little while..They can be a hand full untill you learn how Cubs are to take off...You need to learn how to use your rudder properly...One other thing my wing joiner did not fit very well and I ended up making another one..This was back a few years so maybe its better now...Spend the time on your wing joint getting it rite..It is a one piece wing and the joint needs to be strong...I broke one wing dumb thumbing mine...If I wrecked this plane I would replace it and I cant say that about most of my other planes....
