Before gluing the fusalage together open up the battery compartment so that the battery can be slid more forward. The recommended CG is a bit far back on this bird (short nose). Mine flew very squirrelly until the CG was moved forward. The supplied glue is really a form of contact cement. If you use it...apply to both surfaces...press together and immediatly separate. Let it dry for about 5-7 minutes and then carefully put the halves together. (Unfortunatly not in the construction manual)It will not allow you to adjust the parts so be careful. If you use the glue like epoxy it will just sit there and will take about a week to cure (if at all). Definatly not a beginner plane but flies nice in experienced hands. Some other mods to consider are lowering the angle of attack on the wing with a small spacer under the LE where it sits on the fusalage. Some others have slightly raise the leading edge of the horz stab with almost same effect. I have 3 tiny sets of rare earth magnets holding on the wing. Less damage in the event of a cartwheel landing. good luck.
