sad face, you just peel the lower wing out. Don't cut it. If you don't like the flight parameters peel out the hot glue, put you lower wing back in, and go. If your not comfortable soldering electronics for dummies will help. I recommend a 25w or higher soldering iron(I use 25w) and practice on small paper clips. Reading glasses are an immense help as well. have fun Tim

Funk, I think the temp rule has to do with the battery. The high here on thursday is supposed to be in the low 40's If it's dry I'll be flying. It does seem to use more battery though. I get 18 charges on average from regular batteries. For more info on rechargable batteries try the aero ace mods sticky, I think that info is there. As to the Lipo inside the plane I have had no luck finding them in the states. I'm still looking and when I find them I will post that info both here and on the mods page, Tim
