Thanks for the advice. Based on the manual it looks like I would only need 4 servos but I guess it's good to have another one just in case. I wasn't sure exactly how the covering works. I guess as you heat the solarfilm it sticks to the plane. I found the one charger you were talking about here: http://www.hobbypartz.com/thac6smbachw.html . It does seem like good advice to get more than one battery pack. I also found a covering iron here: http://www3.towerhobbies.com/cgi-bin...XB361&P=ML . If I get the covering iron then I don't need a heat gun as well, right? Thanks again.
