I got my self a CMP Katana 140 http://www.nitroplanes.com/katana-ae...version-2.html . I plan on powering it with a DLE 30 and it is either going to need a lot (about 30-40ounces) of lead in the nose to balance or it will need some redesigning. I was wondering if I extend the nose an move the engine forward 5 or 6 inches will it fly worse than adding 2 or 3 lbs of lead. I have done this with smaller planes but nothing this size and never really noticed a difference. I haven't installed servos in the tail yet but I doubt if I moved them in front of the prop they would make a difference. This thing must have concrete in the tail. Frustrating to say the least. Thanks for any help.
