Like doubledee I made similar mods to my Big Stik 40. It is an ARF with a Saito 82 - things changed:<ul>[*]battery box under the rear wing mount block,[*]throttle servo tray (only 1 servo) placed just in front of the battery box[*]elevator and rudder servos relocated to the side and top respectively of the fuse[*]tail dragger[/list]After all said and done it balanced without the use of lead.
