They were typically heavy. They also require a lot of sanding and shaping. The Gold Edition kits build easier but are not much lighter than the older kits. If you build them as per plans and keep your balance where it is supposed to be without adding a lot of weight, they are good flying planes. They fly like war birds so speed is your friend on final approach and they have not duplicated some of the older kits. If you have the kit, build it. Good Luck, Dave
