I am using the JSC blades and really like them. They take a lot more abuse for a newbie to helis than the stock blades.
Also got rid of the styrofoam balls on the training gear and added some toy balls from Dollar General. They are called Water Bombs made by Sun & Shade, they cost $1 for a package of two. They are very light in weight and hold up a lot better than those little styrofoam ones. Don't laugh at it too hard now, ok.
