Hi troyp,hold the tip of the prop. and the tip of the vertical stabalizer,if there is compression at the engine where the prop can't hang straight,then remove the glow plug.You can add stick on weight to the light wing tip,or cut the covering and add weight close to the tips with epoxy and weights,as you lift the plane the heavy wing will go down,keep adding weight untill wings stay leavel,also may move battery to light side of plane to save adding weight.
