It is too much to expect of eventhe best model that it will fly in an unswervingline. Any simple vertical plane which may beturned from side to side and held in position willact as a rudder. There is great difference of opin-ion as to the proper size and position of theseguiding surfaces. It is argued by some aviatorsthat the rudder should be placed above the plane,where the air is undisturbed, while others believethat the partial vacuum created above the wingsin flight makes this rudder ineffective. Stillothers argue that a rudder placed back of theplanes affords a leverage, and is therefore moreeffective. Try a rudder in each position. It isimpossible to lay down a law for all larger models should be equipped with twin
