3. RCRAFT COVERING 1 With all ARFs varying temperatures and storage delays can cause the covering material to loosen over time during transportation Slipstream recommends lightly going over all the covering with a covering iron set at medium temperature Be sure to use a soft covering over your iron so that you do not scratch the covering surface Be sure you go over all seams and edges of the covering to assure it is secure to the airframe and other covering Be careful not to apply too much heat or you may cause bubbles or damage to the covering A heat gun may also be used along with a soft cotton cloth to shrink loose coverings Be extremely careful when using a heat gun 2 Be sure to seal any exposed wood with a thin coating of epoxy to prevent engine oil from soaking in This is especially important around the engine compartment and servo openings with exposed areas 3 Some modelers prefer to seal the hinge gaps using strips of appropriate covering or clear trim tape We have found this to be helpful with models intended for higher speed flight or models with unusually large hinge gaps Slipstream aircraft utilize a very tight double beveled hinge line and do not normally require this step Sealing t he hinge caps is therefore left as an option for the modeler RUDDER INSTALLATION 1 2 Locate the vertical stabilizer rudder and the tail gear set Install the vertical stabilizer Cut away the covering where the vertical stabili
