    The airframe is completely built and covered by master craftsmen, who take their time to ensure that every part is straight and properly glued. But what really sets the Wattage Thermalaire EP apart from other electric gliders in its price range is the amount of assembly that has been done for you. The Thermalaire EP does not require any glue to assemble.
  • Page 4 The following section describes our recommendations to help you in deciding which types of accessories to purchase for your new Wattage Thermalaire EP ARF. We have tested all of these items with the airplane and found that these products will offer the best in performance, reliability and economy.
  • Page 5 Because the flight battery powers both the motor and the radio system, we suggest using an Automatic Delta Peak Charger such as the Promax Black Widow Peak Charger or the Promax Activator Digital Peak Charger (part # 885650). It is vital to the Thermal-Air EP's fly- ing performance that the battery pack be fully charged every flight, so using a peak charger is very important.
  • Page 6 We have organized the parts as they come out of the box for easier identification during assembly. Each photo below represents the parts that are required in a main section of the assembly process. Before you begin assembly, group the parts like we show. This will ensure that you have all of the parts before you begin assembly and it will also help you become familiar with each part.
