(The people under years old is forbidden from flying this model) First-time builders should seek advice from people having building experience.if misused or abused,it can cause serious bodily injury and damage to property. Fly only in open areas and preferably at a dedicated R/C flying site. We suggest having a qualified instructor carefully inspect your airplane before its first flight.please carefully read and follow all instructions included with this airplane,your radio control system and any other components purchased separately.

2 6 (with 3 servos), 6 6 channel radio for aiplane is highly recommended for this model. 6 : -cycle.9 Spinner nut "x7 Apply Warning Remove the covering with proper pressure to cut through only the covering itself.otherwise, cutting down into the balsa structure may weaken the model part and cause accident. Pre-cover the covering with clean cloth! Start at low setting. Increase the setting if necessary.if it is too high,you may damage the film. The pre-covered film on ARF kits may wrinkle due to variations of temperature.smooth out as explained right. with cover(cloth) Iow setting
