(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 channel radio for aiplane is highly recommended for this model. -cycle.0 9 Optional parts: rubber wheel with metal hub. Spinner X0 We strongly recommen you use the thread lock for all the screws when you build your model.
