Some countries and states have very strict laws on where you can fly your remote control airplane and require notification of all those who intend on flying their planes outdoors. If all you intend on doing is displaying your airplane in your home or man cave, registration may not be necessary. However, most states will ask you to email your remote control airplane as a form of registration. Once this process is complete, you will be given a registration number that will cover any new remote control airplanes you add to your collection. If you are in doubt as to whether or not this is necessary, your best bet is to contact your local authorities and ask. Another useful source of information is to contact your nearest remote control airplane flyers’ club. The members here will know if registration is required and will be able to tell you how to get this done.\r
