Do they come already wound up and ready to fly?

We do not offer our FlutterFlyer pre-wound. You will need to wind them up prior to use. Please use your best discretion when deciding who to give or send a FlutterFlyer to, as the shock and surprise of the product may not be suitable for all individuals and it is your responsibility to ensure the safety and well-being of the recipient. By purchasing and using our product, you assume all responsibility for any potential adverse reactions from the recipients of the FlutterFlyer.
