Shipping & returns Carriers: Full Send FPV uses the United States Postal Service for most shipments, however, we may use other carriers to deliver your order (typically for lipo battery shipments).
UPS Shipping: Note, that UPS does not deliver on Saturdays. We recommend using USPS for all shipments, but UPS is an available option.
Lost Packages: Full Send FPV is not responsible for lost packages. No refunds will be provided if your package is lost in the mail system. It is our recommendation to select the Priority Mail option with the United States Postal Service to ensure that packages are not lost, and that you have at least $50 in insurance. Priority Mail has the most reliable package tracking to ensure packages arrive at their specified destination.
Shipping Time & Delays: Unless otherwise indicated, orders received prior to 4 pm with payment received will usually ship that day, unless it is a holiday or non-business day.
Delivery timeframes provided are estimates and will depend on the carrier. Full Send FPV will not be held responsible for any delays caused by a mail carrier or local postal service.CLICK HERE for the full Shipping.& Returns Policy
