🚨 🚨 Flex Innovations is headed to the Derby City 3D Throw Down in Elizabeth, Indiana, June 24–27! 🚨🚨
We’ll have a selection of inventory available for purchase at the event, but trailer space is limited, so we may not have every product available on-site. If there’s something specific you want, pre-ordering is the best way to guarantee availability for event pickup.
Good news: pricing is the same whether you order now or purchase at the event—pre-ordering simply guarantees availability. If there’s something specific you want, the best way to make sure you get it is to place your order now for pickup. Pre-ordering gives you the highest chance of getting exactly what you want, instead of hoping it’s in the trailer. To pre-order by credit card, place your order online, select “Pick Up In Store” as the shipping method, and write “Deliver to Derby City 2026” in the order comments. Prefer to pay cash? Email support@flexinnovations.com or call 1-866-310-3539, and we’ll place the order for you and mark it for cash payment at Derby City pickup.
If you’re attending, be sure to stop by and see us! We’ll have a huge lineup on display including the Ultimate 120cc, the all-new RV-8 35cc, Mamba 70cc G2, and a first look at the Aura Link App.
Whether you’re watching demos, checking out the latest products, or just talking airplanes with the team, we look forward to seeing you there!
