We are targeting a Kickstarter launch in December 2026, with the first production batches estimated to ship globally from Q1 2027.
The $799–$1,399 range shown on esdyn.com reflects different configurations and crowdfound phases; It is not a final price list. Kickstarter backer pricing will be announced when the campaign goes live, and it will be tiered by campaign stage — so what you pay depends on when you pledge.
You can subscribe at esdyn.com to receive a launch notification. Subscribing does not reserve a unit, lock in a price, or guarantee early-bird availability. We use your email only to send launch and campaign updates, and you can unsubscribe at any time. See our Privacy Policy for details.
We do not recommend flying in Beaufort 6 (39–49 km/h) or above.
Yes, with a compatible setup. EAGLE X has an ExpressLRS 2.4 GHz serial receiver running firmware 3.6.4. Your radio needs a compatible ELRS 2.4 GHz internal or external transmitter module; being a 2.4 GHz radio alone is not enough.
Send ESD your radio model, module model and ELRS firmware version so we can help check compatibility.
The transmitter module and receiver need the same major firmware version. For the supplied 3.6.4 receiver, use compatible 3.x transmitter-module firmware. For example, 3.4.2 and 3.6.4 share a major version; 4.0.1 and 3.6.4 do not.
Follow the appropriate binding procedure for your hardware. Ask ESD if you are unsure.
The mapping is AETR: CH1 Aileron, CH2 Elevator, CH3 Throttle, CH4 Rudder. EAGLE X uses the first three channels.
Following ESD guidance, check the bare fuselage with wings and tail removed. Start with throttle at its minimum and keep hands clear of moving parts. Confirm each stick’s output and aircraft response. Reverse the corresponding channel in the transmitter if required, then check again.
Disconnect the battery before fitting the wings and tail. If the correct response is unclear, contact ESD before flying.
Choose Mode 1 (right-hand throttle) or Mode 2 (left-hand throttle) when ordering. You can also change the stick mode yourself later, following the transmitter manufacturer’s instructions.
Changing modes can involve physical stick adjustments as well as transmitter settings. After any change, confirm AETR channel mapping and control direction before flying. Ask an experienced technician if needed.
Stabilized flight mode supports learning, but flying still takes practice. New pilots should get help from an experienced RC pilot and begin with basic maneuvers in a clear, open area.
Use the ESD high-performance custom battery. The standard pack is 850 mAh. Ask ESD before fitting another battery: weight, balance and electrical specifications matter, not just capacity.
Blade-free means there are no spinning propellers. The wings, moving mechanism and aircraft can still cause injury. Keep spectators, children and pets clear of the launch area and flight path. Children need adult supervision.
The $10 reservation is a deposit, not the full aircraft price. No physical product ships with the reservation. Product purchase is completed separately when the Kickstarter campaign opens.
Email signup is free and separate from the reservation. See the current reservation terms for applicable benefits and conditions.
Contact ESD with your aircraft or transmitter details. Ask us about compatibility, replacement parts and applicable after-sales terms before making a purchase decision.
ESD (EagleSight Dynamics) develops bionic flying robots inspired by birds. From aerodynamics to intelligent flight control, we turn research into aircraft made to be flown.
Our team brings together PhD researchers from Shanghai Jiao Tong University and professionals with experience at DJI, Huawei and ByteDance. With Eagle X, we're bringing ready-to-fly bionic flight to people who love to explore, build and learn.
