The wars in Ukraine and abroad have made the production of quadcopters and RC planes truly a mine-field for the ethical builder. As such, careful deliberation was made to define RC plane constraints which aim to effectively eliminate dual-use capability in the Yeehata Mono.

> Yeehata Mono V25

Core Objectives

The main objectives of this project are:

• Bring the highest-immersion FPV Gimbal Jet kit to market with the lowest barrier to entry in the < $1000 category.
• Remain attractive to both beginner and advanced hobbyists alike, while being wholly unfit for military purposes.
• Provide Lego-like instructions, with a second set of more technical instructions the beginner can graduate to.

Design Constraints

To achieve these objectives, particularly dual-use elimination, the following constraints were stringently chosen:

1. Thrust-to-Weight Ratio: The bare-bones thust-to-weight ratio should be very close to 1:1, which physically limits the plane from taking on additional payload (weapons).
2. Flight Profile: The plane should be fast, with a short flight time - providing high stimulation to the user in smaller-more manageable bursts, while eliminating long-range loiter capabilities.
3. Gimbal Placement: The FPV camera and gimbal will be top-mounted - a design decision that is a major bonus for hobbyists looking for immersion, and major deterrent for bad-actors who primarily look for ground-view cameras for targeting.
4. No Autonomous Waypoints: We will never provide or support "Mission Planner" configurations that allow for autonomous, GPS-based loitering.
5. Manual Control Focus: All Yeehata products are designed for active pilot input. We optimize for the "feel" of the stick, not the "click" of a mouse.

Repairability as a Standard

Instead of building a "disposable" or "fragile" craft, we’ve leaned into Modular Repairability. Because the Mono is an additive-manufactured project, a bad landing isn't the end of the plane. You can reprint a wing or a nose section and be back in the air by the next morning. This keeps the project sustainable for the enthusiast and keeps the focus where it belongs: on the craft of building and the joy of flight.
