Why drone flight stability still matters
Stability is not a single number. It is the product of frame rigidity, motor torque-to-weight ratio, prop size, flight controller tuning, and the firmware's ability to compensate for wind, turbulence, and sudden inputs. For FPV pilots, stability means confidence — the drone going where you point it, holding position when you need to pause, and recovering cleanly from an aggressive manoeuvre without oscillating.
The Aero 1 Lite and Aero 3 Lite have both been discontinued. They were entry-level camera drones with basic GPS hold and proprietary firmware. MemAero now builds in Lancaster, using open ArduPilot firmware on hardware designed to be repaired and upgraded. The stability characteristics of the Aero 2 and Aero 3 are a consequence of that philosophy — not marketing claims, but configurable, tunable physics.
The Aero 2 — 5-inch freestyle stability profile
The Aero 2 is a 5-inch quad. Five-inch props sit at the sweet spot of the FPV world — light enough for agile, responsive flight; large enough to carry enough air for stable hover and smooth cinematic lines. The Aero 2's ArduPilot tune is set up with beginners in mind: the default Loiter mode gives you solid GPS position hold out of the box, with smooth mode transitions as you work your way through the flight mode ladder.
In moderate UK wind conditions — the kind of 15–20 mph gusts you encounter on a coastal afternoon — a well-tuned 5-inch on Loiter behaves predictably. The flight controller compensates quickly because the aircraft is light and the motors respond fast. The limitation is sustained crosswind in open, exposed locations: a 5-inch frame has less inertia than a 7-inch, so it requires more active correction in genuinely gusty conditions.
For beginners learning FPV, the Aero 2's 5-inch format is the easier starting point. The learning curve is real — FPV is a skill, not a plug-and-fly experience — but the Aero 2's tuning is forgiving enough that you are building real technique from day one. See our guide on the best FPV drone for beginners in the UK for more on what to expect.
The Aero 3 — 7-inch long-range stability profile
The Aero 3 is a 7-inch platform. More prop area means more air moved per revolution, which translates directly into smoother, more planted hover characteristics. A 7-inch quad in Loiter mode sits in one place with a stillness that a 5-inch cannot quite match — the greater rotational mass of the props acts as a gyroscopic damper against small turbulence inputs.
This makes the Aero 3 the natural choice for creators: a pilot flying long coastal transects, capturing slow cinematic passes over moorland, or holding a static position while framing a subject needs that planted, confident hover. The Aero 3's ArduPilot tune reflects this — the position controller is tuned for smooth, deliberate movement rather than snap response.
The tradeoff is agility. A 7-inch aircraft is heavier and carries more rotational inertia, so quick direction changes in tight spaces are less natural. This is not a drone you fly between trees. It is a drone you fly across them. For more on the long-range category, see our best long-range FPV drones in the UK guide.
Side-by-side stability factors
| Factor | Aero 2 (5-inch) | Aero 3 (7-inch) |
|---|---|---|
| Wind resistance | Good — fast motor response compensates | Excellent — prop inertia damps turbulence |
| Hover precision (GPS Loiter) | High | Very high |
| Manoeuvreability | Very high — responsive and agile | Moderate — deliberate, smooth |
| Beginner suitability | High — forgiving ArduPilot tune | Moderate — better once you have basics |
| Cinematic footage stability | Good with smooth inputs | Excellent — inherent dampening |
| Range and endurance | Freestyle-focused | Long-range — built for distance |
Which one suits you?
The choice between the Aero 2 and Aero 3 is not primarily about skill level — it is about how you want to fly. If you want to learn the craft of FPV, build muscle memory, and eventually fly freestyle lines or cinematic orbits with precision, start with the Aero 2. Its 5-inch format is the standard for good reason: it punishes sloppiness just enough to accelerate learning, while the ArduPilot safety net keeps the early crashes manageable.
If your interest is long-distance exploration, aerial photography over open landscapes, or capturing smooth video in challenging conditions, the Aero 3 is purpose-built for that work. Its stability profile in cruise and hover is simply better suited to those use cases than a 5-inch will ever be. Expect a steeper learning curve on launch, but more immediately satisfying footage.

MemAero has moved to UK-made FPV
The Aero 2 and Aero 3 are designed and built in Lancaster — programmable, repairable, and ownable. Founders pricing and a free spare battery for waitlist members.

The Aero 3 (7-inch) has an inherent stability advantage in wind due to greater prop inertia dampening turbulence inputs. The Aero 2 (5-inch) compensates through fast motor response, making it stable in moderate conditions but more susceptible to sustained crosswinds than the larger aircraft.
Is the Aero 2 or Aero 3 better for beginners?
The Aero 2 is generally the better starting point. Its 5-inch format is the standard in FPV, the ArduPilot tune is set up to be forgiving, and the smaller aircraft is cheaper to repair during the learning phase. The Aero 3 rewards more established stick control and is better suited to pilots who already have the basics.
What happened to the Aero 1 Lite and Aero 3 Lite?
Both have been discontinued. MemAero no longer manufactures sub-250g consumer camera drones. The company now designs and builds UK-made FPV drones — the Aero 2 (5-inch freestyle) and Aero 3 (7-inch long-range) — both running open ArduPilot firmware and manufactured in Lancaster.
