What makes the Spektrum P-SPMSA5070 ideal for high-performance aircraft builds?
The Spektrum P-SPMSA5070 high-speed aircraft servo with 190 oz-in torque and 0.078 sec transit time is purpose-built for pilots who demand responsive control and mechanical resilience. With a brushless motor at its core, the A5070 delivers smoother acceleration and greater efficiency than conventional servo designs. Its metal gear train and dual ball bearings ensure consistent torque delivery under high loads, making it suitable for aggressive control surfaces and rapid maneuvering. Whether you're flying aerobatic planes or high-speed helis, this servo provides the speed and strength needed to maintain control authority in dynamic conditions.
How does HV compatibility enhance servo performance?
The Spektrum P-SPMSA5070 digital mini servo for airplane and heli with 6.0–8.4V HV compatibility supports high-voltage input ranges, allowing pilots to optimize performance by adjusting BEC settings on compatible ESCs. Operating at 8.4V, the A5070 achieves its maximum torque and fastest transit speed, enabling sharper control and quicker response times. This flexibility is especially valuable in setups where power delivery and servo responsiveness are critical to flight stability and precision. The servo’s ability to act as a heat sink further enhances its thermal management, ensuring consistent performance even under prolonged load.
What role does the aluminum case play in durability and cooling?
The Mini brushless servo with aluminum case, 23T spline, and 120° rotation range features a full aluminum housing that not only reinforces structural integrity but also aids in heat dissipation. This design helps regulate internal temperatures during extended operation, protecting the brushless motor and internal electronics from thermal stress. The aluminum finish also adds a layer of durability, making the A5070 suitable for high-impact environments and vibration-prone installations. Combined with its compact dimensions and lightweight build, the servo integrates easily into tight airframes without compromising strength or cooling efficiency.
How does low deadband and high resolution improve control fidelity?
The Spektrum P-SPMSA5070 with low deadband, high resolution, and over-current protection is engineered for precision. With a 2µs deadband, the servo responds to minute input changes with exceptional accuracy, delivering smooth and predictable control behavior. This is particularly important in aircraft where fine adjustments to control surfaces can dramatically affect flight performance. The high-resolution response also contributes to stronger holding torque, ensuring that control surfaces remain locked in position even under aerodynamic pressure. Over-current protection adds a layer of reliability, shielding the servo from electrical anomalies and ensuring long-term operational integrity.
Is the A5070 suitable for both airplane and helicopter applications?
Absolutely. The HV-compatible servo for adjustable BEC ESCs with heat-sink functionality and universal connector is designed for versatility across multiple aircraft types. Its compact mini form factor fits easily into tight fuselage spaces, while its torque and speed ratings support both cyclic and tail rotor control in helicopters as well as elevator, rudder, and aileron functions in airplanes. The universal connector and 22 AWG wiring ensure compatibility with most receiver systems, and the 120° rotation range accommodates a wide variety of linkage geometries. Whether you're building a high-speed heli or a precision aerobatic plane, the A5070 adapts to your control needs.
Why choose the Spektrum P-SPMSA5070 for your next build?

- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
- Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
- If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
- For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
