Why is the Spektrum P-SPMSA6350 ideal for high-performance aircraft?
The Spektrum P-SPMSA6350 digital HV servo for giant-scale, 3D, and jet aircraft with failsafe and soft start is built for pilots who demand maximum torque and lightning-fast response. With 852 oz-in of torque and a transit speed of 0.095 sec at 8.4V, it delivers the control authority needed for aggressive maneuvers and high-speed flight. Its brushless motor ensures consistent performance with minimal wear, while the metal gear train and dual ball bearings maintain alignment and smooth operation under extreme loads. Whether you're flying precision aerobatics or high-thrust jets, the A6350 offers the resilience and responsiveness required for elite control.
How does the aluminum case improve thermal performance?
The Spektrum P-SPMSA6350 brushless aircraft servo with metal gears, dual ball bearings, and aluminum case features a full aluminum housing that functions as a heat sink, regulating internal temperatures during extended operation. This design protects the motor and electronics from thermal stress, ensuring consistent performance even in high-load scenarios. The aluminum case also adds structural rigidity, making the A6350 suitable for installations where vibration and impact resistance are critical. Combined with its compact dimensions and robust build, the servo integrates easily into demanding airframes without compromising strength or cooling efficiency.
What makes the gear train virtually slop-free?
The High-voltage brushless servo with 4.8–8.4V input, 3 oz weight, and tightly meshed gear train uses precision-machined metal gears supported by dual ball bearings. This configuration minimizes backlash and ensures accurate movement, even under heavy torque. The result is a servo that holds position reliably and responds instantly to input—essential for maintaining control during high-speed or high-G maneuvers. The gear train’s low-wear design also contributes to long-term durability, reducing maintenance and preserving performance over time.
How does the A6350 protect itself during operation?
The Spektrum P-SPMSA6350 with over-current protection, 23T spline, and 200–333Hz operating frequency includes multiple safeguards to ensure safe and reliable performance. Soft start prevents abrupt jolts during power-up, protecting both the servo and the airframe. Over-current and temperature protection monitor internal conditions and adjust operation to prevent damage. In the event of signal loss, the failsafe hold feature retains the last known position, helping maintain aircraft stability until control is restored. These features combine to deliver peace of mind in every flight.
Why choose the Spektrum P-SPMSA6350 for your next aircraft project?
The Best brushless metal gear servo with 852 oz-in torque and ultra-fast transit speed offers a rare combination of power, speed, and reliability in a standard-size format. From its brushless motor and slop-free gear train to its thermal management and failsafe features, every aspect of the A6350 is engineered for elite-level performance. Whether you're flying precision aerobatics or high-thrust jets, this servo delivers the control fidelity and resilience needed to push your aircraft to its limits.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- 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.
