Ran almost 9000 RPM at 40Amps. Neither motor or speed control got very warm after a couple of minutes of testing. I was planning to run this on 4S in a Kadet 25, but thinking 3S might be enough. Taking a wild guess; thinking this might be a .32 class motor. Update: Aug 8, 2023. Finally flew it. Flew fine on 3S with 11x7 prop, but on 4S with 12 x 8 - Wow! Review: Exceptional power - I have 2 of these motors and the power is simply amazing on 4 cells. ## Features - Motor KV800, power 1250W, applicable voltage 7.4V-14.8V - Adaptive blade: 13x10 / 14x7 / 14x10 is recommended，motor output is welded with 4.0 mm banana male head and 4.0 mm banana female head - Material: Aluminum Alloy + Copper, it is lightweight and portable, with stable and low‑noise working performance, fit for RC fixed-wing aircraft with 4.0mm banana plug. - The precisely balanced rotor is stable, has the best reliability and the largest RPM, precise design can achieve maximum energy conversion and outstanding performance. - Strong thrust, high efficiency, low power consumption, high performance, exquisite workmanship, easy to install, it is used to replace the damaged or unusable motors, with simple operation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09BZ26W4W | | Best Sellers Rank | #71,928 in Toys & Games ( See Top 100 in Toys & Games ) #32 in RC Electric Motors | | Brand | DIAMONDDYNAMICS | | Brand Name | DIAMONDDYNAMICS | | Customer Reviews | 4.4 out of 5 stars 61 Reviews | | Horsepower | 1250 watts | | Included Components | nothing | | Item Weight | 216 g | | Manufacturer | Hobbyhh | | Material | Aluminum | | Material Type | Aluminum | | Number of Items | 1 | | Part Number | D4250 | | Shaft Diameter | 4 millimeters | | Speed | 60 kilometers per hour | | UPC | 781855994927 | | Voltage | 7.4 volts | ## Product Details - **Brand:** DIAMONDDYNAMICS - **Horsepower:** 1250 watts - **Material:** Aluminum - **Speed:** 60 kilometers per hour - **Voltage:** 7.4 volts ## Images ![Hobbyhh Brushless Motor 4250 800kv Power 1250W with 4.0mm Banana Head for DIY RC Glider Aircraft Plane and UAV - Image 1](https://m.media-amazon.com/images/I/61xbWjKKvIL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice Motor - 8700 RPM on 3S, at 40 Amps with a 12X8 Zinger Prop on the Test Bench. *by B***B on October 30, 2022* Bench Tested: 3S LiPo, 5200mAH/50C Battery, 80A Speed Control, 12x8 Zinger Wood Prop.
