Scorpion HKII-4525-520 KV - ULTIMATE
Some products
The second generation of the 4525 series (replaces the HK-4525-520)
The new HKII-4525-520KV ULTIMATE brushless motor is wound with a single strand of 1.4mm wire for maximum efficiency.
This latest generation motor is capable of continuous operation with an input power of 4450 watts at 100 amps and handles peak currents of 10200 watts and 230 A (max. 2 seconds).
With the HKII-4525-520kV Ultimate we have once again raised the bar and are redefining power for 700 helicopters!

The popular Limited Edition HK-4525-520kV Scorpion Motor has been available since September 2010. The HK-4525 is the performance benchmark for 700-class helicopters.
In April 2012, eighteen months later, Scorpion presented the enhanced edition HK-4525 Ultimate to the public. This engine is one of
most popular engines in 700cc helicopter competitions around the world.
Many other manufacturers have tried to hold a spark plug to the engine, but none have succeeded. Even Scorpion tried to improve the engine and failed for a long time.
Now 5 years later, we are proud to present the HKII-4525-520kV Ultimate.
By improving the materials and design of the motor, we have succeeded in improving the efficiency and energy conversion of electricity into rotary motion.
The HKII offers a completely revised EM field design while maintaining its high level of compatibility with all controllers on the market.
This new engine has more power reserves with higher efficiency for your helicopter.
