New Released!! HKII-4525-520KV ULTIMATE Motor.

In September of 2010, Scorpion released the first HK-4525-520kv Limited Edition motor.  Since that date, the HK-4525 has been the motor of choice for 700-class RC helicopters, and has become the performance benchmark for every other model motor manufacturer.  Eighteen months later, in April of 2012, we released an improved version of this motor, the HK-4525-520kv Ultimate Edition.  Since then, the Ultimate Edition motor has proven itself to be extremely successful in heli competitions, and has become the most popular motor used in competition 700-class helicopters world-wide.

Many other motor manufacturers have tried to compete with this motor, but none have been successful.  We even tried for years to improve the HK-4525-520 motor but were unable to do so.  Finally, after nearly 5 years of testing and development, we are pleased to announce the release of the new next generation HKII-4525-520kv Ultimate motor, which will be available July 21st, 2017!

Through improvements in motor design and materials, we have been able to increase the efficiency and power conversion of this motor with an entirely new EM field design, while improving the compatibility with various speed controllers available on the market.  This new design motor will deliver even more power to your helicopter, with increased efficiency!

With the new HKII-4525-520kv Ultimate motor, we have once again raised the bar and created a new benchmark for 700-class helicopter power!

The Pre-order is available now and delivery after 21 July2017 !!
