HEECO / Hunt's Electronic Engineering Co.
PO Box 250
We manufacturer the ESS (Electronic Soft Start) systems that were used on the
Twinstarr rotorcrafts as an electric pre-rotator control system, and installed by Air and
Space America, Inc., (Formally Farrington Aircraft) located in Paducah, Kentucky.
The ESS system enables an electric pre-rotator starter motor to engage with a gentle
start, smoothly increasing the rotors rpm until it is ready for take off. The Twinstarr
rotorcraft is a heavy two place machine that utilizes a set of RAF 2000 rotor blades
that total 30 feet in length, and the ESS system handles the load with the greatest of
ease. ESS is the only electronic soft start pre-rotator control system on the market
today and it works great! These systems are available for purchase directly from the
manufacture (HEECO in Brooks, KY) for $495.00 plus $10.00 shipping expense.
