HWC/Zenoah Modified High Performance Engines

We are proud to announce we will be distributing a new line of modified Zenoah engines. The HWC Modified High Performance Zenoah Engines will be available for your helicopter bringing new standards of performance to the gas powered market.

Key Features

● 6-7.4V Li-Po ready electronic ignition with variable timing, no voltage regulator needed.
● The proven and efficient ignition system only draws 300-400mAh which allows for a smaller battery and longer flight times between charges.
● Increased power band compared to magneto engines.
● Specially designed tuned muffler included and purpose built for helicopter’s high outputs and quieter operation.
● All up weight savings of 250g compared to a magneto style engine*
*Pertains to HWC/Zenoah G23e, 26e, 29e Engines

Overview
Easier engine startup. Incredible fuel efficiency with legendary Zenoah parts reliability. HWC performance improving technology. You’ll get it all, plus power to spare, with HWC/Zenoah electronic ignition engines. The engines share many of the core components Zenoah uses in their world famous magneto engines. And, like the magneto engines, they’re built for modelers who value dependability and ease of use above all else.

What sets HWC/Zenoah helicopter engines apart is their sophisticated electronic ignition system that saves weight and makes starting much easier. The HWC EI system can be powered with 6V to 7.4V Li-Po batteries. Never needs power regulators and the current draw is so low you’ll be able to use smaller capacity battery packs and save weight.

Because the EI system eliminates the need for magnetos and other supporting components, HWC/Zenoah helicopter engines are significantly lighter as well. This reduced weight coupled with the impressive torque numbers make it possible to achieve thrilling power-to-weight ratio performance.
