Zenoah's new GT-80 Twin is based on their powerful G-445. The 80 features an increased bore diameter, offering a displacement increase to 80cc's.

Dual rings on each piston give a superior seal, while the self-contained Quartz ignition gives a reliable spark without the hassles of charging ignition batteries. A rear-mounted spring starter makes starting a breeze. Just wind the prop clockwise one turn then release. This simultaneous firing twin is very smooth running, from idle to full power, preventing vibration related airframe and electronic problems.

The Horizon Hobby staff has been testing several GT-80s for over a year. In fact, Greg Hahn used the GT-80 in winning the 1999 Scale Masters, while other 80s have been used in giant scale aerobatic airplanes being flown in IMAC-aerobatic competitions.

They've found the biggest advantage that the GT-80 offers over the G445 is its ability to turn larger-than-normal props. Greg Hahn used a scale three bladed custom-made 24 x 10 on his Dauntless to win the Scale Masters, while their aerobatic buddies regularly use up to a 26 x 10 Mejzlik prop on their aerobatic models. The 26 x 10 turns 5700 rpm with no overheating problems, and it's very quiet.

Admittedly, they do get a bit more thrust with a 24 x 10 (7,100 rpm), but it's much noisier. Both props hover and torque roll a 26-pound aerobatic airplane at just over 1/2 throttle.

If you're looking for a reliable, powerful twin for your next giant-scale project, check out Zenoah's new GT-80 Twin.

Note: the optional spring starter (ZEN268975320, ZEN269975110, ZEN269975200, ZEN269975310) is recommended for easy starting.
