O.S. Engine 18TZ-TX w/Roto Carb  [OSMG2113]

For today's competition motorist, turbo is the option to go...and no other turbo motor goes like the 18TZ from O.S. It outperforms all the .18-size machines, delivering race-winning ??outlaw?? energy for 1/10 scale buggies, stadium vehicles and touring automobiles.

In a current dyno test for the next issue of RC Nitro Magazine, the new O.S. 18TZ rear-exhaust motor cranked out a record setting 2.28 bhp at 30,500 rpm. Steve Pond, R/C Nitro magazine

Oversize fins regarding the instance dissipate temperature to keep engine temperatures reduced.

Five ports in liner increase venting for lots more power.

A corner bearing is 12 mm in diameter, which lessens vibration and enables the engine to carry out more torque.

A super-hot turbo P3 plug is included for better burn, more energy and enhanced fuel economy.

The 18TZ-TX version features a new compact recoil starter that's smaller and lighter, making it easier to put in.
