Versatile VG performance, with an O.S. Easy Start!

Drivers love the power and speed that the 30VG engine delivers, and now it comes with another huge benefit: even easier, more reliable starting! The 30VG (P) ES is equipped with a backplate that allows for using a DuraTrax® Kwik Pit® Super Start or HPI Roto Starter ignition system. The 30VG (P) ES is a performance booster for large monster trucks, or as a drop-in upgrade for RTR buggies.

The 30VG (P) ES engine still has these popular features:

• An ABL piston liner that breaks in easier and lasts longer.
• A one-piece crankshaft, preferred for 1/8 scale off-roaders.
• An easier-to-adjust 2-needle carburetor.
• A wider, one-piece Tornado head.
• A straightforward design for economy and easier maintenance.

Premium power for the serious racer!

For today's competition driver, turbo is the way to go...and no other turbo engine goes like the 18TZ from O.S. It outperforms all other .18-size engines, delivering race-winning “outlaw” power for 1/10 scale buggies, stadium trucks and touring cars.

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

• Oversize fins on the case dissipate heat to help keep engine temperatures lower.
  
  
• Five ports in the liner increase airflow for more power.
  
  
• The rear bearing is 12 mm in diameter, which lessens vibration and allows the engine to handle more torque.
  
  
• A super-hot turbo P3 plug is included for better burn, more power and improved fuel economy.
  
  
• The 18TZ-TX version features a new compact recoil starter that's smaller and lighter, making it easier to install.

O.S. 18TZ Application Chart

Taking R/C to extremes takes power and O.S. 18CV-Rs have it to burn.They mount in the same space as a 12 or 15CV, but deliver the punch of a big, booming .18 cubic inch (3.0 cc) displacement — just what you need to blow past the usual and out into "outlaw" country.

Here’s what you get:

• True ABC construction.
• "Outlaw" 6.5 mm carb bore
• Machined, high-silicon aluminum piston
• Machined, double-bushed aluminum conrod
• Dual bearings
• 360° fuel inlet
• Mixture control screw
• 11-fin, machined aluminum heat sink head
• CAD-designed, CNC-machined liner ports
• Dual-needle, screwdriver-adjustable carb
• Hand-assembled quality

The ideal engine for getting into nitro!

The 12TG is economical, easy to break in – and makes any vehicle ROAR-legal. The 12TG consistently delivers up to 14 minutes of run time on a single tank of fuel.

• Available with or without pull start, and comes with either a slide-valve or rotary carburetor.
• Steer 1/10 scale on-roaders to the slide valve carb-equipped 12TG; it's a great drop-in for the HPI Nitro RS4 or R40.
• The 12TG with rotary carb will boost performance in off-roaders such as the Associated GT2 and DuraTrax®'s Nitro Evader.
• The 12TG-P features a pilot shaft, which allows for a no-mod retro-fit into today's top-level competition 1/10 scale stadium trucks.

Competitors tend to stick with a winner — and the 21VZ-B V-Spec-T (P) makes that easy to do.

The raw power to exploit a split-second opportunity is there, tempered by the ability to fine-tune and finesse throttle control to the needs of different tracks and situations. And to help keep the 21VZ-B V-Spec-T (P) at the peak of its power, O.S. has given it a billet aluminum piston, hardened ABC sleeve for added wear resistance and a new crankshaft design that's simultaneously slimmer and stronger than any O.S. crankshaft ever made. The 21VZ-B V-Spec-T (P) — designed for first-place finishes over the long haul — from O.S.

• More power and durability. The brass sleeve is chrome-plated for performance and hardened to withstand the wear that racing action can produce. CAD-refined and CNC-machined ports smooth airflow and boost power.
• Track-tune in seconds! Increase control on low-traction tracks by inserting the 8 mm (red) or 9 mm (blue) carb restrictor. Takes only a second, but pays off, lap after lap.
