SPECIFICATIONS

The standard in sport engine technology, in a unique streamlined design for your nitro RC airplane!

More cooling fin area extends the life of the engine, and virtually eliminates engine seizures in the air.
Added “webbing” on the crankcase strengthens high-stress areas to help ensure that they stand up to the rigors of learning to fly.
Overall tighter needle valve fit utilizes an “O” ring to help maintain the performance levels you need
A fuel inlet that points up allows for easier fuel line access for fueling and defueling
.40 & .46 LA are also available in natural gray color (OSMG0041, OSMG0047)
include a glow plug
great for beginners with carb adjustment on opposite side of prop

The big news in large-scale sport power!

Designed for sport, but engineered for excellence, the .91 FX offers the power and user-friendly features of otherFX Series engines in a displacement fit for large-scale aircraft. The .91 FX neatly bridges the power gap between .60-size glow engines and gas engines, by offering the easy familiarity of glow technology combined with the added power that today’s large-scale modelers demand.

With its top output of 2.8 hp, the .91 FX can put a large-scale plane through its paces with ease. And with O.S.’ meticulous testing and design behind it, large-scale pilots can fly the best in long-term dependability.

Multi-position remote-mounted needle valve design offers greater flexibility and safety for the pilot. The needle valve can be positioned upright or to the side to avoid cowl modifications and preserve scale looks.
Coarse threads and an O-ring seal on the needle valve minimize settings creep over time due to vibration and air leaks, providing more flights with fewer adjustments.
Extra-long crankshaft and locknut assembly offer more thread length for better prop nut engagement and more safety for pilots and onlookers.
A lower crankcase profile leaves room for more head height and cooling fins-semi-squared head design further enhances cooling capacity and performance.
Dual bearing design includes a larger front bearing for added durability and smoothness.

Trinity Sirio S18TXPTR Nitro Engine
“…the highest horsepower per cubic inch of
any engine we’ve ever tested.” -
RC Nitro Magazine

Trinity is proud to announce that we are the exclusive North American importers for the new Sirio line of engines direct from Italy. This new line of nitro engines has been designed by Andrea Rossi using his years of experience in R/C nitro motors.

The .12 racing engine will come in “Standard” and “Outlaw” specs. The “Standard” will engine will conform to ROAR specs and feature and ABC piston and sleeve, 4 ports, turbo crank,rear exhaust and a slide carb. The .12 “Outlaw” engine will feature, AAC piston/sleeve construction, 5 ports, turbo head, turbo crank and a slide carb.

The .21 racing engine will come in an “On-Road” and “Off-Road” model. Both motors feature AAC piston/sleeve construction, 7 ports for the onroad, 5 ports for the offroad, turbo button head, hardened turbo crank, hardened car barrel insert, 3 tuning adjustment slide carb, and a volume metric racing pack-plate. The “Buggy” and “On-Road” motors are differentiated by the power bands. The “On-Road” motor has a much “harder” hitting power band and the “Buggy” engine is tuned to be smoother to help get the power to the ground in the dirt.

Now owners of the original T-Maxx can enjoy the same Sirio .18 horsepower that has been available for the new T-Maxx 2.5
