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
