Sport Jett, Novarossi, Picco, etc. all make high performance engines. True. But they don’t need to be used in racing applications. They’re popular with 3D because their carburetion and performance/reliability are so impeccable.

Sport Jett engines are just that - sport engines. The LX series engines are high performance engines based on racing heritage. They are one step below racing engines. The L series engines on the other hand, are torque engines. Designed for larger props at lower revs. The difference is the Jett will turn the same prop faster and smoother than any OS or ST engine or about any other sport engine of similar or same displacement.

Email Dub Jett and give him your specs/needs and he will tell you what engine you need and how much it’ll cost. He builds to order. No other sport engine is made that way.
