Power, smooth running combined with low noise emission make the Irvine 25 R/C one of the best, most reliable, engines in its class.

Based on the new crankcase but featuring most of the tried and tested internals that made the original 36 Ringed engine such a favourite.

All the power of the old ‘F1’ but with lower RPM torque and better throttle response making it perfect for that hot.30 class machine.

The new Irvine Tutor 40 sets new standards for getting started in radio control model flying. The full colour instruction book assumes that the builder knows nothing and guides him through the construction every step of the way. With over 160 colour pictures to refer to, the beginner has the best chance of success first time.
