Irvine 39 ABC R/C Helicopter
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.
This engine develops so much power that it is really only suitable for the later, larger .30 class helicopters.
Brand new components and extensive testing ensure that YOU will be the only limitation in its performance!
