Anyone can make a big bore 1.00 engine with lots of power, but only Evolution can make one that’s simple to tune and a cinch to start. The new Evolution 1.00NX is that engine. It shares the same footprint as a .91 so modelers can apply it’s hassle-free operation and incredible power to most any .60 to .91 airplane and enjoy the kind of spine-tingling vertical performance that’s downright addictive.
