The best way to make your glow engine last is to follow the recommended break-in instructions, be sure not to run it lean, and try not to force too much performance from a high-nitro blend fuel. My opinion on the best engine may be the new OS .55 Hyper for ease of tuning and a good value on a good performing engine. The YS engines have long been known for their high performance and I would suspect a better value for performance than an Align engine. If you really want some crazy power in a 600mm nitro helicopter, get an Audacity Pantera with a big-block kit an put a YS .91 engine in at .50 size heli. The one-way bearing can blow if you aren’t careful, but it’s a wild ride. Many people have run with the BBC kit, they allow .60-.90 size engines to bolt into a stock .50 Pantera.
