This is a great engine for the gas engine user. It is not made to compete with glow engines. For someone who likes the reliability of gas and clean models it is a good step over a G26 and will fly many large models that are available. When one buys an engine made in the USA, Germany or Japan, I think they have bought a better product than Chinese, and have a product withbetter resale value. China is great at copying but poor at innovation. Their first thought is how cheap it can be made. Quality, long life and reliability are secondary. One usually gets what they pay for.
