RE: cermark javelin II comments or input ?
I saw one at our club. It had an Evo 61 in it and it flew like it was on fire. The plane was very fast and fluid through all of the manuevers. The cobalt blue coloring scheme is really sweet looking too. The guy really liked it alot until he deadsticked it on take off and tore the wing in two pieces.
He finally realized that the fuel he was using was Byrons and he stated that most engines don't like to be inverted and use Byrons due to the oil content of it. He owns a hobby shop so he knows what he is talking about.
