Nova Rossi .15 fx Prop size ?
A while back i perchased a NovaRossi .15 fx It has 8 ports and claims 33'000 rpm's (I find that hard to believe with a prop). Anyhow I have tried 8.4 and a 7.5 and i just cant seem to get this engine up into the power band. In the box and instructions there was no info on the prop size's recomended for this engine? Thhere must be a magic number to make it scream like it should. I have other Rossi and NovaRossi engines and they all scream Bloody murder with average size props. Some words of wisdom will really help out! Thanks ..........Ron
