1.8 engine / hop ups / max airplane weight
 

Hi guys,

A friend of mine just gave me a 1.8 trimmer, the brand is "Weed Eater", the whole thing seems very light, I'm sure once I trim all the escesive weight off, things should even look lighter. I have a few questions: What prop size is recomended, what is the maximum size/weight airplane for it. And, is there something I can do to improve performance?


Thank you
