I only have 150s, not 180s, but I strongly recommend that you consider something like a 28x14 vs the 26x16 IF you are flying a plane that can stay in the air at the airspeed that prop will produce for you. I found that for my early SN Moki 150s a 26x16 still revved my engines into overheating at the lean setting that was required to get cylinder number three to run almost all the time (burbles at mid throttle wouldn't you know...). With the higher diameter prop RPMs stayed down in the 4500s and so far no overheating. I am speaking of two bladed props, convert for three blade and then see what Dr Gotz has in stock.

Just my $.02 worth the price you paid for it.

Is the 26*14 good or can it handle even larger?
