Guys, I have an old 215cc MOKI that I've owned for years, and hope to get it in the air by next Spring. I'm starting to build a large glider tug and asking about the proper range of props. I've seen here that a 32X18 is used a lot as a two bladed size. I understand the idea of limiting ground RPMs to less than 4000. My question is, should I use something different than props used on WW II fighters (32X18) as I'm not needing or wanting as much speed as the scale fighters have? The tug will weigh about 45 pounds, and largest gliders will be about the same. Does anyone have experience using the 215 to power a tug?
Thanks,
Larry Fitch
