I have a stock spartan running two 3s 11.1v 4200mah 30-60c lipos. i want to runn a metal prop. what size should i run. i was looking at some on the kintec racing website that comes up under the spartan section of there website would any of them suit my spartan.
I reccomend using the search function on the forum, lots of threads on the subject...
In short, an Octura x442 or a Prather 215 stainless steel prop will work. Make sure you take the time to balance and sharpen or buy it that way, but dont run it unbalanced or you will tear up your driveline. If none of that sounds appealing, stick with the stock one, they are cheap and work fine.
I'm running the Prather S215 on mine. I bought it from ose pre sharpened and ballenced. it works great. I've got a 442 to. I'm going to sharpen and ballenced myself. Don't go any bigger or you might fry your electronics!
