I don't think the X Series 1800kv motor is rated for 3S but I know some have done so successfully, IIRC Dan.50 is one that springs to mind. IMO not the ideal motor for 3S but fantastic on 2S for the Crack Yak but not quite enough grunt for the Pitts. I do have some X Series 1480kv motors that are also not rated for 3S however I have run the numbers and like what I see so am going to see if one of them stands up to the abuse.

The specs for that motor say it would be good for 3S but not what prop to use. I suspect that you could use a nine inch prop on 2S to give you more power from it and your eight inch on 3S. The only way to know for sure is to hook it up to a wattmeter.

PS glad I live in Scotland we've had some great flying weather
