info on rc motor

[Norwest]

I see a rc Leopard 2730 2y for a mini sniper on OSE and like the kv but not familiar with the D or Y winds and a very mild guru to say. Info will be appreciated, thanks. I just looked on rc groups back to 2008 that 2y will take some advance while d will create heat with advance. Ok, what timing will 2y take on 3S as the rpm will be 30,000 which is close to the sweet rpm and prop will be 632. Pleasure only and fun. -5 degrees here. I first put a prop outrunner 2836-2700 with a cooler in front but these outrunner work best in airplanes where air will cool them. I went hunting an OSE and ran across the 2730. Thanks for the info, appreciated.
