Default Power limitations for GWS IPS

Hello everyone. I'm trying to select a the best prop for my engine. Can anyone tell me the power (watts) limitation for the GWS IPS motors? And also the GWS IPSD motors. Or better yet, can anyone tell me how to determine this myself. Thanks.

GWS provides performance data on their website. www.gws.com.tw.

I think the limit on IPS motors is around 2-2.5 Amps. IPSD is just two IPS motors, so each motor has the same limitation.

I have a couple of the ips motors. I use a 5 amp esc and a 7 cell 400 mah battery. With the optional heatsinks I can get about 15 min. flights on a slowflyer.

It will last forever on 2 amps, 2.5 amps will shorten it's life but still be reasonable. I would not push it farther than 2.5 amps.

I've heard that 2 amps is the magic number for these engines. But am I misunderstanding something that I need to keep the watts down too? For example, 7.4 volts at 2 amps is much different than 15 volts at 2 amps... Can anyone straighten me out here. Thanks
