Default GWS ICS-480 ESC with an Electrifly S-600 motor?

i just finished my great planes spectra kit. i want to save some weight so i decided to use an ESC instead of the crappy included MSC. would my ICS-480 controller work with the Electrifly S-600 motor swinging a master airscrew prop? the motor came with two fuses, a 20 amp and a 25 amp. they included the 25 amp incase you use a 7 cell battery. the ICS-480 is rated at 15 amps continuous and 25 amps max. would i be safe using this ESC? or should i just save more money that i dont have and buy a 30 amp?

It's a 25 Amp burst rating, which means for short periods of time only. On a stock 600 can motor, the Spectra is going to require long motor runs to get up to altitude, and the can motor is going to draw 25 Amps easily on 7 cells with a 7x4 prop. This could be mitigated some with a 6-cell pack, but then you'll be down on power by about 25%.

The smaller GWS ESCs are under-rated, but I don't know if that holds true for the larger units as well... I would personally run an ESC rated for at least 40 Amps, myself.

While I can't condone or encourage you to try it and see if it works, that's certainly an option to consider, especially if money is tight and flying time is short. Make sure you use the heat sink, if it comes equipped with one.

thanks Matt! i just tried it out with my "test pack" hehe. its an 8.4V GWS $10 special pack that i use to test stuff like this. the battery got super hot(of course with that big of a motor) and the ESC just got warm. i do have the heatsink for the ESC, its just not put on. i will stick it on there. i didn't seem like it was pulling many amps at all, though i know it was pulling at least 15.
