Totally ignorant about all the brushless / brushless ESC's / battery voodoo, I thought I'd ask for some advice...

I have a Esskay 400XT motor and a Himax HC2808-0980 motor.
I have a Phoenix 10 ESC and a Thunderbird 18 Esc.
At the moment, I am using NiMh batteries...but will be changing to Thunderpower LiPo's when Santa comes.

Two airplanes...GWS E-Starter and GWS Corsair. The E-starter is the heavier of the two.

So, my question...

Which motor/ESC combo would I be better off using in the E-Starter and the Corsair?

I appreciate y'alls help.

Well, the Phoenix 10 is adequate for either motor, and the Thuderbird 18 is overkill. It really doesn't matter which you use for which motor.

Oddly enough, you picked two motors that are EXTREMELY similar in specifications. The Esskay weighs 46g, while the Himaxx weighs 52g. The Esskay has a Kv of 900, while the Himaxx has a Kv of 980. Using the same battery and prop on both, the Himaxx will be approximately 10% "more powerful" due to the fact that it's designed to turn the prop approximately 10% faster.

It seems to me that the Himaxx generates a bit more power so I guess I'd stick it on the heavier plane.

I've test run the 2808-980, and it gets you almost 20oz thrust @ 36mph drawing 9.35A on 3s

I've never tested a 400XT but from what I read it is better with smaller props, so maybe it would be good with the Corsair spinning an 8x6 or similar.

How about a Himax 2808-1160 motor. What prop and battery cells, if this motor would even work. I am not too up on matching motors to planes!!!!
