How hot should a stock Guai 425(1500kv) motor get? I was just doing some hoving in the back yard after getting it set up and when I touch the motor after a 4 min or so flight it was really hot(did not leave my finger on it for more then a sec). The battery is barley warm. Throttle curve is 100% all the way a crossed.

Gearing is
15t Pinnion
50t front main gear
19t oneway
(I believe thats right)

IS this OK whats the deal with this?

...Most , if not ALL Stock Gaui motors will run hot...my 1100 did and so does my 850...
I have changed to a Z20-980 for my mid boom -500 and will change to the Scorpion 4020-910...when i get a new CF or Fiber Frame....
Z20 ran cool today but outside temp is mid 70's....Will see when it is 105 this summer.

Is this something I need to worry about or is it fine?

...Not to worry, they are fine.
I read they were wound a bit "off" and get hot. been running that way for a long time.

I wouldn't worry about the motor temps. I use a Z20 in my 425 ad a Z30 in my 500 and they run very cool. I use a stock Gaui motor in my 550 and on warm days it comes down at well over 200F. I have been flying it for 3 years and it still works fine.

Thanks for the info guys! Seems like people really like these gaui helis. I'm just getting back into it after being away from the hobby for a few years and there is a lot of new stuff going on thats for sure.
