Default Rookie Question

I just got a Brio 10 with the recommended setup: park 480, e flight 40A esc and a Tanic 1550 3S pack. I test flew it today and noticed that after the motor ran a while it tended to stiffen up a little almost as if something had expanded slightly. In other words, it doesn't spin as freely after the motor runs as it does before the motor runs. After a while it frees up again. Since I am new to electrics, particularly outrunners, I don't know if this is normal or not. Anyone seen this before?

Thanks,
Brian

Was the battery connected when you tried to turn the motor? Whether the switch was off or not (if there is a switch), there can be enough 'bleed' (i'm sure the EEs will have a better word for it) through the system, with everything off but the batteries still connected, to have a field in the motor and make it difficult to turn. I had this happen with a model of mine, had me scratching my head for a long time.

i have an e-flite 370 outrunner that does the same thing, it doesnt get hot, but after i run the motor it wont spin nearly as loose as it did before i ran it. if i come back to it in a couple hours or more, its back to being real free again. i have prob about 50 flights or more on it by now and never seen any problems, at the same time i have always wondered if it is steeling some of my amps. i also have an e-flite 450 outrunner, 480 outrunner, and hacker A30 outrunner, none of these have this problem like my 370 outrunner. i will be watching this thread also to see if anyone else knows what this may be.

That's interesting. It sounds like yours is doing the exact same thing mine is. It seems to run fine, but I too have been wondering if it was robbing some power. I have contemplated returning it to see if a new one would do the same.

im sure if you return it, the new one will not act like that. i also have a 480BL and it doesnt do it, but my 370 does, weather or not is robbing power or not, i dont know. maybe its something that e-flite has on a small percentage of the motors that they turn out. but since its a rarity i guess its not all that great to have one as opposed to one that acts normal before AND after the flight. if i had realized that this was not completely normal back when my motor was new, i prob would have got it replaced, but as i said before, it seems to work fine, lol so who knows if its anything to be concerned about?

anyone else have some input here???? please post if so.
