RC heats up when charging

[nonflyingbrick]

When I charge my P3A RC with the 57W charger the RC heats up on one of the right corners, presumably where the RC battery is. It seems to heat to around 40C or maybe more, even when the room is around 22C. I'm concerned it's going to slowly eat away at battery capacity if I let it charge at that temperature. Should I care?
I think I'll put a fan in front of it, or set a timer for 25 minutes when a fan is not available.

Since the Controller battery lasts for many flights anyway a slight drop-off wouldn't make much difference.
Also around 40C is probably no big deal when charging.
Having said that I haven't noticed any heating up (though have't particularly checked)

I will check mine the next time I charge it. Like 4wd, I have never noticed it getting warm, but have never really checked. I most times put my remote on to charge before I go to bed.

The battery is actually along the bottom 1/4 of the RC in the "as you use it" position.

Thanks. Maybe I can relax a bit about it too
