You pretty much answered your question. You were paying attention. Good question, and for many others.
> Use a Fan "Mount" and fan...and not a Heat sink.
> Get a temp gun. A given.
Dam, since you are in FL dude.
> ESC when overheated will go to Thermal shut down, rig will stop in its tracks when it does.
Internal temp ESC threshhold is
212F and shuts down.
Externally that is usually 160F+ external temps read with any Temp gun. The ESC light will Flash
GREEN steadily until it cools down and the ESC will re-initialize. Let it sit there and allow the fans to do their job. Confirm with you temp gun. Then bash on. Usually does it.. Consider Cool downs after checking motor temps
The motor is on its own, It can read
Externally, well over 150F-200+F. NO Good.. Have a temp gun in hand to check things after a few minutes. A motor cannot sustain temps of 212F for long. Internally, the Armature will delaminate, come apart and lock up. The Neodymium Magnets will weaken considerably from the 212F+ heat as well. A well maintained/lubed motor can sustain 150-160F temps no problem. Keep it there. That is your Max. temp target objective. Any higher and you are on your $own$ there.
>Might just have to gear down with a smaller Pinion for summer heat. Commonly done, if you can't get Temps under control with a fan.
>Also, turning the
ESC's Punch setting down will help control heat, lipo will stay cooler also. As well as the ESC and motor. A win win 99% of the time.
>Clean and
Lube the motor's BB's frequently with a High temp synthetic oil. Heat will destroy the BB's . Consider Ceramic Motor Specific BB's when the stocker crap BB's do wear out. Just catch them in time
before they explode on you. Or the Armature can get destroyed. Ceramics will run cooler. Most any BLX Motor can and should last for many many years if you are on top of them, maintenance wise. No need to keep paying $40.00 because it is abused beyond use.
> Consider an Upgrade ESC fan. Mod the ESC by
removing the ESC's shroud altogether. Just place an upgrade High Speed Fan directly onto the ESC's Heatsink. How I fly. Works well. Much cooler IMHO.
My temp gun doesn't lie.
A Temp gun is your friend, if Temps really matter to you and your wallet also.
Having 2, also affords some failsafe redundency. Fans can and will fail at some point. I eat 3-4 fans a year roughly. I have many rigs here. Just Normally happens with bashing use.
