Anybody else been using one of these for awhile? Mine has been cutting back to 1/2-throttle about 5min into some outdoor races (not LVC: 2 different lipos come off between 25%-35% full) so it may be heat - but my other ESCs run fine in the same conditions + motor. Fan is mounted.

Also, many times when I first plug in the battery the ESC immediately starts beeping like it's going into programming mode (but I'm not touching the power switch). If I unplug the battery for 5 seconds and try again it goes away. Just strange.
