Custom (very) Quark esc heatsink...

That could explain why so many have heat issues.

WOW I did a bench run of the motor, almost full throttle with 16.5 volts. The motor got so hot I could only touch it for barely 1/2 second.

The esc on the other hand never got warm at all, the heatsink seemed like it was a a couple degrees warmer than it was before i started (10 mins). I looked at the eagletree, it consumes almost 140 watts no load, running just about full throttle, so almost all of that power is wasted as heat, 140 watts is alot!

The heat spreader on the other set of FET's got about 45 C , to the touch, just a guess, but that bottom set just stayed VERY cool.

What temp would the motor be if i could only touch it for 1/2 second? I hope i never got it too hot. :013:

IIRC, you are NOT supposed to run the motor unloaded for any length of time at full throttle! It could possibly damage the motor! Just thought I'd let you know...

Bye:018:

I know, but i did let off about 10% off full throttle. To keep the rpm safe limit.

ProCharged: I JUST ordered a duratrax flashpoint thermometer for $30, just happened to be on sale too (was $40).

So what is the max safe temp for the 540C 7Xl then? Does anyone know?

Oh, and i forgot to mention. I DO have a temp probe for my eagletree, but I can't get it to read properly, wtf does 6064 mean, it's a straight line. I've tried many times, no luck. :032:
