Default Tribunus 200a and temp

Its been over 100f degree here in northern California and I I was flying my logo 700. After I landed I seen where I put the hot glue on the capacitor were melting from how hot the esc got.

Just want to make sure that this ESC will handle the heat, this was on the newer version 52.

I was getting the warning sound that was 105c that's 221f that's pretty hot to me and not used to a esc getting this hot. I do use a cattle fan to help.

I think the max is 120 degrees Celsius. You are getting close.

You said you have a fan installed ? Maybe you need to open up some holes in the canopy for ventilation.

Is it geared correctly for the rpm you are using ?

Using Scorpion Modeling Mesh to increase cooling for your ESC and motor on your RC Helicopter! | Scorpion Power System Blog

I would make a summer canopy.

I used shoe goo on mine. I don't think I would ever have that problem here. It doesn't get that hot. lol

Something sounds wrong. Maybe its the motor and 14 poles and I'm assuming you're using 12s, but I'm running the 200a tribunus on a Max V2 at 2300 rpm with 720mm blades and 14+ degrees of pitch with abysmal collective management and I can't get past 67 degrees Celcius.

I have 3 Tribunus 200 setups. I have to run a fan on all of them or I can hit the thermal threshold on a hot day. The ESC runs hot, and IMO a fan is required.

For the hot glue on the caps, I used the high temp stuff and it's held up through brutal ambient conditions.

62C is the hottest my Tribunus200 has got in my Logo700 so far. That's flying on a 30C day. No fan. Also used ShoeGoo here. Works great and if it melts off, you got bigger problems because your ESC is probably on fire!

Would someone mind posting a pic of the hot glue/shoe goo mod? Are you running a full bead around both capacitors?

Thank you.

Glue top and bottom so they can't wiggle. Without glue the caps fall out in just a few flights.
