Kidding. It's my new 55-10-32 with a heatsink from my dead CC and a big blue one stuck on. It was quite a task to split the boards & stick in the CC. Thanks NTM for the info.
Just finished it and the thermal epoxy holding on the heatsinks is curing as I type this. I sure hope I didn't fcuk up anything and that it works or else it's $265 down the drain! :D

Two quick questions, as I'm considering similar actions:
1) What does the CC heat sink look like that goes between the boards?
2) Can you detail on how to split the boards?
I think it might be time to go shopping for some poor soul with a dead one...
TIA,
John

As my Jazz controllers never get hot, I'm surprised you need a heatsink on it. Maybe because I run high voltage (4s on my 450 and 10s on my MA Razor) I don't pull enough amps to heat up the Jazz ESCs.

He lives in Australia, though, pretty dam hot there! :P

Great work Kev, i was lazy and never split the boards but only ever thermalled it when i changed a pinion so i went back to a 14T. Who needs 2500 HS anyway :lol:

Thanks Russ!
John, have a look in the pic below. The CC heatsink was temporarily placed on the ESC for reference. It replaces the middle silver plate. The big heatsink replaces the top silver plate.
I cut the 3 jumpers directly below where the motor leads are soldered on & prised that end apart just enough to replace the metal plate with the CC heatsink. Then resoldered.
Btw I used http://articsilver.com/arctic_silver_thermal_adhesive.htm to stick on the heatsinks. If you use this, scrape off the existing thermal tape off the mosfets and you only need a tiny dab on each one. Remember it can be conductive & don't get it on the pins. I ended up spreading a thin layer on the CC heatsink before sliding it in as would've been too messy to place a dab on each mosfet inside the ESC.

Just soldered on all the connectors etc. First thing I wanted to do was verify the throttle direction was correct. Turned on Tx, reset throttle curve to linear and normal direction. Turned on Rx & with spark arrestor disabled (have to find correct resistor value) plugged lipo into ESC. It didn't beep. Realised I had the jumper still plugged in, unpluged lipo & removed jumper. Tried again, tried reversing throttle. Nada!
Noticed the LED was flashing in sextuples. Checked manual, said cause: Program fault. Solution: reconnect lipo - didn't work. Another cause: loose contacts or other faults in installation. Solution: check installation and attachment & correct if necessary. If the fault persists, send the speed controller back to the manufacturer!!
Tried another Rx and even with the ESC not plugged into it at all. Still flashes the same sequence.
I think when I scraped the thermal tape from the inner mosfets I accidently broke off the corner of a tiny 4 legged chip almost on top of where the negative end of the throttle wire is soldered underneath the PCB. A bit of the leg is exposed inside the chip but not broken as far as I can tell.
Dammit, is it dead?? :( Any other way to fix this?? Don't think I can send it back as modded it obviously!

That sucks Kev, did you power it up before the mod to make sure it worked, just clutching at straws!. Have you checked all your solder joints for being dry or bridged ... again clutching! I think your cactus, if you could find a local electonic repair guru he might be able to sus out the broken chip and replace it
good luck with it, i was hoping to hear your flight report this weekend but maybe not now!

Think it's carked it too - what a bummer ! - good try though - might be worth sending back to Kontroniks for service though when I sent my burned out MOSFETSs to CC on an HV85 they just binned it and sent me a new one. I just Artic Silvered an old computer graphics card heatsink on mine and hasn't bugged out in our Sunny Coast 31 °C even on 6S !

Nup, didn't power it up before doing the mod. Should have, now I'll never know if it was dead from factory or me, oh well.
Dunno if Kontronik will fix it as seeing I modded the hellout of it??
I did have some trouble soldering the motor bridges back together. My solder wasn't very compatible with the one Kontronik used. But that couldn't be the problem.
Yeah, I shoulda just stuck a big heatsink on and left the boards the hell alone! :lol:
Damn Jive, the Jazz was meant to work until it came out. Was meant to get the Logo going now & see if I like it and order another as back-up as seeing I put in my entry form for 3D masters! Might end up competing with my T-Rex 600E's!

Sorry to hear of this. Kontronik will fix it though I am certain, don't ask me how I know! LOL
I did not do this but experimented on my own once in another way. :lol:
Just make sure to include on your letter your email that they can get in touch with you at for payment, as it will cost you a few dollars for them to get it back to the start again, not much,, less than a new one that is for sure.
Good luck man!:cheers

I bet they were using that politcially correct, no lead, Beryllium stuff - bet you weren't :)

Beryllium huh? As if my heli needs anymore power! Can you tell I've been watching too much Star Trek? ;)
Does anyone have the contact email for Kontronik so I can send my ESC to them? Cheers!

Try Mike Franz mike@kontronik.com
Good luck Kev, they were great for me in checking an esc out, didnt even charge me for freighting it back!

jrohland
I don't think 10s is considered high voltage anymore, that's regular voltage, lol !
The double heatsink mod was necessary for me because of the neu 1915-1y I was using in my logo 14. 2300 rpm, 600mm v-blades and 15 degrees of pitch added up to 120+ amp spikes. Flightpower 10s 25c 3700mah packs.
The 55-10-32 would thermal just about every flight with the heat sink on only the top fet's. No thermals at all with the heat sink on both sets of fet's.
A worthwhile mod if you need it, it's really not half as difficult or scary as it sounds.
Definitally send that esc back for repair, get back on that horse ! :D

I don't suppose you might have pictures to show how it's done...
TIA,

No, there are some on the german forums if you do some digging though.

Anyone know the German for Ozzie toasts speed controller ?
