FC300A ESC Parts Information Wanted

[Alexgar]

Did you try with an external bec and motor and see if it will spin

[capnswanny]

I did, got one beep when I plugged it in.....pause.....10 beeps.......pause......10 beeps...etc
No throttle response, played with throttle settings, rev, no joy. But, no smoke yet :)

Corey, I'll send 3 of them to you. I'm not too worried about them. Fix them...blow them up..whatever.
PM me your address.

Joel, Got the Speedos...Thanks!
Looks like 2 have some failed FET's and controllers. The 3rd looked good but for some corrosion on the controller card. I'm going to enjoy seeing if I can fix these.
I appreciate your help buddy!

No problem. I have 3 others that are in use right now. After those ones failed, I coated these with liquid electrical tape. So far so good.

Did you use the.spray type to waterproof or paint on

Yes, spray on type.

Well here's my first DigiKey order:

(4) IRS2103SPBF - IC DRIVER HALF-BRIDGE HV 8-SOIC
(6) IRFS3004TRLPBF - MOSFET N-CH 40V 195A D2PAK
(3) TAJC107K010RNJ - CAP TANT 100UF 10V 10% 2312

Let's see where that gets me. These are the visibly bad components on the 4 ESC's. I'm still going to take some time to read some of the circuits and hope I don't find anything else bad. It really helps that you sent me three of the same boards. Guess I need to get me a programming card on order :)

Cool hopefully you get them all working then you can sell me one

Hehehe, and I don't have a motor or vessel that requires an ESC this size.....just planning ahead

[Alexgar]

Yea never got a chance to try one and am a little apprehensive to try one while so many horror stories floating around

[Rocstar]

I hope you can make something work. These ESCs appear to be extremely susceptible to moisture. Just a small amount of condensation under the shrink wrap would take them out. So far the testing of 3 others I covered in liquid tape in two different boats (one twin and one single) is going well. However I just crashed and submerged the twin, so we will see what happens after is all dries out.
