edit: i got the picture (i just realized this is the first picture i have posted on this forum)



sorry for the crappy picture. it was taken with my phone with poor lighting.

there are brownish-black spots on 2 of the 3 caps. this is the only esc i have ever seen that has caps that are in a space like that. it would be very hard to replace caps like that.

Is the brown stuff on the caps leaking from the slits on the top,(can't really tell.) If it is and usually a cap electrolytic will pooch out at the top or start to seperate from the bottom, or just leak.

Adding the caps to the input isn't going to help if that is the case you will need to replace the 3 mounted to the board, Shouldn't really be that hard. Each cap is in parallel with each phase not the input. The Mamba Max is setup just like that. I'll give you $10 for it.

there are a few problems with replacing the caps. i don't know a safe way of removing the old caps, and the new caps need to be a specific size. otherwise, the two halfs of the esc won't mesh together right. i'd be willing to pay $15-20 for someone to repair it for me.

Send me a PM, the parts and inbound shipping is going to be around $12-$20, unless it's something I already have in our stock, or around the corner. I'd like to see one of those VXL's

Edit: And I wouldn't run it until it's fixed.
