I'm talking about a DasMikro 2s6a - one of these:

And it's the bottom left pad in the image

ok bottom left connects to the 2k resistor next to it... if you can connect there it should work

as i understand it, from a damaged pad you follow the line back and run from the first component you meet closest to the pad

if there is a break between two components, a wire connected between them works...

you can get conductive pens to colour in the missing trace but i have no experience in using these and therefore cannot say whether they are any good...

I got nuthin. The receiver bound properly, but I got no motor spin. I reckon this DasMikro might be fried.

Query: 2x Vex29esc and mix in transmitter. That should work fine, right?
If I roll with that, how do I get power to the receiver? Lemons run at 5v, correct? Does the Vex29esc contain a step-down thingy like the DasMikro? I guess it has to if it supports the 3-pin receiver connector.

it sounds like it... do you have a multimeter? could see where the problem lies... test for power entering into the board, then test continuity between each component... no beep means that component is probably the faulty one...

yes 2 esc's with mixing will do the same job... just disconnect the red wire (to the rx) from one of them

i can't see anywhere whether it has an internal bec... though i saw just 1 post claiming it has a linear voltage regulator at 4.5v... i did see multiple times that it will happily run off 11.1v and someone had it running off 14.4v but with no follow up regarding life span

Okay, I'm looking at the Vex29s and... They take full lipo power in, signal in (from receiver), and output motor wires. I can't see how I'd power the lemon if I'm using Vex29s...?
... I can just grab a 5v regulator and wire the lemon, through that, from the battery I guess.
Something like this https://www.sparkfun.com/products/107
... nooo... a touch more googling and I doubt it. That said 5v bec's seem to exist, though I'm now rapidly approaching having a LOT of electronics going on in here
