That is one nicely built shiny machine!

Well, I got it wired up, and it worked!.... but then the dasmikro decided to fall apart (one of the signal pads just fell off the pcb), so now I'm in a desperate rush to get a new drive esc. Damn cheap junk.

Does the Dasmikro have pin-through-hole or surface pads for the connections?

I'm guessing looking at the pictures that it's surface pads, it's easy to mechanically stress them (e.g. pull on the soldered wire), then the track comes off the pcb. Is that what happened?

I'm guessing appropriate application of heatshrink might be a good solution. What do you think?

(NB: My dasmikro is on its way from China, I hope it gets shipped out before the Chinese new year)

It has surface pads, and the pad came off, (just the pad, it didn't bring any of the rest of the trace with it). I do wonder if maybe one of the wires got knocked in my parts box, I soldered it up for initial testing last month and didn't notice anything dodgy, and the rest of the pads seem ok.
Probably a good idea to go careful when soldering and heat shrink ASAP to provide some protection.

Well, those NanoTwos turned up at the right time, and esc panic was short lived (cheers Shakey and Rory).
Got it all wired up and bodged a cereal box lid so I could get some spinner fine tuning in...

...and initial results are very promising, the weapon is only very slightly unbalanced, it's fine at low speeds, gets a bit buzzy in the mid power range, but then smooths out high up. This is something of a miracle given it's handmade and I was basically balancing by eye, Yay!

Other good news is that gyro issues are effectively non-existent even at full throttle, so I'll probably use it fully cranked up at all times. I was a little disappointed that it couldn't gyro self-right, but i'm sure better maneuverability will be more useful is most situations.
The only downside is that even with the card top it's 149g, so I've got some weight to cut to get it to 150g with the planned polycarb top.
