I've had my eye on it but waiting on black filament...any day now.

Yeah I hate turd tracks... 
Never worked with brushless motors so have no idea about controllers. For brushed I make my own using the LM298 chip, can handle 2A.
Let me know how it turns out, I want to make one too. I've got some geared motors in the parts box that I've been looking to put somewhere. (I know what you'r going to say...don't go there)

I'd hate to be the one that had to clean up. Sh*tty job!

And that's exactly why I prefer cats. They don't poop on the floor and get along with Roombas[^].

Printing was no problem at all. It has only few parts, which you have to print 2 - 4 times. They fit well together. It has no room to install bearings for the moving parts. Too bad, because model helicopters are mostly made of bearings and I have enough in my parts box. Also, I'm going to modify the side pieces that hold the cogs and the tracks. Instead of gluing them, I will drill some holes and install them with a few strong screws. This way I can always take it apart and repair it.
Fir the motors I have now found this[^]. A 30 amp ESC is way too strong for the robot. It could easily be used with the stronger helicopter motors. 10 amps would be plenty and the ESCs are much less expensive (as are the motors). I will look for both in the parts for quadcopters.
When I come home I can post a picture. But be advised: It's has not been painted yet and is still completely in turd.

Brush-less motors I have only used on one occasion and found they ran much hotter than brushed. So I'm guessing the current draw at start is higher (they were used on pulsed loads?) I have always used LM298's and never had an issue

Really? The ones I use[^] don't run hot at all. Right after landing they can be touched and feel only slightly warm. Under the helicopter's canopy there is not really a strong stream of air to cool it. Just look at these values:
Quote: Input voltage: 22,2V (6S)
Max continuous current: 115A/195A (5sec)
Max output power: 2550W/4330W (5sec)
KV value: 960KV
Stator Dimension: 4230
Stator Arms: 12
Magnet Poles: 8

Well this to drive spindle in a test rig with not much air flow in a sealed chamber. So not really a fair test...

Sure, but I don't really see a reason why they should be hotter than regular brushed motors. They also just have coils and magnets. The big difference is that they have no brushes that can wear out and therefore last longer.

I've got an invitation (supposedly VIP) to come and meet 15-20 companies to see if I can have a new carrier with one of them...
Anyone has experience with HackerX?

I've had the invite as well but never went. I'm happy where I'm at.
