Cheap "high voltage" esc Quest

Sure we can make it better, and I think you right, Lutach, for smaller footprint D2pak-7 would be great choice. But I will do that if there would be demand, otherwise I do not need one for myself.

I will mod this one with irf2204 and with better soldering and cooling and we will see how it does.

Keep us posted on how it does. The irf2204 is a nice mosfet for sure. Did you make your board work with the MM brain? I have an idea of a new ESC. It will use 120 MOSFETs total (40 per phase) and the power boards will have a small foot print, the only problem that I'm having is putting the idea into a drawing to show you how it should look. I have the Eagle program, but I have no clue how to use it .

I will,
Haven't had a time, yet, for complete solution. And I am happy with last gen. power boards anyways, and as for high voltage MM ESC need to be studied a little bit more. While you in process of delivering high voltage version anyways, right? :)
120 is allot, and you meant 20 per phase, H-bridge requires 2 fet's per phase. Just make sure that pcb traces can handle this...
As for Eagle you can start from tutorial, or from examples. But at the beginners level I would recommend ExpressPCB, very simple.
Also you can just make it in paint shop and I can do the rest or somebody else...
Meaning we can start layout/project and you can finish/learn.

The guys that is doing my controllers told me they would be done this month, but I will only believe him when they are here. The controller I have in mind will use a total of 120 MOSFETs, so it will be total 40 per power board 20 FETs on each side. You are right on this one 20 per phase. The FETs that I'm basing this controller on comes in 30V and 60V, so a HV version can be made. I'll try to cook up a very detailed drawing to see if it'll make sense. To me it does, but to someone else it might not. I also have a crazy idea for the traces to handle all the power, but I'm not 100% sure it can be done. I'll find a way to get a drawing and best explanation out to you as soon as I can.
