I am trying to solder a 2X2 Stacked FETS to my miniZ PCB but the black component is blocking the way to the input legs. Do you desolder the black component ( Dont know what is it called) and fix the FETS ? Seems like there is no space and quite difficult to solder without removing the black component. Please help

I always stacked layer by layer, never a pre-stacked set.

I DO prestack the FETs. The black box is annoying but I just hold the soldering iron more vertically and just tack solder each leg to the pad. It is the most difficult part of the FET upgrade for sure. Sometimes I do touch the black box accidentally when I'm doing it, but if its only for a moment it will be fine. I've done four FET jobs in this way.

ok I have managed to soldered pre stacked 2x2 FETS, the black component is quite irritating, now the car zips around very fast!!:p

Great, I'm glad it worked out for you.

Yeah FET stacking can be difficult. Its takes job after job to perfect your technique.

you need a small tipped iron and even have seen a small curved tip used, and do the side with the black thing in the way first or you'll also have the other stack in the way.
