Neil,
It's not the hyd motor that getting hot, it's the BEC aka ESC for the turntable motor. The pump motor, so far so good, i'm using high Amp (29A, 12VDC here). Instaed of inst a fan, i wanna glue a artificial blade on the BL motor body, and it will direct the cold air from outside, to cool down the whole units. Having heatsink on the BEC body would be great idea too, thx.

Maybe that's not the real trouble, i dont hv to play for >1Hr time everytime, just tried to push up to the limit here, to see anything would fall apart or break..once my Dump Truck is ready, it would be great conbination i think. I love this stuff
