Mamba Max fan??

I suspect you will need the fan(s). I used a Y harness to hit the batt slot on my Rx since I needed to plug in a PT too. I cut the +/- wires from the CC BEC to the Rx and spliced in leads for my fans there. Had a couple of Integy (yuk) heatsinks with fans sitting around and used those. One already died, but there cheap and Integy, so what would you expect. 30x30x6.5mm 7.2V is what I had, and BEC is set to 6v so i ordered a couple of 6v ones to keep me going until my 3Ms come back. If you don't beat them to death I suspect they would last a little longer anyway.
