You don't. Mine works great on the internal bec on 2&3s with a 550 motor in my 4x4 slash. It's a bit ridiculous to complain so much IMO. Not going to change the fact that you couldn't get it to work. It's a 3 amp 6 volt bec. Not suprised it won't push a monster digital servo a receiver and a transponder. If the Slovak works better for you then run it and be happy. But it's not castles fault you coulnt get it to work. Not really sure why everyone uses these high draw servos in a sc anyway. I run a 360z and it's more than enough. And if the mmpro is in an 1/8 scale well your on your own cause it was designed for 1/10 applications. Not trying to be a jerk or anything but it gets old reading how some can't get the mmpro to work when it works great for most. Novak has always made good stuff too I just choose not to run it for personal reasons. Whatever the case may be the only real solution is to run what works for your setup.
