Noooooo... castle turns to the dark side....

Agree 100% with Kieren...

My comp Mini uses a 7955 on 6v, 22 uses a 7950 on 7.5v and the Super 7980 on 7.5v...

For crawler I actually use a BEC per servo i.e. the Super actually uses 2 CC BECs...

Geesh, I only have a 7950 on my 5T conversion.... well we'll go with what I have now, and will swap later as needed. :)

Almost the same, except I don't have a mini, and I'm thinking of going 7980 in my new 2.2. But I think 46kg in a what will be 4-4.5pound rig is a bit much


The MMP will be a good alternative, it's quite popular with the losi guys who have to run 17.5-21.5 sensored brushless on 3-4s just to get enough power through the worms and out to the wheels. If your only going to use it in a crawler, the 1s version might be a good alternative. No fan or internal bec and the nice solder posts, make it perfect for crawlers. As you should never really see the fan come on in a crawler and the internal bec is only adding weight. The only disadvantage is if you chose to get a HV servo and run the bec direct to the servo, as some receivers don't like more than about 7v plus the amp draw isn't to good for them either really, you can't use the internal bec in the ESC to run the receiver. Because there is none. Oh and if it's going in a crawler, a bec is required, no question asked. Internal becs in ESCs don't like servos being turned without any forward motion of the car.
