davioh - No you can have 3 or 4 wires come from esc's. 3 wires means that you will have to do some soldering because the red wire goes to both the positive battery and the positive motor terminals. If your ok with soldering and just want a high quality racing esc then go with the MC800C over the MC600C.

what so "high quality racing" with the 800c? is it cuz it goes to 5 turns? cuz i run 23 stock and 11T mod and i was wondering why would the 800c be better than the 600c other than the turns number

The 800C has alot more setup features, cand handle fewer turns and has a lower internal resistance. Both are good esc's so if your not a serious racer and your not going to use the features then there's no reason to spend more for the features. By the way, why not just send the esc you have in to be repaired?

The lack of a fourth wire decreases resistance and voltage drop for more efficiency. Most four wire speedos have the red fourth wire right next to and soldered to the other red wire on the PC board. The less resistance = more power and runtime. In most cases, you get what you pay for in electronics. The LRP Quantum Comp (or its Futaba equivalent), the Keyence, and the Novak GT7 are the top of the list in this dept. There are some durability issues on the GT7. The warranty is best on the LRP as stated above. Depends on if you wanna spend 200$ once... or twice i guess.
