What is the preoccupation with dual brushless motors lately? Running two motors won't necessarily make the truck go faster. Especially considering that you are talking about running XL motors with only 12 cells each. The motors won't be turning very high rpms and they'll have to be moving all of that battery weight.

Perhaps a better way to go about it, with the equipment that you mentioned, would be to run a single 7XL on 15 or 16 cells, depending on what your MM can handle. I have one that will do 5S lipo very comfortably.

I will not run more than 12 cells through each esc. The limit is 12 cells (3 lipo) for a reason. Yes people have run more that through them, but my experience with overcelling speed controllers is that while they may take the extra voltage at first, eventually the speed control will fry. Besides, assuming identical motors, 2 motors on 12 cells will be more powerful than 1 motor on 15 or 16 cells. In addition having 2 motors compared to 1 motor means each motor will have half the torque load, and will heat up less.
The reason dual brushless is an attractive idea is it allows a person to step in to the world of high powered brushless at an attractive cost. A user can purchase a lower power brushless at a relative low cost, and then when deciding to add more power, the user can get another one of the lower power lower cost brushless systems, run them together, and have a higher powered system. The idea is that running 2 low powered systems have the power of a high power system, and the user does not have to spend a ton on a low power system and a high power system, when the low power system will be placed in a box doing nothing. It is a much more cost effective method
In my case, I am going straight for higher power, but I am going dual mamba maxx because I run my truck in many different conditions, and so my application demands the use of the mamba maxx's computer tuning abilities.

Besides, I do not think 1 XL can reach 60 mph in an e-maxx.

Oooook, sounds to me like you need to do some research.

Furthermore, I'm not sure if I really like your tone. (maybe this is just me?) You come in here asking for help, then you basically tell everyone what to do. :032: This is generally not a way to ask for help. The folks here are VERY knowledgeable and will help you out. You plan has some major flaws and displays a lack of understanding of BL systems and how to plan one.

Your main point seems to be cost, but you can do what you want even if you buy a Quark and a 10XL, and you'd be saving money over 2 MM systems. However, you want to do it with two MM's, so good luck with that.

One last thing, your "make money fast" signature is pure and simple spam. You might want to remove it before a moderator does it for you.
