Would twin brushless setup with dual MMM's work withmy set up?

Heres what I come up with a 1521 1d question is with my high gearing will the esc handle the load. Notice I only used 3v as the voltage because nic case told me to use that figure. The the only reason I was going with 2 2650kv combos because I know they both together can handle the load splitting the load.A mmm can handle 100amps easy so 2 can handle 200 amps easy also right?

Understand this is not going to be a stock g-maxx chassis truck its going to be lowered,narrowed, lengthened and lightened with custom made tires for high speed.The drive lines are going to be titanium and steel. Still working on a good aerodynamic body though ,any sugestions?. I plan on running this at the ISC event here in california 15th of november. Hopfully break the current ~70mph record, I am shooting for a 100mph. we'll see

Yah, well he didn't realize not all batteries are the same. If you have a G3 pack for example... it will do 20C discharge @ 3.7v/cell, so if it's a 5000mah, that's 100amps. I don't think you will be that much, so the voltage will be at least that value and higher.

-not arguing-

scales and graphs and numbers are cool and all, but Nic Case holds the world record for fastest r/c, and was backed by neu(yes neu batteries too), so if he says figure 3v/cell, I would figure 3v/cell

-still not arguing-

but it has been a while and battery tech has come a long way, better make it 3.35v/cell

If you are stuck with 6s and the MMM your last setup seems to be the way to go. You may be near the limit of the MMM.

I'd go for a 1600/kv ish 1521 (or even 1527, go big!) and a 12s plane esc. They have drag brakes, your vehicle will stop! The CC HV110 is the boss, but a hobbycity "turnigy" unit has been proven to work well.

although the braking requirements of the ISC may not be met.

With 6s you'll really be pushing all of the components.

Biggest problem is the gearing I am limited with the g1 maxx tranny.That why I an going with a higher kv motor. I really dont want tire spinning or wheely torque. I want a gradual ramp up to the 100 mph barrier. I wish mike would get those center diffs out so I could get one, it would solve alot of issues. Why dont you let me borrow yours harold so I can break some records. The car does have to have brakes I believe in the ISC event.
