Which is faster...........

[jodart73]

.............stock titans on 14 cells with the EVX, or two 14 turn doubles in parallel with a super rooster on two 7 cell packs in parallel?(8.4V)

[Josh Haskell]

wat do u think

[outkast187]

8.4v with weaker motors or 16.8v with more powerful motors.....hmm

[DaShogun]

An extra 8.4 volts? titans on 14 cells....

[summit_rules]

because the emaxx is so much heavier... i think the titans will be faster! i might be wrong, but you i think need a lot of torque to move the emaxx and not all that high-rpm stuff that those low turn motors offer.

[Whiplash]

Titans definatley faster, and way more torque.

high summit

[outkast187]

weight has nothing to do with it, if it was a pan car the titans with 14 cells are still gunna be far faster.

voltage is power
torque is fast

RPM is also fast, but with enough torque gearing will more than make up for it.

and if the 14 doubles were the same voltage, they would still be slower.

In general it is wise to go with higher voltage rather that with current (Amp).

Power = voltage * current. The higher the voltage the lower you can go with the current at the same power. Electrical resistance increases in proportion to the square of the current. That means at double the current the resitance in your system is 4 times as high. The lower the load (current) is on the batteries the higher their voltage.

You run faster, cooler and more efficient if you increase the voltage and bring down the current. Of course this is only true if you also gear it down to adjust for the higher rpm.

Of course brushed motors become less effective once they exceed a certain rpm, so you can't go too high.

Orca hit nail on the head.

To drive his point home, consider that power lines carry juice at very high voltage but very low amp so the juice can be transferred from power station to you house with as little loss as possible. BTW, the voltage is stepped down and amperage is stepped up just before the juice enters your house!

The thing is, I have an old school Emaxx, and the VX-12 was giving me problems, so in went a Super Rooster, and a pair of 14T doubles (Speed Gems). Then the maxx sat for about 3 years, because my hot rod was soaking all my attention. This winter I started messing with the R/C stuff again, found out about the recall, and sent in for the EVX. I have since installed the EVX and old Titans, and I'm not quite sure if it is faster now, but it definatly has more torgue. I,m looking to speed up the old E just a bit, so what are your recomendations othe thatn brushless(less expensive)?
