Oh and one more thing to add, there has to be an equilibrium.

10 cells is way too much, conversely 1 cell would be too little.

You can't say that if going from 7 cells to 6 cells worked, then going from 6 to 5 will work. Using that argument, you'll be going from 3 to 2 in no time!

It all depends on how you set your goalposts. Are you after best laptimes? And are other factors (eg tire technology etc) evolving as quickly? We see F1 and next year Moto GP having a reduction in motor size (to slow them down - although for different reasons; safety). But they can compensate by refining fuel technology, tire compounds, aerodynamics etc. RC will never advance too quickly in the exogenous factors.....food for thought.

the whole country should change to five cells because you got better lap times with your setup at your track? Did you even win, or did the fast guys with six cells beat you anyway? How about this, you solder on a extra battery bar so you can just use five cells when you want to, and the rest of us don't have to change just to benefit you at your track? The Roar rule is that you need to have 6 cells in your car, there is no rule on how many cells have to power the car, so the current rule of 6 cells should be sufficient for everybody.

I also did go up two teeth on the pinion which is faster right ?

faster? no your getting alot less puch from dropping a cell and even less punch from going up 2 teeth pinion.

you may still be going the same top speed along the straight, which is not the same as going "fast"

Here you go Wild Cherry, your 5 cell pack is legal and always has been, good luck...

8.3.13 Unless a lower number is specified in the class requirements, a maximum of six cells is permitted in any vehicle motor power pack used in ROAR-sanctioned competition.

I prefer to use End Point, Exponential, and Throttle speed adjustments on my radio, with throttle profile and current limiters on my speed control, and different motor winds and gearing to make my car more drivable and controllable for some tracks that require less power to be competitive.

Thany you all for your posts ...

Mason

I only race modiflied ,I never race stock or 19T...

Only change with set-up I`v made so far is to lower my ride height due to less weight...

X-5

To much power ?
Todays motor`s couple with the new 4200Ib = more than anyone can handle...
I`v tried smoother motor (less power) did not go faster...In fact (I went slower)...I got to out gun those with 19T or lose...

Scrubb

Not trying to tell everyone to go 5 cell ...
Trying to tell everyone 5 cell is lighter and couple with a fast motor you go faster...

Adjust your endpoint ? I`v tried, you will not achieve a good power band as the top & botton end power is fudge up when you do that...

PITTB

A 5 cell 2 star is as fast as 6 cell 1 star , agree ? BDW either one is still fast...


Coming soon ...
Testing 4 cell and a 3 star combo....

some guys were running with only 5 cells hooked up at the last 2wd buggy worlds, to take away punch, they had 6 in the car, but only 5 hooked up,

one thing thouh, when you say it gives the car more grip, thats not true, it gives you less punch, and less wheel spin, but not more grip,

a lot of the guys at the worlds did only use 5 cells but kept the 6th cell in there to keep the balance and weight distribution the same.

Also as well as using 5 cells they changed motors to lower winds because of how different motors motors react.

Personally i prefer the feel of a 10*2 running 5 cell to the feel of a 13*2 running 6 cell. Both have similar straight line speed but the 10 easier to drive without lighting up the wheels.

O--no !!

When you try you will learn , lots more grip , maybe like 20% ?


I had to adjust my back end up a bit compared to 6 cell, to get the car to free up and steer....

Lots more grip ....biggest change you notice when you try...

Ok how does going to 5 cells give you more grip? It only feels that way cause you don't have the punch. There is no way that dropping a cell gives the car more real grip. Unless you replace the cell with a water bottle to spray the track as you drive over it...

Dave , lighter car = more grip ...
more side bite mostly ....

go ahead put another 70 gram`s in a 6 cell package , you will have even less side bite and grip because of the extra weight the car will have to control..

This is why 7 cell mod waz slower than 6 cell mod...

Dude, no, slow down. Your car FEELS like it has more grip because you don't have the punch. Your not making anymore grip then what you had with the 6 cell.

5 cells would be less weight transfering slower, which would give more grip. There is truth to that, just needed to be put in perspective.
