210v2 lipos

[jonathan may]

what lipos are people finding best to use in a 210v2 shorty or stick lipo ?

Hi,

My personal choice has been shorty's for quite while now.

I made up some foam blocks so that you can move the shorty either
Forwards or backwards in the car which will give you a good weight tuning
Aid.

I generally run my shorty to the rear on lower grip tracks and to the front when on higher grip tracks to get some more steering.

I use a shorty here, running 4rm, pack all the way forward.

Shorty and some foam blocks......

It seems for most cars if a shorty is used, drivers have to watch the weight (and often add it elsewhere) to make it run as they desire. It offers a nice adjustment feature for weight balance, but the overall weight it still needed.

Unlike most cars, the DEX210 seems to have that weight already. My 210 (in SWB) was a good 100g over the minimum weight with a short pack and bulky ESC (This layout (http://www.petitrc.com/setup/durango/setupdex210/DEX210_PaulDijkstra_Arendonk20130727/bigpics/IMGP8825.jpg) weighs 1599g). I placed everything but the Rx and PT in-line with the chassis - The main reason is because my ESC is actually too big to fit in the sidepod or on top of the battery, but the nice side-effect is that as standard the weight is nicely along the centerline of the car, besides leaving space to put weights in the sidepods to change roll characteristics of the car if needed. If your ESC fits within the sidepods you can place it there and play with the front to rear weight balance instead.

And with the 210's weight your concern with a shorty is not to get to the appropriate weight and adjust the balance - it's just to adjust the balance (with position of the shorty) - So in my view, Shorty it is! :)

I'm not used to anything else, so I can't tell if it's really better. That said, I don't feel like I'd be better off with the electronics in the sidepods. In fact with the LWB chassis I use now I can even put the capacitor on the chassis instead of on the battery plate (Click (http://www.petitrc.com/setup/durango/setupdex210/DEX210_PaulDijkstra_Merchtem20140427/IMGP9773.jpg)) - and I can tell you, my ESC is like a the Cube from the Borg... it's humongous :lol: With compact electronics I can imagine one would be able to place the PT under the servo and the receiver together with the ESC between the servo and battery - before you know it you can make the car narrower than the TLR22 or Gerd Strenge's Slim B4 (http://www.apexspeed.com/doug/rc/durango/b4/durango_b4_004.jpg) :)

In theory it should make a fair difference as you are reducing the polar moment of the car, pulling a ~80gram speedo on a 1600g car out of the sidepod onto the centreline (maybe moving it 6cm?) should reduce the roll of the car in corners and also improve the response to steering inputs.

Just a matter of if i have room. Or inclination.
(Or time!)

how far forward do you run the lipo ?

I have done you some pictures showing the foam blocks i made and the various positions of the shorty lipo you can achieve with them.

thanks for the pics foams not a problem work with the stuff for a living lol when you run it all the way forward do you run any weight on the rear

[Jason A]

Hi,

When the lipo is all way forwards I tend not to run extra weight at back.

If I was running with lipo at back of the car I may consider putting either the
15 or 30mg brass weight under the servo.

running the 65g bulkhead weight at the moment
