That doesnt mean anything....If that were true then the people running 22's and RB6's with the esc behind the battery wouldnt be legal either. From what i have heard / understand you cannot secure anything into the battery tray via screws....you can however servo tape, velcro, etc mount an esc or receiver in the battery tray and be fine.

This rule was made to eliminate a car manufacturer from designing a car that only fit batteries of an odd shape (lets say a triangle), and then being the only company to make this triangle battery. Thus if i wanted to switch from a 22, b4 or rb6 to try out this other car i would not be able to use my current standard/shorty packs and would have to buy their triangle shaped batteries. This was done to keep costs at a minimum for racers, the electronics can be swapped from car to car....so should the batteries.

So why were the AE drivers forced to use a shelf if they ran inline?

Who said they were forced?

Maifield ran everything in the tray at Cactus.. I've got the ESC in the bottom of the tray and love it, car seems to corner flatter than with it up high on a shelf. Maybe some drivers prefer that extra roll?

Hmm, I saw somewhere that they had to run a shelf if they wanted to do inline. I believe it was in this thread somewhere.

It is a good tuning option to have, having the esc higher will create more roll and weight transfer. I have seen some of the TLR guys running their esc behind the battery under the mount on higher grip tracks.

That may not be neccessarily true. Cactus is not a ROAR race, it does use select ROAR rules though (mainly with regard to motor/battery approvals). You would have to double check with a ROAR official before heading to any ROAR sanctioned race (regionals, nationals) to be 100% sure.

Thanks for clearing things up :nod:

I was under the impression Team G thought Associated was mandating where the drivers could run their ESC's... as far as ROAR sanctioning, not a clue. ROAR Region 7 is virtually non-existent, and none of our local or regional tracks adhere strictly to ROAR rules, just weight, dimensions, and battery/motor specs. So, I'm in the dark on that.

In regards to ROAR rulings on the ESC positioning, I have not a clue.
:smile:

No, no, no not what I meant. Sorry if I confused you :lol:

Hopefully you can understand that confusion.

Anyway, running in this configuration has been really good on high bite indoor clay and astro-turf for me. Car corners flatter and seems to react quicker, a lot more comfortable than with the ESC in the standard position or on a shelf.

At the 2012 Roar nats(which I attended) you could not mount the esc in the battery tray. If you were running a shorty pack you had to be able to remove and fit a standard pack in without modification.

Previous to the event Cav and a couple other local AE drivers had been testing inline but on a shelf. They opted to run a standard layout for nats though. Of course since Cav has seen something he likes in the shelf setup and continues to run it.

I expect this rule to possibly change a bit this year but who knows. The basis for the rule which Matt mentioned is a very good reason.

When I ran the nationals last year ROAR had some issues with my battery configuration, so we had to go through the rules.

The car has to be able to fit a battery of maximum dimensions when presented to technical inspection. Max dimensions 139mmx47mm.

The only thing that can take up the space to run a shorty battery is battery foam and it cannot be attached to the chassis.

A saddle pack is a battery of maximum dimensions because they measure the legality of them end to end. But orientation in the car doesn't matter.
So lets say you have a 22 or an RB6 with the ESC and/or receiver in the battery area and a shorty pack. And you can still fit a saddle battery of max dimensions in the car with only removing the shorty and battery foam, then you are legal.

The B4's battery tray is only around 150-ish mm long so there is only about 10mm to mess with as far as putting things in the battery tray.

Maifields car at cactus was not ROAR legal. But cactus does not conform to all of roars rules so he was fine.

Associated's press picture with the receiver in the battery tray is not ROAR legal. Unless that is a really small receiver.

Rule 8.2.3
All chassis in all electric classes (except those specifically noted) MUST accept batteries up to the maximum dimensions allowed for its application. The legality of a chassis will be determined as presented to technical inspection. Chassis that require a configuration change, and/or a modification to fit a battery of maximum dimensions will not be considered legal, and the racer will be disqualified. Foam blocks/spacers are permitted to secure any size battery in its position, but the aforementioned spacers may never be attached to the chassis. The only exception is 1/8 off-road where it’s common to use two battery packs to achieve the maximum 4S configuration, or to use a single 4S battery, which has a different specification. Only under these circumstances will the fitting of either configuration be considered legal, but the production chassis must still conform to batteries of the maximum allowable dimensions.
