ROAR make the spec ESC moves…

US rule-maker ROAR have given the clearest indication yet of their intent for a new generation of spec ESC to be used in what they call “Sportsman” racing.

Speed Controllers eligible for Sportsman Class racing must be capable of providing ZERO Timing Advance along with disabling Advanced Motor Control Functions (i.e. Boost, Cheat Mode, Turbo, SuperCharge, etc).
When the “sportsman” profile is enabled, the ESC shall indicate the profile by a unique LED (constant or blinking) while the ESC is “armed” and in neutral position. The unique visual identification detail will be published along with the ESC listing of approved products.

ROAR say they are working with manufacturers to put together the list of approved ESC’s – and it looks like that will include some of the current favourite ESC’s loaded with a new spec/sportsman profile (that locks down the ESC to zero timing, and adds the visual element of the blinking LED.
The full announcement is on the ROAR website here
It might just be worth waiting to see how this pans out – and it might mean that a 21.5 turn motor on a sportsman ESC is a close equivalent to 540, solving the two major spec class hurdles in one go.

ROAR doing it is a long way from anything happening in Australia or Queensland. Interesting it’s mainly modified drivers who think this is a good idea.

The LRP have their say on the matter
LRP SXX StockSpec – too powerful for stock racing?
It’s rumbling inside the scene. Latest speed controllers provide extreme high top speeds in stock classes. “Is that still Stock?” – this is what many racers wonder about.
It’s a dilemma. On one hand, stock drivers don’t want to pass on modern technologies. On the other, latest speed controllers provide an amount of power which almost lifts them up to modified level. For sure, the LRP StockSpec is on top at this point which has been proven by countless victories in the latest past (LRP TCM, DMC DM Indoor Sport, all (!) ETS races in this season). Its power has brought speeds to the stock classes which were unimaginable in the past. Too much for many drivers and organizers. Further on, the optimal setup of the controller varies a lot depending on different motors and track sizes. For many drivers, it’s not possible to invest such a high amount of time to find the perfect setup. This leads to completely different performances of the cars which is against the spirit of stock classes.
A simple solution has already been implemented in LRP’s SXX StockSpec which gives you the benefits of LRP’s modern technology and keeps speeds and efforts on a moderate level: the “Boost 0” mode. Using it, the motor runs very efficiently, cool and with conventional speed without power program. To make this mode easy to control for drivers, organizers and officials, the controller’s LED flashes while the electronics are active and the car is in neutral state. During a race, it’s easy just to walk through the starting grid and find out with just one look that all controllers operate in “Boost 0” mode.
This video shows how easy the cars can be controlled » “VIDEO”
The results are amazing. Radar tests led to following measurements: a Hot Bodies Cyclone TC with LRP 13.5T Stock Spec motor, LRP 5900 50C Hardcase LiPo and a LRP SXX StockSpec speed controller inside reached up to 53 mph on a long straight with a gearing of 1:4,95, operating in “Boost 8” mode. With the mode switched to “Boost 0”, the exact same car was slowed down to a maximum of 35 mph. Now it’s your choice: maximum power and speed generated by the magnificent software of the LRP SXX StockSpec or “true stock racing” with “Boost 0”.
Stop press: R.O.A.R., American association (equivalent to German DMC) has reacted and published a catalogue of all speed controllers which are regular in Sportsman Classes. Thereon you’ll find many simple controllers which don’t offer power programs, e. g. LRP AI Brushless series. The LRP StockSpec is also covered but has to be operated in “Boost 0” mode. R.O.A.R. statement says that many manufacturers will follow the LRP philosophy and develop controllers with a “Boot 0” mode that will be displayed by a flashing LED in neutral state. This will smooth the way to exciting and narrow races on a conventional speed level which supports the basic idea of stock racing.
