Default RC Restrictor Plate

Saw this on RedRC. With all the talk about motor legality I thought this was interesting. Not sure if it will take off...





"C.Andy’s have produced this AHA race management system for clubs and event/series organisers. The system places a small circuit board between the LiPo and the ESC which limits the electricity delivered to the ESC. The amount can be easily programmed by the organiser and easily checked through the use of LEDs. If the racer uses too much power the system will blink red and the driver wont pass post race scrutiny. The idea is to equalise the power from different ESCs, batteries and motors for example if you are using too much timing, you will use more power."

I don't know about this.
  • one place it says it "limits the electricity" delivered to the ESC and in another it says it will blink if you use too much
  • If it is placed between the ESC and the battery, it is measuring power consumption of the total system (servo, BEC, power loss in the ESC, fans....) not just the motor.
Not that I am for such a thing, but it seems to me a better way would be to monitor/limit the max RPM from the motor sensor and dictate a FDR for a race.

Just went to the C.Andy's website and found some more information (see below).

Seems this measures the total power used by the system over the course of a race. No accounting for warm up laps or a clean driver using less power etc.... Kind of like taking us back to the days of NiCd racing where you had to manage your power use strategically.

++++++++++++++++++++++++++++++++++++++++++++++
The new race management system for your RC car event.
Are you organizer of stock or blinky class races and not happy with the esc/engine system?

Do you have your own racing series and you want more opportunities?

Do you already hold races and want to improve for more safty?

Or do you will do an event and you don´t have so much assisants?

Then here is your way to have a safe, equal opportunity and contemporary race at a high level with less personal power.

The AHA race management system by C.Andy´s.

The visual presentation of fixed parameters is the key of the system.

A chip between lipo-battery and esc makes the measurement and presentation possible.

The system is usable for 2S, 3S and 4S Lipo akkus.

Before starting a run, you can see by a green or red shine LED lights if the used battery has a voltage (> 4.2 volts) per cell.

After the run, you can see if the battery has a dangerous low voltage (<3.1 V), represented by a green or red shine LED.

The highlight and thus really new in the system is the possibility to setup a power tank for each driver.

Like a nitro car- every driver has the same tank volume- you can choose which quantity of electricity have each driver for a run.

It does not matter which engine is run with what timing.

It does not matter if the driver is use a power program or not.

It does not matter which voltage level your battery has.

For everyone the chances are the same, because everyone has the same quantity of electricity.

The system does not intervene into the driving behavior of the car.

You can individual adjustable the electricity volume for your range and class.

Without an additional instrument and without removing the body, it is possible to perform a quick and correct technical inspection.

Only you choose which values are displayed by the system.

Only you choose which tank volume is available for every driver.

Only you have the software to make changes at the system.

Use your chance to reach the next level for your race event!

And it will still make no difference to who wins. With this sort of system, choosing a servo that draws less power will give an advantage.

Limiting RPM or top speed will not even the field unless you can also give everyone an identical acceleration curve....And it will still make no difference to who wins.

If this takes off, it will fuel an electronics war. Everyone will be searching for the most efficient esc, motor, servo, car, bearings. Tuned/dynoed handout electronics and cars/tires are the only way to have actual control.......and the best will still win.

This is a shit idea, allow me to explain:

In RC racing there are many losers for every winner. You didn't get outspent, outlucked, or outpowered by the winner, you were outclassed. If the other guy can build more horsepower than you can, and that powers them to victory over you, that makes them the better racer. Slowing down all of the cars won't make you better, it will be an equal handicap and everybody will go slower, but the finishing order will almost certainly be unchanged. Boost was killed because the slow and out-of-control saw that as the reason they were losing and out of control, now more restrictions on motors are coming because the slow believe they are losing because their motors are inferior, next will be the battery restrictions, and this appears to be the first form of that.

Restricting the cars more and more will just make this hobby more onerous. Building a fast car is part of the deal, and if yours is slower than the guy you pit next to and they're not in violation of anything you will either have to wrench harder or pound sand. If you really want a level playing field you should probably give up the 'hobby' parts of this and try racing video games.

What if your car gets stuck against a board and you goose the throttle in an attempt to free it. The current could spike enough to cause the "Cheater" LED to illuminate even thought the driver was in no way trying to cheat? Is that scenario possible with this system?

Until they find a way to restrict the driving ability of the person behind the wheel, there will be no way to have an even playing field. Maybe we should make the "fast" guys wear over-sized gloves or welding goggles to give the "slow" guys a better chance to win.

Maybe someone could build a specific class around this type of technology, but I'm not sure it is really needed at this time.

Another example of people trying to buy skill vs working for it.

I still love how people argue they don't have enough speed when if you sit down and actually watch close racing watch the top 10 guys. There is a huge difference of speed between them. The guys who win big races don't win on the straight away. They win in the corners cause they carry lots of corner speed to the point where their car is very hard to hang on to because it will rotate so fast. I have yet to see someone who runs a perfect 6 minutes and the ONLY time they lose ground is on the straight away.

I will never understand why some people are so obsessed with removing motor tuning from racing, but don't bat an eye at chassis tuning.

Well said.....people forget that not everyone can be a "winner."

I really am not too interested in this sort of device, but spare me the "bad racers are ruining racing for me" routine.

IF you want to go fast run mod. You can run any motor you want.
