Gyro's banned

I see on Redrc efra have banned the use of gyros, I know in 10th they were banned many years ago after the LRP traction control system etc

Just wondered what they would actually do to the handling of the car with one fitted?

Would it really make that much difference? ie would a top level driver be able to shave off a few tenths a lap with a gyro fitted?

I reckon, for a world class driver it would make them slower, but for your average Joe, they would be more consistent than without, as you will be telling the car how much steering/power and the gyro will actually be controlling the servo's for steering and throttle.

The gyro autocorrects the steering when the rear of the car tries to slide out, keeping it pointing where you want.

On a very slippy track there would most likely be an advantage to be had, if set up correctly.

They mostly help drift cars from spinning around, cant see it helping in most scenarios.

briefly tried one on a low grip track and I was a fair bit slower and more prone to crashing. The car was constantly fighting what I knew was best.

i don't know understand why kebabs are being banned?

[neallewis]

from my experience flying quads which use gyro's to keep the things in the air, there is an element of gain tuning that needs to be done to get the best input and feedback tuned to where it needs to be. never used one in cars, and won't, but i think the neobuggy example video had the gains turned up somewhat to show an extreme effect.


I think bashers, who can't drive in a straight line, will be queueing up to buy them, unfortunately.

and then find it extremely difficult to adapt if they move onto racing.

This is just my opinion and mine only i am sorry to say but any gyro fitted to any rc car is a form of cheating and if you cannot drive a car without having one of these fitted why bother going out in the first place


R/C is supposed to be about fair and share if people are using gyros then this is not a very fair way of playing the game or being a good sportsmanship;

I am not saying do not use these on test days but should not be used at any form of meeting whether club regional or national level ;

Like i said this is just my opinion and no one elses

To answer the question of the topic starter:

yes it makes a big difference in handling.
There was a time when gyros were allowed, and you could just pull the throttle whatever grip was there you wouldn`t spin.
The cars were setup with tons of steering and the most forward traction you could get.
Driving was point and shoot, you just brake the car around the corner and then hit the gas.

My gyro once failed in a final an I tried to go without. The result was undrivable- just like using yellow Schumacher tires on clay when everybody else is running Holeshot .

In the end the usual suspects were the fastest.

gyro's will make a poorly setup car handle better, but wont help much with a well set up car, or help any driver that likes to be able to throw the car at the corner. very useful if you want something like a speed run car to be more stable, not tried but i cant imagine one helping much off road. they do help quite a bit in a heli but setting up is a pain in the ass

I know some of the Drift 2wd drift guys use them.
There was a chap at our track last summer testing his 2wd drift car with a gyro as it was uncontrollable without it

[SlowOne]

I don't understand why they needed to issue this. Rule 4.2 in Appendix 3, Electric Cars clearly states:

"Automated steering, gyroscopes to control car movement, traction control, active suspension are not allowed."

It's the same in the IFMAR Rules. I wrote them almost 20 years ago! Why did EFRA not simply quote the existing rule?

Checking is easy. With the cars on the line ready to start, pick one up and waggle it from side to side. If the front wheels steer, take the car away and ban the driver!

[KRob]

Slow One, the press release from EFRA/IFMAR is none class specific but it has been put out there because of the 'rumours' that '8 of the top 10' at the recent 1/8th RallyX Euros B were using gyros.

[neallewis]

Cheaters. like some others using tyre additive at the 1/10th Euros warm up the other week.

[bomber]

Spektrum have their AVC system that is a gyro and traction control all built into the receiver, having drove a 1/8 buggy with this installed I can only say the advantage would be massive if used to race, it is definately cheating and needs to be scrutineered for somehow

According to the blurb , the avc receiver comes with a blinky mode to show that avc is dis-abled , so should be easy to check !

Thanks, KRob.

Checking is easy. With the car ready to race and the Tx out of the driver's hands, pick it up and wiggle it from side to side. When you do that the front wheels will steer - gyro fitted and enabled!!

I imagine that it could also be attached to the throttle to trim the car in flight, so tilting the car up and down should make the throttle servo move as well.

Whether gyros are fitted or not, the qualifying order will be unchanged. However, we will quickly get back to the programming with a lap top that we had with BL speedos before so many classes went 'blinky'. Good to see EFRA sorting it out quickly before software wins over driver skill.

Does it have an altimeter then so it knows its pitching in the air and not say going up a ramp of a jump?

[MHeadling]

A good video demonstrating gyro/AVC

most gyros are single axis and only control one channel (on heli's its the rudder channel) try flying a heli without a gyro is a mega task

there are dual axis gyro's which in theory could be linked to both throttle and steering channels on a car , it wouldnt be an altimeter control but i can see where Mark is coming from , on an upslope the pitch angle may induce the gyro to act and open or close the throttle (on electric im not sure this would be possible but on a on a gas car with throttle servo i dont see why not

heli pilots better than me please put me straight if im talking codswallop
