electric touring car servo?

[spongebobspongebob]

I'm building a TC4 for carpet racing. I've got my electrics mostly picked out, but I am having a hard time figuring out what steering servo to go with. The guys at the track told me that speed is the priority then worry about torque. I buy most of my stuff from tower, if someone has any suggestions, it would be appreciated.

Futaba 9405 Is What You Will Need For That Car Don't Get To Crazy This Is The Perfect Servo & Is What Majority Racers Use In These Parts Of The Woods. Average Cost $80

MOST IMPORTANT IS SPARE PARTS ALSO DON'T GET CAUGHT LIKE I DID WHEN A NEW CAR IS RELEASED THEN YOU BROKE A PART & NO ONE HAD ANY PARTS THAT I HAD TO ORDER IT FOR OVERSEAS

thanks for the advice

btw, I had thought about parts availability, but I hate to buy a tc3 when the tc4 is already out, and I'm sure tower will stock all the parts shortly. I buy from them almost exclusively because there are two hobby shops here, and only one of them stocks car parts at all, and it's a super small shop. Tower has a tremendously better selection, about 50% cheaper, and I usually recieve my shipments 2-3 days after I order. I wish we had a good hobby shop here.

Then head to the little shop and buy your stuff. Help them turn it into the good hobby shop you are looking for.

i run futaba digital servo 9350 in my tc3 i love the speed of it

look into the futaba s9451 digital servo. it's the same price as the s9405 ($80) and it is a much faster steering servo. being a digital servo, the movement will be much smoother than coreless or regular servos.

As it was explained to me by a seasoned veteran of competative electric racing, speed in the steering servo is very important. Turns are tighter, traction is higher and motor response is faster than nitro. All this requires almost instant response. Also important is that you set your steering according to the track layout so that when you steer, you're at full sweep. Throttle control is what will determine over or understeer.

The driving dynamics are much different than nitro since there are more axis of rotation giving nitro engine's a disadvantage of steering response and handling characteristics. Electric's have less torque steer because it has a linear plane of rotation Electrics with shaft drives will tend to have slightly more torque steer. As a beginner, there will be little noticable difference.

Yeah it is always good to support your local hobby shop & when you become a good customer you may just get the discounts that save you more than buying online. You can't put a price on service with a live person over the internet.

Regarding not knowing the difference if you go with a high torque servo with very minimal speed versus a good speed servo you will definately feel the difference on return speed demand will cause you to not keeping the on power demand with steering response. Don't get to crazy with all the suggestions. you may want to ask what's the favorite servo that is used in the track you are deciding to go to. you don't want to much over speed servo it will make the car very hard to drive until you get used to it. 9350 has less speed than the 9405 as for sloegin suggestion that might be to much speed that servo is perfect for a 1/8th but might be to much for a touring car the 9350 is also a low profile servo which is what is recommened for the trinity G4 nitro since the bulk heads hits the standard size servo.

I was referring to the torque steer dynamics of a shaft vs belt driven car, not the servo.

OPPSS my bad

I've been looking into all these top shelf parts for the car I'm building. Last night I went to the track for practice night, and got to drive a xxxs. This car was set up for spec class with a cheap servo, and it was way faster than what I can drive. I think I'm going to focus on getting a race car together so I can race and practice this season, and not so much on having a top of the line car.

If this was the first time you will see a huge difference with the car outdoors then indoors., indoors you will have tremendous traction&speed versus outdoors with shock positions needing to be changed outwards. what motor were you using & spur,pinion ratio

 

[spongebobspongebob]

the motor was a trinity street spec. I don't know what gear ratio it was using. They combined spec and stock class. You can either run a stock motor with a 3300 battery, or a spec motor and a spec battery. I'm sure that outdoors, I wouldn't have thought the car was so fast, but on carpet, it was plenty for me, at least until my skills improve.

 

[710baby]

Check the ratio here is a well used setup for a stock motor 128 Kevlar spur/30-35 pinion or you can try a 98 spur 36-38 pinion then you will see the car perform like it had a 19turn motor in it
