I am currently building an on road carpet racer. Wondering if there is anything specific I should be looking for since I have just gotten back into RC and racing after a 16 year hiatus. I am looking for Servo, ESC, and reciever. I currently have a 27T Trinity Epic motor I will be using initially and rubber tires if that has any bearing on the decisions.

Actually I have figured out the ESC and am looking into the reciever and transmitter.. but what is a good servo?

I've the hobbico cs-140 to be a great servo for onroad, and it's only $35. I personally run it in all my onroad stuff.

Thanks will check it out..

You should be looking at a high speed digital servo. High speed allows crisp control through chicanes. Digital gives you more precise centering to prevent wandering in the straights.

I have to agree, if you can afford it then go with a digital servo. There are some pretty good ones out there for $50 to $60.

Troggie

Does it matter the type or Tx/Rx you use with a Digital servo to get the most out of it?

Druss

Not in most cases. You're not fast enough to see the difference. The only time I've seen a special servo is for helicopter gyros.

For Tx/Rx get something 2.4ghz. There have been a lot of posts about them so lots of information.

Just so you know the CS-140 servo I mentioned is a Digital servo, ball bearings and everything. Speed is good at .13 transit an it has 82oz of torque, which I've found to be more than enough for a car.

Yeah I am still sorting through all the 2.4ghz information.. though I may end up using an old Futaba 27Mhz AM that my dad still has from 16 years ago to start with so I can make sure I get the 2.4 controller I really want instead of just settling for one just to get one.

Yub, yub, cmdr!

The CS-140 which I ran on my Cyclone and then on my XXX-CR seems to have a -lot- of play. It's probably responsible for half the slop in my steering. I'm not sure if this is true for all brands' servos, but it's bothering me.
