Default touring car advice

Hi everyone,

I'm looking to get a 1/10 TC to race indoors for a few months this spring and I need a little advice..

They only run a mod class at my local track so I'm not expecting to win any medals just don't want to be holding anybody up

Most of the guys are running Sprint 2 with brushless. I'm not sold on belt-drive and right now the TC4 is looking real good - lots of parts available through my LHS and a couple of friends running them so tech advice is available...

The Sprint 2 Flux is good value but I'm a little hesitant to go brushless right away.

I have a Novak GT7 that's not being used so I was thinking I could save a few bucks and get either a TC4 or Sprint 2 Sport with a good modified brushed motor for this season while I learn the ropes.

Being a newbie I have no idea what kind of motor to look for (ie. how many turns) or if this is even a good idea

Any thoughts?

I hope you have drive an r/c car before to even think about running mod. But if you feel you can run it I'll start with a trinity base 10t cobalt motor it should be able to hang with some mild brushless mod motors. Good luck!

hehe, Thanks for the advice and I hear that.. Saw a couple of guys at the track that had way too much car for their skill level - And I don't want to be one of them Do have some RC experience, currently have an RC18R, a slash and an old Tamiya MT. Running the 18R on the same track starting this weekend so I think I'll be good.

The GT7 has a lot of adjustments too that might help smooth out some of that power..

A 10t brushed motor would be pretty quick, I wouldnt see any problems using that in the mod class.

There are two types imo.

The more expensive ones will be fully rebuildable and the armature is likely to be hand wound. Brushes will be 99% of the time, soldered onto the endbell.

The cheaper ones will be 99% machine wound armatures, and might have eyelets on the brushes.

Maybe even a 19t checkpoint motor would be ok, with hard brushes if you can find one...

i myself feels that a faster motor is easier to drive like a 5,5 then a 13,5 motor. sure,its faster but i feel i have better conrol over the throttle.

becuse when you are running a slower motor you have much full trhottle in corners. and that takes away the feeling. thats what i think. but if you are a beginner. i would start using a modified motor thats fast and then turn it down on the radio until you think you can control the car and track good.

Do you have a com lathe?

If not forget brushed as after a few heats the motor will be gutless - dead etc
I need too cut the com an brushes after two runs or so too keep it competative
and the price of a decent brushed motor isn't exactly that cheap either
hav u thougt about say a hobby wing brushless combo? There pretty cheap an would last you long enuff till ya figure out what it is your after

or you can pick up a good second hand brushless combo from here

Does it really wear that quickly? wow.

I'm not opposed to going brushless. Just worried that it'll be too much power.

What would be a good entry-level brushless system? By that I mean not too powerful.

Thanks again!!

Belt drive is definitly the way to go. I have had my tc5 for over a year and run it every week and my belt has never broken or had anything go wrong. A TC5R is the best setup since ur running mod.

It all comes down too ya driving skills and the size of the track you are running on

too begin with I'd suggest something along the lines of say a hobby wing 6.5-7.5 (maybe even 8.5) for mod then see how you go and worry about upgrading later if you get better hobby wing speedy then all ya need do later is upgrade the motor
or jus upgrade the whole lot as you improve
the hobby wing is a pretty cheap yet reliable set up that should give u enuff grunt etc too get yaself into trouble lol

as for ya car choice I'd go for a belt drive car over the shaft drive - I hear torque steer is an issue with shaft not mention the belt drive seems a bit more efficient and not overly dear for good second hand unit with spares
