I just got a new RS4-3 Evo and finally had the chance to start the breakin process. Before breakin, I swapped out for an Futaba FM reciever so that I can add it to the collection I have on one controller. I also swapped out the primer tank for a regular racing tank without the primer. After going over every screw making sure things are tight and secure as well as just checking things out since this is my first on road R/C, today I started it up.
Break in process was hell to begin with. I have never dealt with a rotary carb before. Starting it up for the first time was no problem. Getting it to stay running even at idle was hell. I do about 5 tanks with the car raised on a block which creates less stress on the clutch and engine during breakin since the wheels are raised off the ground and spinning freely. The factory needle settings just couldn't keep it running so I had to experiment a bit. I really don't like the way the rotary carb works especially how the idle screw makes adjustments. After about an hour of fiddling with the needles, I got it running fine to allow me to just proceed with a decent break in process. It's pretty much running very rich right now and I think I will continue to run it on the rich side with small lean adjustments per tank there after for performance. Other than that, it now cranks over real quick, spits some fuel out since it's rich for now and I am pretty happy with my first touring car even though it can't do what my Savage and Tmaxx can do.
 
Hey man congrats, I like the RS4 3 so much I have 3 of them. My first mods on the evo would be adjustable turnbuckels,tie rods and some new tires.You can really tweak alota performance outa these cars.
 
Enjoy you picked a nice starter car very strong & reliable :hammer:
Don't be surprised after the breakin process that car really moves :)
 
nice pick.the tires that come on the car are actually pretty good they have good traction.
 
Good choice. Won't be dissapointed with it. MAybe next race season u can join us.
 
ever heared of heat cycle break in????
do it.
running to rich aint good. and letting it idle for few tanks is very bad also
 
I never said I ran it on idle for a few tanks. I said I run it on a block for a few tanks to create less stress on clutch and engine since it's raised off the ground. For the first tank, is the only tank I let it run on idle and even so, my first tank didn'trun on idle for long since I had trouble keeping the truck running for the first tank.
As for running it rich, I said I plan on leaning it out each tank there after. I use 20% nitro and running it break in rich is like using 10% nitro, less nitro with more oil content.
And yes, I have heard of heat cycle break in, butI have also had bad luck following other peoples advice for break in procedures and so far my break in style has worked great for me for three different engines on three different rides.
 
Always go with your best procedure & just make sure it is not running very hot.
 
I just painted a new body for it just to show it off at the HPI Challenge this weekend.
