What are you guys seeing when you advance the timing all the way?Better to leave it or better to move it forward or back?

Jake

On the 4300 it doesn't do much. Really no point to adjusting it at all. Never ran the 13.5, but I'll bet it has a similar reaction.

I race the 13.5 and have not changed timing. Nor has anyone I race with. As LARCGuy said, "Really no point to adjusting it at all".

I say just leave it alone
Don't go try and mess with a good thing If ppl start doing this and trying other things than we will just have another can of worms like the 4300 class different rotors endbell timing bearings
We are running the 13.5 just the way it comes from novak and thats the rules in atleast 3 tracks I know of and I think the BRL is the same Not sure on that one though

hey man how's it going ?
i'm fine except for these scars i have on my knee and elbow.......lol


13.5 motor
i ran my motor straight out of the box and it sucked.
i had to turn up my timing up on it because it would not take off very good.

I ran it that way at the brl race in michigan and it took about a lap to get up to speed.
I put in a reciever pack and still no help.

so i turned up the timing and it fixed the problem ........

so a little advice is to turn the timing all the way down and it will run it's fastest..................... lol he he he he h e

later

Mine came with the timing turned all the way up out of the box.

My results have been turned up the timing all the way no diffrence then how it came.

Some say it helps, but like all motors some are good and some are not so good.

There is nothing in the BRL rules that say anything about timing on a 13.5.

Some thing intresting all so, in our club races have rolled out at 2.35 all the way to 2.60 with out much change.

Some are running at 2.55 and say they cant stray from that number mine SUCKS at that number.

Mabey it time for a diffrent one? :rolleyes:

Jake

On the 4300 how do you tell where the timing is and how do you adjust it just curious??

On the back of the motor there is 3 screws loosen them and turn the black plastic ring after the sodering tab rite befor the can.Looking at the back of the motor move the ring counter clock wise to advance.

I have not done my 4300 car yet because it works fine so far but do have the rotor and front bearing cap up grade for it. :thumbsup:

Jake

JDW- You said you have an upgrade kit for your 4300. Have you tried using another replacement rotor or the upgrade kit in your 13.5? I've noticed that if you've thermaled the motor one too many times,the magnet in the rotor weakens. My 4300 motor was going south after numerous thermals. (maybe some of the rotors that originally come w/the motors aren't the best in the world?) After installing a direct replacement rotor,it woke the motor up!

As Promatchracer said,don't mess w/the timing.

I was trying to keep to the BRL rules for our club races so i did not want to put a sintered rotor in the 13.5 but a new rotor would be a good idea.

Or how about shimming the rotor in the 13.5?Where to shim and how much?Isent the rotor placement in the can important?

The guys I race with would not care but we like to keep things fair.

My 4300 is stock no upgrade or anything(i have the upgrade waiting when it goes south) and works really well at this time.I have been running it hot though about 172 deg :cool: with a LRP sphere.

Jake

Thanks for the timing info Jake.
Andy

I set my timing back to half way made no diffrence I could tell anyway.So I took it apart and oiled the bearings turned the timing as far forward as I could and put 2 shims on the front shaft took some slack out of it.allso running it with a GTB.

So back to the drawing board this week.

172 is kinda hot dont you think? Your rotor must have no magnetic power left. I have heard of guys zapping the rotor. With success. When my motor got that hot i replaced the rotor. Kinda like brushed motors you get them hot and the mags lose power. Sintered rotor= 2 more teeth. As for shimming just take out any slop. Most of my motors dont need any shims. they are tight. As for rotor placement, you shouldnt have any problem.

I ran the original rotor for an entire winter and then summer outdoors, getting it quite hot. I then compared the field strength in a helmholtz coil to a new rotor (run once to stabilize it). If I remember right the field loss was less than 1 percent, which is less than the tolerance on the field strength in the first place. To be fair I never thermalled with that rotor though, but did get it quite hot.

I then proceeded to knock down the field with a coil type magnetizer. Using that magnetizer I wasn't able to fully saturate the magnet again after knocking it down. Without a fairly large capacitive discharge magnetizer and special fixturing guys aren't going to be able to do much for the rotor by zapping. Before anyone asks, again that was the original rotor.

The one thing here i have noticed from talking to people.. whenever the cars slow down,people instantly seem to think there is something wrong with these motors, or they lose performance.. Then they finnally get there car setup better and boom the performance is back.. With these things setup is so much more critical.. I have had two races in a row, where i was 1-2 laps off the pace in the first two rounds.... My first instinct was to think man my car feels so good, these guys must have a secret to there motors.. On both days at two diff tracks, by the third round my car got better and better.. I ended up TQing both races, and ended up right next to the times of the guys who i had thought new some trick..

Our track record holder in 19 turn, said he had a motor he ran last year.. said he thought it was junk.. he had to use it the one day for some reason.. he not only re broke record, but he realized it all in the cars..

Burbs you are on to something on my 13.5 car i have changed the set up quite abit every week trying to get some laps.Car ran the best the first 2 weeks I ran it with the 13.5 then the weather got alot colder and had to switch foams to get traction and the anchor began to drag.I am running a KSG Gen 2 and it has a ton of set ups to go through.

But I can say I race with a guy with the same car same GTB same 13.5 same foams same springs side and center even ran the same spur and roll out he did and car did not run the same lap times could be the driver but even a not as good driver will have a few good laps to show what the car can do.

Now on my 4300 car yea 172 is too hot. Last week it was around 155 I want to go down a few teeth but the car is so close to the others I hate to F with it.Car with the slowest fast lap won the main.

But I did change both Gen 2s to a diffent t plate so who knows this week.

Jake

We havent raced 13.5 in a few weeks been racing the 4300.

I did run it for a few laps this week and though not up to where I wanted it was better with the timing all the way forward and roll out at 255.

I think when I moved the timing befor it was not all the way advanced this time I took it apart and cleaned oiled and turned it at the same time

It had that high wine sound this time out.

Jake

Its the set up blown shock bent axles ect.Lesson check you car alot
