diff
Paul, I rebuilt my diff and I installed Xray ceramic diff balls along with a Xray ceramic thrust bearing. Now the diff loosens each time I run. I've double checked everything and all is installed like the book says. Am I missing something or why is it doing this?
Also on another note my car is somewhat fast, but it's hard to drive. I would like to take some roll out of the car. When going threw a chicane I want the back end to be more planted. It seems I have to chase it threw the chicane.
Thanks,
JG

Hi Paul,
Hoping you can help me out a bit with this, I am totally new to 12th but looking to run one soon, with a 17.5 TP motor and lrp sxx tc v1. From the above, do I need to remove any esc wires to the rx or do I plug everything in just as I would a 2s car, but then also run an rx pack, and with the esc switched off? Will this work?
Also, will I be ok with a standard TP 17.5 motor for 1S racing, or does it really need option bits to run?
Thanks,
Dave

Thanks!

It's more that I end up widening the slots and holes in the axle, dog bone and ECS 'casing' where the pins go.
So I end up with lots of slack in the drivetrain. The main problem with that is that we can't buy the axles separately.
Haven't snapped a pin in a very long time.
Occasionally I also bend a dogbone (managed it last Sunday).
This sort of stuff only seems to happen to me when carpet racing due to the close and less forgiving barriers.

the bone is also sold serpately but no i dont see the axle sold seprately.
sorry i couldnt be more help.

I suppose that it is also possible that that plastic pece is their but is worn out and not holding the threads of the screw, then i would try to replace it.
The only other thing that it could be is that the thrust is not working properly. if their is some extra drag in the thrust side with the diff screw, thrust washers, and or outdrive it could loosen up do to the thrust not doing its job properly.
You will have to trouble shoot it but those are the only scinarios that i can think of.
Thanks, hope you figure it out. if not PM me and we will take the next step.

hi paul
do you run drag brake on esc what percent do you normally run and if you do, do you change through diffrent tracks small large etc.
thanks

Hi Jake, I do run drag brake. it is defferent on different speedos though.
On my LRP i normally start at 3 and sometimes go to 4 if i feel that i need it.
On carpet i dont find it as nessissary bc you can kinda throw the car in to the corner and get it to slow down like that but i still run 3 or 4 normally.
On asphalt it is very important to have a proper amount BC you need to be so smooth and really slow the car down before laying in to the wheel getting in to a corner, all to not overheat the front tires.
really those drag brake settings still mean nothing BC Drag brake is highly dependent on your gear ratio and rotor as well. But yes drag brake is good, too much is not good though.
Thanks

Hey its alex,
I just wanted to say thanks again for helping me with Lipos, and I'll let you know when I have some time during winter break so I can come testing with you or whatever. Your the man Paul! Best in the midwest and nation ! Do you have any off-road stuff? Would love to race against you haha , if you race with people who are better than you, you are going to want to push yourself to be better!

hi paul
with 17.5t boosted how much motor time should i run
ran motor for the first time last night and it felt real good on 6.35 motor temp was 89f but i turned motor timing up to 35 and motor temp went up to 189f so dont know whether to go to 6.2 as you said to run as i run hw xtreme stock track in 1 more carpet wider that iic but same length

Paul..
to add on to my question with the rec pack with the lrp... why did u choose the ss v1 over the v2.. and will the v2 be ok to run arec pack?

No problem. i dont have any off road stuff right now. you dont want to race me in off road anyways, I suck lol.
see ya.

Hi. it all really depends on the speedo setting. the motor will run its coolest at 15-20 deg timing, for 17.5 boosted i would run it at 20deg, 6.2 then tune the speedo to have the motor run 180-190 deg after a whole race. I think then you will be close. for your motor to jump up 100degs seems almost impossible. i would go back and test that again. when temping the motor find the hottest spot and always measure it from that exact spot. make sure to ease up on it with the speedo setting.
no problem!
I hate to pawn your question off, but you may be better asking one of the AE guys on here BC i am more than a little behind on the LRP testing right now.
Sorry, Thanks!!
sorry.
#1286
Paul, do you ever tune with stiffer or softer chassis/top decks? If so on what conditions do you make a change? thanks
#1288
For your refrence I felt like on the T3 2010 car the right amount of flex was the stock chassis and top deck with the steering stand offs and all the availible screws. Thanks!!
Good luck

hey paul. awesome thread mate!
would you know what kind of mechanical timing on the tp 17.5 z3r would be optimal for 12th scale 17.5 blinky. i have a blue rotor but no stock rotor. thank you in advanced!

In timing speedo classes i would prefer to keep the motor in its best range of efficiency (10-20deg for TP motors) to keep the temp down, Then Time the speedo.
Thanks.
