Anybody here CS a Losi JRXS Type R?

Postby ToraKitsune » Fri Apr 26, 2013 10:48 pm

Hello!

I have, as my second upper-level drifter (presently 50/50), the now-discontinued JRXS Type R.

My problems are: The chassis is not metric, but SAE ( I do have a collection of spare fasteners and parts for it), and Losi Parts House doesn't stock pulleys nor belts of the right size, and I would like to know if anyone has CS'ed one of these chassis, and with what parts? I really would like to CS this chassis, as it has been a solid performer in 50/50 mode, and should be tricked to do CS. It has only one layshaft, and I believe I can still get them, so if there is a mod that works, Please let me know! :)

Thanks in advance!

Hi , unfortunately it is not JRX-S , the first mid engine with a distribution of 50/50 weight :P

You can get the pulleys from a xx-4, the old school tt chassis, 27 teeth is the perfect fit for the rear diff.

Will give you overdrive and you should get an motor 13.5 above .

Surely you use the CVD's with more angle and also the 8 degree c-hubs or not?

You'll have to do some belt tensioners for the belt or buy a new one , more help just with your chassis in my workbench ;)

good luck :up:

O.K., thanks for the reply and info! :D I go to LPH all the time, and just never knew which model to look up, to get CS-compatible parts. So, with those pulleys, what ratio do I get, and why the 8 degree C-hubs and knuckles? I have found the stock angle (2 degree) to be close to perfect, by keeping the contact patch up front even, across the entire steering radius, but if I'm wrong, please advise, so I know why. And yes, the JRXS-R came with the front LCD's as standard equipment. :D

More caster will give you more "grip" in full lock , even with 0 camber you will get 6/8 degrees at full lock easily . and the look is more realistic.

Without changing the center pulleys you stay with 155% , just use de 27 teeth in the rear , not bad :up:

Oh...O.K., I thought having less caster would leave the tire contact patch at near-full, even at full lock, with 3 degrees or more camber. I'll give the 8 degree blocks a try!
Are you sure (my math could be faulty), but I put my numbers into the CS calculator, and came up with 116% which I thought was awful low. I'll be making another order with LPH soon, so will get all the parts you guys recommend! :D

Nop ... 42/23 - 23/27 gives you 1,56 % ;)

I have some Q's.......After a cursory look at the rear end, It's pretty tight in there.....The 27T pulley, is it small enough that the belt will need to be re-routed above the motor shaft? There's some lee-way with the diff concentric, but I'm having trouble on where to locate the tensioner. *-| I don't know if LPH sells a shorter belt than that (I am placing an order with them either today or tomorrow), and help is much appreciated! :D :up:

Yes , I said you had to improvise a tensor ...

See the example of the Yokomo drb , perfect engineering :lol: :lol: :lol:

Yah, I got you about the tensioner, I asked where I could put it. I think I have an answer, but I will have to have the pulley installed first to see if I'm right about it. The shorter belts in the link are metric, not SAE, which is what the JRXS-R's belts are, A small difference, but enough to matter. I'll work it out, just have to get the pulleys first! :P
