I didn't know. You would think JC would have it on their site. Thanks.

For those of you have done the hex conversion, do you notice you gain a lot of slop?

I have check out a few people who have done the hex setup, it seems there is a TON of play between the hex and the pins, added to the play it already has, it seemed like the cons out weight the benifit. Maybe its just me...

are you talking front or rear,i don't have any in mine

I don't have any slop.
When you add the shims you still keep those two little shims between the bearing and pin on the axle.

Mine are running strong. haven't even broke a axle pin for a while lol

I have not done the conversion but will be buying parts for it tonight provided my lhs has everything in stock. My question is... my front end on my FT seems to have some normal slop in it and thats what I am wondering. Is it normal to have some wiggle in the steering itself?

Also I have been looking into replacing my servo with something upgraded. Sugestions?

seems some reviews on the jconcepts hexes aren't very good.

what about the ST Racing concepts hexes?

you guys think i should scratch the 75 and just get maybe the 84 and 81? from what i read most running 13.5 blinky are using a 84 spur..

'Not an expert'
I run 13.5 - 23/75 with only 6deg physical timing and it never goes over 150 even after 20min of running. Any higher on the spur and my speed would be like that of the 17.5s at my track it seems to me.

so you would lose some bottom end in trade for top end up you ran a larger spur?

I haven't noticed anything like that. Assuming the ratio comes out the same, the performance I have seen has been the same. the main thing I have seen is the position of the motor affecting how it handles.

i just want to get the right spur without ordering a bunch of them lol.

no prob I fully understand that LOL.

heck, I was thinking of going with the inbetween spur myself, the 81T.

im thinking so. i may just wait. i forgot they are fully stocked at the track. probly just ask someone there. :nod:

Larger spur would make it gain bottom end/lose top end which doesn't seem ideal as 23/75 has what seems to be the same top end as the geared crazy 17.5 blinkys at my track.

In researching 13.5 no boost gearings in the past I came across: 25/75 & 19/81 for OCRC or something in Cali. Idk...
