<----- It's hard to drive a car setup with these nanny controls as I call them, after driving no expo for so long. If anything, no expo is like having negative expo.... because the steering is not linear and falls off as the servo horn angle increases. Expo compensates for this. I agree that expo probably has more potential though.

I put black grease on, and tightened it as much as I could without it locking. It had no grip probably because of the grease. Oh well. Would be cool to have more adjustment there instead of all or nothing.

So just finally got to spend two days at my local track and worked a few things out. Ok conditions were mostly light water to med dry clay indoor with plenty of bite in the groove. Set up was tekin 5.5 550 short course motor and rx8 speedo. With spectrum started at 14 61 kinda to slow and too much torque. Moved to the 58 bingo more top end maybe even 57 or 15. Some timing advance. Slighty tweaked exPo -5 and 15 throttle punch. No sway bars stock oil and out side bottoms middle tops. Stock diff fluid no sway bars. Felt good I'm new to 4x but am top 5 in stock short course. Got about 1 sec to 1.5 faster and felt better by days end This truck rocks nothing broke and fells amazing. Btw clicker was loose sounding like a fishing rod I love two wheel feel Gonna stick the oils in diff and shocks and up grade the slipper pads and it's race time Awesome days trucks badass

TEKIN RX8

Do 550's need 8th scale sized speedo's?

Can an SXX TC/RS Pro/Havoc Pro etc run 550's without issues?

I still dont know if I should run big motor or little motor.

DOES NOT NEED BUT HELPS WITH TEMPS.

I run a 4.5 550 with a novak kinetic with no problem. Esc temp is between 90-100 running the fan it came with.

To make the links you will need,
2x #89092
1x #4671
1x #89091
2x #31286
2x #5190

as well as RC8 shock end pivot balls.


Take the sway bar eyelet and cut 2mm off of bottom. So this for all 8 eyelets and then screw 2 together until you see 1 thread showing between them.

Next install the shock end pivot balls on one end of each link and the sway bar joint on the other end of each.

When installing the link into the arm, put a 1mm shim, #31286, on each side if the link.

Now mount the bar to the chassis, you will need TC5 mounts #31264, and 2.5m x 8 screws #89222

You will need to bend your own bars.
I recommend getting some 1.5 2.0 and 2.2mm wire. If your hobby shop only sells SAE sizes its .059, .078, .086 wire.

i run Havoc Pro SC + 4.5t 550 + 12t pinion + 25deg of timing

i temp 90f on esc 125f on motor

its fast as hell, faster than what i can handle, lol

Thanks for posting. Looked up all those parts. Over $50. And I think the #5190 may be wrong. At least I cant find that part number. That or the RC8 shock end pivot balls.

Honestly thought I dont know if a sway bar would do me any good. I think the truck handles great. I havent traction rolled even once.

i know a guy runnin the Tekin 4x4 6.5 with regular Tekin RS at the track. works good. i plan on pickin up the same motor soon my self.

maybe ur not tryin hard enough? lol, j/k. i run in hardpack clay that is super high traction and coming into the sweeper fast(30+mph) and u easily traction roll, i have to let off and/or brake for a sec then get on the throttle again so it doesnt go into a barrel roll.

driving the truck today with the clicker locked down for the full four wheel drive affect..went to try and loosening it up for more 2wd affect and no go.. i backed out the nut practically all the way with no thread showing and still didnt do anything!!! has anyone had this issue???????

Why? I would think positive expo is positive expo, regardless of the servo manufacturer?

That is just the way that radio manufacturer labels it in the menus, a positive number in spektum-Jr equals negative expo to the servo... Kinda dumb, but no biggie once ya know it...
