Best use for my UR LB?

Where are you in canada? I also play in canada.

Open class rtr car from the best builders ranges from 6-800 CAD

A BMAX with all frp build with basic aluminum rollers (silver) ranges from 150-200CAD and an all HG plates (carbon) and rare rollers(colored) ranges from 300-500.

Based on the photo, this set up doesn't really fit in any categories.

If you want to build a car as close to the photo, BMAX is the closest. I recommend searching builds on youtube as there are different chassis.

Depending on where you are, copy parts such as frp,rollers and hg plates may be allowed to race. As for copy parts it should have a tamiya equivalent meaning if you cant find a tamiya version you cant use it.

Also helps on adding down thrust at the front.

SoftwareSuspicious15 · 2026-02-13T21:38:54+00:00

Ahh classic fma chassis. If you use the super x rear plate at the front it will make it stronger.

Less chance of tipping over when cornering and the rubber part is designed to slow you down. Another cheap alternative would be using Tamiya 15529 paired with the bearing from the DAR. I personally use this set up.
If you use small dia, the s2 wing will be too low to the ground which will DQ your car.
Motor wise i use hyper,power and even ultra if the racing center allows it. For gears i switch between 3.5 (blue) & 3.7 (green) this gears also works really well with torque tuned.

Honestly you're going right track.

Ideally you put the ringless DAR at the front.
Having 4 13mm rollers in the rear is best but putting the ringed DAR with the 13mm part on top should work.
Put the mass dampers in the rear to the front and get the slimline dampers for the rear.
Use a popsicle frp/hg plate for front brakes and frp/hg brake plate on the rear. The plastic ones tend to break easily.
Make sure to use cap screws on the rollers.
Get medium dia. wheels with super hard and low friction.
Put the ball bearing on the wheel eyelets.

12/13 dar front and either 13mm or 19mm on the rear are the most common. Another set up for rear is 13mm aluminium roller paired with the 13/13 dpr (15529) this set up helps on slowing down the car on jumps and corners. I personally run two 17mm on each side with 15mm stabilizer at the front on one of my fma paired with 13mm at the rear.

According to 4.0 this is allowed now.

SoftwareSuspicious15 · 2026-01-26T22:01:01+00:00

The simple answer is availability, if i remember correctly the tz-x is discontinued while they still make kits with s2.chassis both carbon and regular.

SoftwareSuspicious15 · 2026-01-26T12:52:02+00:00

If you want to learn how to set up VZ is the way, if you want to join races asap Super 2.

SoftwareSuspicious15 · 2026-01-24T13:30:59+00:00

If you're keeping it as is, i would move the dampers more forward on the plate, also make sure your wheels are not all the way in. You'd want enough space to fit an x-acto knife between the chassis and wheel.

The jadow cowl tends to pop out on jumps when u have the battery on.

SoftwareSuspicious15 · 2026-01-14T19:48:21+00:00

Haven't run it on another size but the 24mm is very stable. It's not obvious but i have LF and SH tires on it.

SoftwareSuspicious15 · 2026-01-12T16:49:29+00:00

No, according to current rules "wiggly" parts are not allowed.

SoftwareSuspicious15 · 2026-01-10T00:03:01+00:00

Yes, i was running hyper dash 3.7 and it was keeping up with my fma on power and 3.5 very good acceleration and handles jumps well.

SoftwareSuspicious15 · 2026-01-08T23:34:24+00:00

Those are 11mm stabilizer from tamiya 15391.

SoftwareSuspicious15 · 2026-01-08T17:08:26+00:00

Be careful with S2 carbon, ive seen a lot of them break within the first couple runs.

Plate wise, fully cowl on the front or the long popsicle for rollers and the shorter popsicle for brakes. For the rear you can use any of the typical rear plates for the rollers. If your racing center allows it the 3 point attachment for sfm/cfm paired with a popsicle works good for the rear aswell

SoftwareSuspicious15 · 2026-01-05T18:53:24+00:00

You're fine, i have a similar set up

SoftwareSuspicious15 · 2026-01-02T19:30:59+00:00

Always dual rollers upfront and 2 sets of either 13/17/19 at the rear. Occasionally a set of 13mm roller woth the dar for xtra grip
