I think this was discussed before.

 

Unless I'm missing something, it looks like you have to take the axle in and out, each time you true the tire.

Did a search and found nothing.

 

In all the races I've been to I have not seen a single one. Nor have I seen one in any of the hundreds of pics of racer's pit tables at races all over the world. Is this a recent entry into slots?

I definitely saw one and commented on it... somewhere... a few years ago.
 
I'm guessing the maker thought he came up with a superior axle support system, but until we start running cars with the bearings on the outside of the chassis, it's not really going to accomplish much.

Cheaper here. I like the Backtrack design better though.

PN historically was a company making parts and accessories for Kyosho Mini-Z. I sold a ton of their stuff in the early 2000s. Absolute top quality but this looks like a "repurposed" item from those days.

Just got it.

Quality is good and well made. The drive pulleys are a bit delicate.

I cut a tire and it is straight, but a little rough. The standard grinding wheel is on the rough side. I also got the fine wheel, so I will try that. It has a micrometer adjust screw stop that is nice.

One observation I have on the Hudys is they tend to be a little low on power. How about these?

At 3 volts the motor pulls more amps than a Hudy motor.

The truing shaft is a little bit of a hassle; it has threads on the end so it screws into the pulley wheel.

Does the shaft have any noticeable run-out?

How much effort does it take to screw it in and out?
 

Drive belts could be replaced by Ace Hardware O-rings.


While correct, isn't that the case with all tire truers?
 
Or are there some I'm not aware of that are chain drive? :laugh2: :laugh2:

There's about 3/16" of thread. There was a burr where the threads meets the smooth portion of the shalf. Had problems with inserting the tire until I polished it. The procedure is like fitting a crown gear to a car.

The truing shaft has a flat across the whole length. Don't know if theres any runout. I cut a tire and it was straight and flat, and I spun the cut tire on an axle and didn't see any wobble.

What is the largest diameter donut you can fit onto the truer on a 3/32" axle?
