When I looked at getting the new kit at Xmas time I priced up the upgrades from S1 to R1. The new kit is alot cheaper. Didn't look at the S1 to pro. I will be getting a pro at some point but I want to get a guitar first (Epiphone Les Paul, either LP-100, Traditional or Standard) I am just learning to play but want one that will inspire me to pick it up every day.

Does anyone know if the body posts for the Pro Spec are in the same position as the S1?

car geometry should be identical minus the top deck and motor mounts from S1 to R1/Pro Spec

My bodies transfer right over.

Almost all parts are transferable. I think there are some different length drive shafts between the two, but that's it.

Hi all,

What the benefit of the white POM bushing on the spur gear holder compared to the kit black plastic one?

Cheers

Well... my spurs are somewhat thinner than others. So after you screw the two belt pulleys to either side, the whole assembly is more narrow than say using a Spec-R spur.

So by using the longer white bushings, it eliminates any side to side slop in the center pulley. Easier than trying to fit spacers in there.



The stock photo from Spec-R shows them using the white ones with the R1 because the aluminum is likely thinner than the plastic. But they work well for the S1 too when using thin spurs. I've used one black and one white with some spurs.

Ah ok, so the difference is just the size between the two

Correct, the length is longer.

I have a normal width spur on mine and it gives the layshaft some side to side movement. Ive got about 2 dozen runs like this and havent seen any problems from it. It feels like it gives the assembly a bit of a 'floating' affect.

Default Gear diffs

I've mentioned this one before, but I'm not happy with the gears in the gear diffs. I run one in the front with 300,000 oil in. We have a tight technical indoor track on carpet. Today we had a straight which turned into a sweeper. I could see my front diff struggling through the sweeper, and when I got back to the pits the diff had gone. I've spoken to Xray drivers and they have never had issues with gears. I've put some carbon gears in and will see how they perform and how long they last. Anyone else had similar problems ?

My S1 build went great. No leaks no strip just as planned. Next weekend I'm going to break her in with a 17.5.

I keep either losing or breaking the small pin that holds the axle part of the Spec-r DCJs attached to the barrel. When the car comes off the track the pin and retainer ring spring are gone. Happened twice today. I did smack the pipes a bit so I'm assuming it's from that, but it was the same one both times. Is there a right and a wrong direction for putting on the retainer spring ring?

As a side note, I switched from a spool to a 1000k gear diff up front... holy immediate turn in Batman! Incredible respomse from the front end. I'm having to relearn how to drive as all my turnin points are now wrong and too soon. Crazy.

Yeah the retainer spring probably moved or come out and the pin fell out. Those retainers are horrible. I put a piece of heat shrink over the whole barrel and prevented any issues.

Hi all. New to the site.
I've been running Spec-R S1 cars for almost a year now. I really like them. They work well and the low cost is too much to pass up.
I run one car in Canadian Vintage Trans Am, mostly stock. It only has the aluminum steering, the floating servo mount, and R1 shocks. It works very well. It seems a little slow though. I have yet to figure out why though.

The other car I run in Stock Touring Car, 17.5 blinky. It has the option narrow 2.25mm lower chassis plate and the standard R1 top deck. I'm also using the R1 shock towers, floating servo mount, and TOP Photon shocks. This car is awesome!! The option chassis really woke this car up on the high traction carpet at my local track. Even with the plastic bulkheads and suspension mounts, this car is just as capable as some of the high end cars at my track. It competes against xray t4s, schumacher Mi5s, yokomo bd7s, Hobao h4s, and Associated 6.1 worlds cars and it can hang with all of them. That is as long as I'm not at the radio LOL!!

I recently pruchased an R1 and built it. It has the floating mount as well. Its set up to run USGT. I'm hoping it's going to be competitive. It's maiden run will be tomorrow. I'm super excited to see how it performs in comparison to the VTA car. Since I'm using the entire electronic setup from the VTA car in this new chassis, I should really be able to see the difference between the two kits. The VTA car is going to get my back up electronics put into it as I'm sort of putting that class on the back burner for now. I just want it functioning so I can let new people run it or just to have it around when I want to run an extra class.

The durability of these cars seem middle of the road to me. Not terrible, but I sure manage to break parts often enough. C hubs, steering knuckles and outer hinge pins are really the only things I break with any regularity. I have broken an S1 shock tower and top deck before though. The crashes that caused these parts to fail were pretty insane and I believe any car of any make would have suffered the same fate.

Anyway, long story short, Spec-R is incredible performance for the value. But you guys already know that!
