Please put all notes and comments about the upcoming RevoSlot Group 2 Rally series.

After spending some time preparing both my Ford Escort and BMW 2002 I have some information I would like to share with the group.
It helps the cars body float if you use the optional brass flat head 1.5mm body screws. RevoSlot Part RS-213b
It helps to have the front body screws tighter than the rear screws to keep the rear tires from making contact with the inside of the wheel wells on the body.
Be careful to not true the front tires too low. With the guide inside the chassis as far as it will go, the stock braid, and un-trued tires the front tires barely make contact with the track. If you true the front tires any lower they will no longer make contact with the track and might cause the front of the car to tip.
Using NSR super thin braid, removing the spring from the guide and tightening the guide up all the way, the front tires barely touch the track. If you true the front tires too much they will not make contact with the track and your car will tip from side to side on the guide.
You will have to glue the rear tires to the rims as the tires can peel away from the wheels under acceleration.
These cars use a unique 14mm wheel. The only tires that will fit on them are replacement RevoSlot tires so don’t spend any time trying to find alternatives.

Paul Gage has urethane tires sized for the Revo grp 2. They do not have the central rib, so may be tricky to mount properly.

Paul Gage tires for Revoslot Grp 2. Mini-review.
I decided to order some Paul Gage urethane tires sized to fit the Revo Group 2 cars. The order came from Slot car corner, both the softer (XPG-1780SM) and harder (PGT-1780SM) tires.
These tires do not come with the interior rib of the stock tires, so I wanted to make sure they were mounted on the rims fairly true to begin with. After slightly roughing up the wheels to provide a “tooth” for the glue, I wiped down both the rims, and the insides of the tires with some isopropyl alcohol. No issues with the solvent reacting with the urethane that I noticed. I then started the tires onto the rims, taking care that the open pour side of the tire was facing the inside. I pushed down on the hub to seat the tire squarely on the rim, and gave them a test spin on the truer (without tightening, to avoid nudging the tire). The hard tires were trickier to get on straight, but it only took a little bit of fettling to get rid of the wobble. Tires successfully dry-fit.
On to gluing.
The method I used was to use a tiny bit of the black C/A on a toothpick and running it in
between tire and rim. Usually took 2 reps of this per side. I glued the backs first to get the tires properly registered on the rims. Waited a half hour, turned over the wheels and repeated the process on the front. Note: I have had experience with Shoo Goo not curing properly against urethane, so I avoided it.
On to truing.
Truing urethane tires is a breeze compared to rubber, the process is a matter of minutes, not hours. The material is much less sensitive to heat, and cuts more easily on my Hudy truer than the stock rubber tires. The Paul Gage tires also do not have that seam down the middle of the tire, and were much less out-of-round than the BRM tires. The Paul Gage urethanes are not softened by lighter fluid, so the usual polishing method will not work, I did get them smoother by wet sanding with Tamiya 1500 and 3000 sanding foam sheets. They never did get that “Just sprayed with armor all look, though.
Performance results. Some surprises
I ran both my Alfa and My Escort at 11 volts on my Spottswood track (yellow lane). Each got to run 60 laps with each of the tire choices. Here is what I got:
This test was me driving (and all that implies) and on my track. The rally track is a different animal, and this may not reflect these tires behavior there, but I would like to lobby for making them legal for the GRP 2 event coming in spring.
I expected the soft tires to do better, but they were the slowest of the lot, and they wear like old Dunlops! The stock rubber tires are the grippiest, but the harder urethanes feel very controllable to me, and they did get the best time.
Thanks for letting be prattle on about this.

Thanks for such a great article. I really appreciate you taking the time to put this together.
The last time we ran the RevoSlot Porsche GT2’s we had some issues with the stock tires. In light of this, I tried the Paul Gage tires for RevoSlot cars to see if they would work any better. I discovered almost the same exact performance on our main club track as you had on your Spottswood circuit. The harder ones were easier to control but the softer ones had slightly better grip while the stock tires were the best all around – with the exception of their degradation issue.
I don’t know if we will have any wear issues with the stock RevoSlot tires on the rally track as the speeds and acceleration out of the turns is so different.

I do hope the urethanes will be allowed. Especially since we are getting more flexible with tire choices in other spec series like

Hello? Anyone there? Dave?
Would like to discuss having the option of Paul Gage Tires. Especially with how out-of-round my Revo tires have been.

I will run one or the other of these. Leaning towards the escort slightly at this point.
i used to be able to post photos in the body of the msg, but that option is missing now.

I believe I will be running this Ford Escort.

You guys know I have to ask – White kits allowed? One of my friends is a graphic designer and wants to do a wrap on one of my cars. I think the shapes of these with less curves and larger flat surfaces lend themselves well to that.

That’s awesome, Mel! I have wrapped a car in the past. A BMW Group 5 M1. If you are willing, can you weigh the body before and after the wrap is applied? I neglected to do that with my BMW and have regretted that oversight, as I wanted to be able to compare the weight of wrap to that of a couple of coats and paint and a clear coat.

Absolutely! Can’t wait to see it. Brian is going to do one of his famous hydro dip’s that I can’t wait to see.

I talked to Dave C, and urethane tires will be allowed for this series. Please revise the rules to reflect this, thanks 🙂
