Revo guide breakage

[modelersc]

Hi all
I'm happy to be part of this Revo proxy. Best car for the money anywhere in my opinion. The club I belong to (IHSR) is running a Revo proxy currently and the competition is excellent but we've experienced a problem that may develop in this proxy too. The guides have been breaking for some reason. Perhaps its over-rotation during a spin but its happened more than a few times with our cars. It does seem to be a driver-performance issue more than a material issue in my opinion.I would hate to see a "known" issue have an impact on this proxy like we've experienced.

I'd like to respectfully suggest that the cars should travel with a small supply of replacement guides and that the hosts be authorized to replace a guide as needed. There should be no penalty to the car if this happens. I'd be happy to help fund the aquisition.

Thanks
Sherman

A few minutes work on the guide tongue, with a round file, or a burr in a dremel, to allow a few more degrees of guide rotation , will resolve the issue.....easy and inexpensive !!

That might help for sure - but is it legal.? The rules say no mods to the chassis so I dunno.

[chrisguyw]

That would be Tony's call.

I'm part of the IHSR Revoproxy group. We have had 3 cars break guides through 5 races. Two were Porsches that broke on a straight that had a slight bump and a Marcos broke from overrotating in a spin in the corner. The Porsches were generation one so the plastic is older but the Marcos is new. The guide were rounded at the front of the guide and non of the cars had added weight. I talked to Alan Smith about this and he suggested trying BRM S-026SS guide. It's a slightly different profile but is made of a softer plastic. I just heard about this proxy today so don't know if I'll enter but you should be advised that guide breakage could come up. Otherwise great cars! ~Ron K

Insufficient guide rotation, has been the cause of guide/and post hole breakages in many brands of slot cars over the years. Tons of Scaley, Fly, and slot-it cars have broken their guides or guide tongues due to this............the Revos' will not break their guide tongues (metal) , so the guides are the weak point, and will break. You could try a potentially stronger guide, or ,you could fix the issue altogether. A few minutes on the guide tongue (with a file or dremel) allowing a few more degrees of guide rotation will fix the issue,........quick, inexpensive, permanent, and, a better performing car !!

Not to start an argument but we're 11 races in of a 12 race series and we've had no issues whatsoever with our guide or anything else for that matters. FWIW, we'd all switched to the deeper guide - we run on Carrera and wood.

[War Eagle River]

We have been racing RevoSlots since they first came out. Permanent fixture in our rotation. Over 40 RS cars in our group, running on 3 different tracks. Never had a single guide break. We do run on wood tracks with the deeper guides that are provided by RS.

I have 10 revoslots, several makes but mostly Porsche GT2's. I have never broken a guide on my 77 foot wood track. The IHSR proxy is on 10 tracks, 7 wood and 3 plastic tracks. We decided to run the stock 7mm guide to prevent binding issues on plastic tracks. I ran the first proxy race at my track without any issues. We have run 5 races so far and have had 4 guides break. All of the races so far were on wooden tracks. Some of the broken guides were profiled at the front of the guide, some were using the spring with the guide. The only common factor is that they all ran the stock guide. Maybe that is the issue.

I have just a few Revo cars, but I use the provided deeper guide and use a Dremel to trim the opening in the frame to provide more guide rotation. My track is only 44' has has some very tight turns, so binding is a problem, as is guide breakage.

[modelersc]

So is trimming the guide hole legal or not?

[Brumos RSR]

We will not modify the chassis at this time.

About 10 years ago we ran a Retro race on a 155' King track that a guy built. We were breaking guide flags left and right. Turned out he had routed his recess for the braids way deeper than needed and the guide flags were hanging up in the recess and weren't able to break away from the slot.

Just saying, if it's only happening on one or two tracks the problem could be the track.

[Rastas]

I've had one brake on my Supra for know reel reason.

[Kevan]

More like an obvious reason, back end slid round far enough for the guide to hit the chassis, back end still continues to slide round and is stronger than the guide...end result, snapped guide.

[Kevan]

After a few hundred laps the guide on my Marcos broke, replaced with a Sloting Plus guide and made a bit more clearance on the chassis to prevent further breakage. They can and do break as seen in this thread.

[Rastas]

I've done a lot more with no breakages is what I'm saying! Kevin.

[War Eagle River]

I still don’t understand what you all are doing to break guides? I literally have multiple thousands of laps on all my RevoSlots, 12 of them, and have never had a guide break, let alone anything else. We ran a RevoSlot Endurance race, putting close to 3000 laps on each of four cars in the race, and all the practice laps with those cars and others. There must be something that is causing the guides to break...your driving, the track, something else? We have over 40 Revos in our group, never a problem. Are you all still using the spring loaded guide? Could that be the problem? Have never heard of this issue until this thread started.

[Kevan]

Not using a spring loaded guide, standard tyres, standard motor, standard gearing. They go great until you go beyond what they should really be capable of. I'm one of the best drivers in our club and not prone to breaking stuff through lack of ability. Maybe it wouldn't have broke if I wasn't racing against NSR Moslers

[modelersc]

Its clear there are two schools of thought here. One thinks there is or probably is an issue ......and the other hasn't seen an issue so perhaps its driving style.

In this proxy there will be a lot of people driving a lot of unfamiliar cars- so if there is an issue, its sure to show up under these circumstances.

Whatever the reason, if it does happen its sure to ruin someones race over something other racers have pointed out- is possibly avoidable by opening the guide hole. One ruined race would be a shame but if we don't have a couple of spare guides with the cars -just in case- more than one race could easily be affected.
Me? I'd rather see cars racing than sidelined- broken. I'd be happy to send spare guides if we allow this repair when/if needed.
Anyway, is the hole adjustment legal or not? Just askin'. I'd like to get my car finished and shipped.
