  1. Cheers Ritchie, have a good one yourself Gentlemen, trolls, triffids and anyone I may have overlooked, results from last nights war games. BTCC Results BTCC best laps Muscle car results Muscle car best laps 65-80 Sports results 65-80 best laps
  2. Back in town. Okay, Oakland this week, we’re back to week one on the roster. Doors open from 5:30 1 BTCC (British Touring Cars Championship) -[ Modern ERA Scalextric models - MG6, VW Passat, BMW 125, Honda Civic Type R] 2 Muscle Cars 3 1965 to 1980 sports
  3. Bit concerned about that timing system Pat, it keeps writing "reptile" up the top of the results. Love that Falcon of yours Pat, better still, it goes as great as it looks. Wish I could find replacement wings for my Falcons, they both went missing on race nights, one at Mac's early on, the other, who knows where - I forgot.
  4. It isn’t even “electronics” Greg. It is a basic electrical principle, and the same principle that makes a motor rotate when you apply voltage to it - simply the flip side of the same coin, and it is something that people normally learn their first month choosing motors etc in club racing. I find it hard to conceive that a guy who debates the finer parts of alternative digital systems electronics across the forums is sitting here pleading ignorance on the basic principles of motor braking. And it is not about “not upsetting those who are good with electronics”, it is simply about not writing wrong information that would create confusion for new spotters.
  5. I’m in. 2 classes are sorted-ish. what time do the doors open Paul ?
  6. Mr Flippant, you just did the same thing. Power is not “going back to the motor”. for you, Den, anyone else reading this thread, it IS important to understand correctly how this works, or you will not understand how the addition of resistance to the circuit works, thus reducing the motor generated braking, nor the impact of swapping out one motor for another with a stronger magnetic field/higher torque - and thus stronger braking. Den - yes, I’ve come across tracks with a 25 or 50 ohm pot wired into the stations. But I didn’t know some Tassie tracks had that facility. when I originally designed my controller stations, I put in a hole in the panels, for a pot to be mounted and offered that as an optional extra…but after a couple of years I only ever sold one set of stations with it…. Ah well. worse, we had a guy in club who sometimes wired his motors wrong way round, so would flip over the DPDT direction reversing switches - and not flip them back when he moved to the next lane
  7. That's weird SportsRacer - your controller image has disappeared. - So has r377. I spent some time writing a full and definitive reply regarding his issue, [Phil also took some time] and not a bean back since, in 2 1/2 months. Den, what you wrote there is not quite correct. Nothing is "applied" to the motor, the circuit simply becomes a dead short, and so the motor itself attempts to become a generator - into a dead short - thus causing the fixed magnets to resist the rotation of the armature caused by the rolling of the rear wheels moving back through the gear train, which is generating a conflicting magnetic field
  8. from last night. Thanks Mac, those cortinas were a blast. 5 lap spread for 4 teams over 72 minutes race time, so close
  9. I’ve decided to try something new this week - Maintenance Degreasing… cleaning, oiling, repaired a broken body post (only been broken since 2019), glued a wing in place (yeah that wing on the V8…..) Even changed a gear and a guide…. Be impressed, be very impressed, - after all it may not occur again this side of the next apocalypse
  10. Your usual excellence Mike
  11. Hi guys results from tonight, and a quick bit of video from the Minis. Pre 65 laps and times Minis laps and times Group C laps and times
  12. I have built a snorkel rack and drying station ….. actually it has stopped raining here now. my main curiosity is how much longer Jasper can keep his legs crossed, he hasn’t been outside for a potty break in over 24 hours
  13. I cannot possibly argue with that Except them ain’t smurfs, they’re a selection from the FBIs most wanted list
  14. I am near as to cured, so we can meet at Oakland this week Classes Week 2 Pre 65 Sports Group C GT1 If I get motivated, we may swap out one class for a house set of something…
  15. I have no argument with that, all that is happening, is that the urethanes are depositing material onto the track surface, which sticks, and aids further urethanes to grip to the "doctored" track surface. But the usual charges against silicons a ) "laying down a film of silicon that ruined the rubber grip"orb ) "removing the build-up of rubber" (by making it stick to the tyres) Are both untrue. In fact, if you used treated soft rubber tyres after the urethanes - the same thing would likely happen. If you routinely used treated rubber tyres, then switched to urethanes - a similar thing would happen. But if you run a clean track - you can run any combination of tyres that you wish, without the slightest issue of incompatibility between compounds/tyre types. BTW - I didn't mention before but Bright coloured tracks ? That comment showed how absolutely little idea you have about the NZ slot scene. Having supplied the braid, router bits and timing systems for around 120 tracks in NZ, I feel I have a reasonably good handle on the market and hobby here. There was ONE - I repeat WAS just ONE blue track built by Chris Wong in 2009, with a 2 pot gloss surface in a pale blue. (and a very nice track it was, factory built at a furniture and caravan company, it raised the bar on track quality.) That is the only track I could imagine fits the description of "bright" . Chris' track has been mothballed for several years, as the magnabraid rusted after it was moved to a waterfront location. FWIW - I don't know of any clubs running silicon tyres in NZ. I sold about 10 packs of Slot.it S1 and S2, and a few packs of indiygrips and max-track the past few years, and about 50 packs of my own urethanes, versus about 25,000-30,000 packs of soft rubbers from the 5 usual suspects. NSR, Sideways Slot.it, Policar and ScaleAuto
  16. I have some background in the chemical industry Paul, I went through this a decade ago when it was a hot topic, and utterly destroyed every false premise about silicons Just for a start - they are chemically inert and stable. There isn't even any solvent commonly used around slot tracks which can affect or degrade them. That is why similar silicon compounds are used as valve seats and seals on the valves of IBC tanks containing aggressive, acids, alkalis and petro-chemical solvent cuts. I could tell you stories about the wrong seals being used on IBC tanks and pipe fittings, and the resulting port closures, factory evacuations, but you'd lose interest quite quickly. They do not shed any "film", they do not magically spit out a portion of their simple inorganic compound, and anyone who says otherwise is simply acting off false interpretation of what is taking place in their track environment - to their detriment and continued ignorance. At the time I was "proving this" I also conducted solvent tests, just as demonstration; so best you leave the subject to those who act out of facts, not myth. FWIW - what I HAVE seen, is that tracks which have been rubbered up - especially with tyres using treatments, when the rubber “goo” builds is sticky, IT can stick to other surfaces…. Eg such as silicon tyres - but also to urethanes, steel rollers, plastic tyres etc, but it has nothing to do with silicon per-se, only to to with the way the track has become coated, and what with, from rubber tyre use and -in most cases - form of tyre treatment essentially - a misdiagnosed problem, with a solution which resolved the issue - but not through understanding, merely by removing the perceived cause.
  17. Actually, that silicon thing you mentioned is an old wives tale anyway. Our club and some national events did run silicons for about 2 years, alongside assorted rubber tyres on our routed tracks. I never came across any instance of silicons. a ) "laying down a film of silicon that ruined the rubber grip" or b ) "removing the build-up of rubber" (by making it stick to the tyres) I did when running an international proxy come across instances of plonkers cleaning their silicon tyres with all sorts of solvents between heats, (resulting in a pink film on the silicons as the solvent dosed tyres collected, and reacted with rubber on the track surface and stuck the whole shebang to the tyres) We simply gave up using silicons because we could get more consistent, and higher grip with treated soft rubbers over time, especially with tyre treatment. Plus all lathes could do a good job with soft rubbers, whereas silicons took up to 12 hours on a lathe if you had a sandpaper drum/flat plate versus a diamond or hard still abrasive drum. It is more likely that the treaded tyres on that car just happened to rough up the surface, or in some way are pulling rubber build up from the track surface through abrasive action. You would be able to tell pretty quickly if the tyres were silicon - they would resist cutting, and would be impervious to treating with any solvent. You could "clean" them with say fuelite. If they react, they aren't silicon
  18. I am unlikely to be recovered by next Thursday. Apparently it isn’t man-flu, I am actually sick, according to the lady-quack we saw today. Pat, you available to host?
  19. I am diseased. Some combination of SARS, EBOLA, COVID, Bubonic plague and Man-flu. Glenda says it is merely a common cold... but you all know how unsympathetic our wives are when we are dying by degrees. Anyway, best I stay away, as we don't want the whole club in quarantine.
