When is too many Lane Changers, "Too Many Lane Changers" ?
innocent.gif


I have a 32 metre (105 foot) Digital SSD track with 14 Lane changers 6 x XLC's, 6 x CLC's (4 x In to Out & 2 x Out to In) plus 2 Pit lane changers.

Oh! plus I also have 1 of the dreaded corner crossovers

just to make sure no one can just circulate in a single lane, "it's Digital, It's all about the Lane Changers"

.

So our track has a Lane Changer on average every 2.3 metres (7.5 feet) and I have just bought a new XLC and the question is do I add it to the track for a 15th LC or use it to replace a dodgy one (which I'll probably repair and look to add it in anyway

) .

Whilst this sounds like a lot, I find each LC serves it's purpose as an overtaking/blocking opportunity when racing (especially with 4, 5 or 6 cars on track) and also provides plenty of options to pursue the best racing line for fastest lap if your favourite line is blocked by another car during a lap. I certainly adds to the entertainment when the racing is close and the battle for track position is on.

So I am guessing 15 LC's on a 32m layout is quite a lot, but thought I would see if there were any other Digital "crazies" out there who might have more (here's hoping or I may need specialist help with this hobby

I use 2 to 3 depending on the track 7m 2 XPC's, 9m+ 3 XLC's. I guess its better to think of it in time. My small circuits have about 5 to 7 second lap time,s with my car standard so about 2 to 3 seconds appart. For reasons I personally never understand bigger tracks have lap times much faster than there length would suggest, proably as they for some bizare reason (to me) they have very few extra curves compared to my tracks. Hence a time value may be a betyer option to define an optimum. I did not include Pit LC's i.e the CLC to get to the pit lane,.

An average lap time on Frog Hollow Raceway is approx 12 seconds (good laps are 10 sec, record lap is 8.631 with Slot.it Audi LMP) so ignoring the pit LC's that's about 1 second per Lane Change. Although LC placement provides for longer gaps in sections and then really hectic stuff for the hardcore overtaker 😨

The main weakness with the LCs is the deadspot caused by the flipper. If you listen carefully to the sound of the car's motor you can hear the drop in revs each time one passes over a LC. Having a high number will increase this effect, however, it will be the same for everyone.

Having the LC just before a corner can assist in working out the braking point but it is not as good as a clean entry and exit strategy ....

Your choice of options in the poll are a bit odd..

1 to 2

3 to 4

the 5 to 9?!

I don't have a layout up that often but when i did last year I think I had 4 but would have put in more.

My guess is the length of the track was about 12 meters...

Yep agreed, but the more experienced the racers get the less impact that the dead spots cause, I guess everyone is travelling quick enough to avoid stopping on a flipper.

That said I really want to test my electrickery soldering skills and complete the RikoRocket XLC mod to liven the flippers, especially the XLC in the pitlane which is the main offender.

Ha, good question!

In my digital version of vecbtbs layout (9 foot by 5 foot), I currently have 6 XLCs and 3 CLCs (2 used for pit IN/OUT). I'm shortly going to add another CLC before the pit straight to give drivers another chance to pit if they miss the Pit IN CLC on the long back straight...below is updated UR3 plan.

I like XLCs for many of the same reasons, fill your boots!

Having as many opportunities as possible to overtake or change lane is a good thing but I do not think it is a function of how long your track is.

It is more depended on the design of the track.

Especially with the scalex xlcs, you have to make sure that the cars will not miss the sensors to avoid changing lanes when it is not requested.

The other issue is that when two lane changers are too close it is difficult to be precise and sometimes you might use the wrong one.

I tend to design my layouts in such a way that I can have at least 2,5 straights before almost each significant corner. On long straights (more than 3 meters) I might put a lane changer at the start (after a full straight piece) and at the end.

I had a number of CLCs on the main circuit. However I got rid of them. Perhaps it was inexperience but cars seemed to have a problem of comeing off (bad driving) but had the unfortunate effect of shorting the powerbase, hence I goot rid of them. They ar OK as a pit entry as you are slowing anyway on my designs, so coming off is not an issue. I did try the Diode trick to power the dead bits of the CLC but it unfortunately had less effect than I had hoped, I often wounderd if you could have a capacitor in the system to put more than half a cycle into the dead bits.

We have 5 straight LCs on our 20m club track plus a 2 lane pit lane.

The LCs are not evenly spaced. We have a complex of 2 compound curve hairpins that split up 3 of the LCs - it is a major overtaking section made far more interesting by the LCs because they do not slow the car down whilst lane changing unlike an LC in a fast section. So it means you can pick your overtaking line and try to block a faster car coming up behind you but as there are 3 LCs quite close together the chances of second guessing the guy behind you at every overtaking opportunity is slim.

The 4th LC is in a less technical section and helps line you up for a blast into the long straight but is at a point that you dont have to slow down to lane change. The final LC is between a couple of wide radius curves that build speed into the long straight - it offers an opportunity for the brave to dive around an opponent but its primary purpose is a last-chance lane change for those wishing to pit. This section does require you to slow down to use the LC unless you have a car that is very stable so it tends to be used only for pitting and for last-gasp attempts to steal a place in the final seconds of a race.

The fast straight and a fast R4-R3 slow-down curve (which account for about 7m if the 20m total) have no LCs - this is very high speed and nobody would slow down for an LC even if there was one.

Lap times vary by class between 7s and 10s. In our fastest class you get 5 options to change lanes in the space of less than 5s and you can use the 2s on the long straight to glance at the 32 TV to take race data on board.

Lesson? Put LCs where you can benefit from using them - often that is not the even spacing that logic might suggest.

Holy words. Useful Is Better.
35mt D132: 4XLC, 1SLC, 1CLC (out to in) + pitlane.
16mt SSD: 3XLC.
