[Col]

10th electric or 10th IC?

Electric touring cars don't do it as the motors/ESCs are already on the limits of temperature after 5 minutes.

Also it's possible that you could bump up several finals if you'd had poor qualifying, so you may suddenly find yourself needing 4 charged lipos, which few of us have.

For example say 2wd buggy. If you had a couple of fully charged 5000 mah lipos you could get 4 runs easily. I cant speak for other peoples 2wd buggys but mine isnt touring car hot after 5 minutes.

Also theres a couple of minutes gap between finals usually. Blast em with fans, dont do warm up laps?

Would give you a glimmer of hope if you had a really bad day. You could place somewhere better, instead of being eager to get it over with and go home.

i get what your saying ritchie..........can someone tell me why the 2wd buggy a-finals guys get 3 finals,where all the others only get 1 final.

Here's why we didn't do it the last 'n' times it has been discussed since 19-frozen-to-death...

It is incompatible with restricted numbers of cells each driver has. Each driver would need to have about four sets 'just in case', where they can get away with two now. In the past it was about round cells not liking the second or third run of the day, topping them up, etc.
It puts lots of additional strain on drive trains, motors and suspension systems that mean those who get a bump start spending more than those that don't.
It is incompatible with the control tyre Rules. Either you allow more sets (so people tactically qualify low and arrive at their final Final on a new set) or you stick to the sets you have and people fail to get their second/third bump because they are competing with people who are on newer tyres.
Some people get a lot more racing for their money, mostly because they couldn't drive as well in the four rounds of qualifying they were allocated.
Driving standards drop as the desire to get that first place, and the bump, overrides any thought of being sportsmanlike to the other guys on the track.
What's it for? If you can't put it out there in qualifying; if you can't prep a car so it doesn't break down; if you can't drive with the other guy in mind and avoid the accident (watch the top guys...); if you don't have enough to qualify in the final above, why should you be rewarded for those failures?

And, with that in mind, we voted 'no' every one of those 'n' times since 19-frozen-to-death someone proposed bump-ups...

We could do bump ups if we ran a pyramid system like they did for the Neo11.
This would give you time to add a little charge to your LiPo’s and also time to cool down.
I also don’t understand why we don’t run the national like the USA and other countries (but that’s another topic)

That's been about in Nationals for as long as I can remember.

If you're talking about the Mid-West series I know we try to run the series as similar to Nationals as the guys can.

The idea being if you wanted to do the Nationals then you have an idea of the format etc....

How do the yanks format it?

Sounds like my wife

it will never happen as electric will not run the same format as Nitro!

it is possible and has been run with electric off road using the pyramid / christmas tree system. Never tried it with on road.

it can be done with one pack because you have time to cool things down and charge.

no body tries to make the lower finals but it does give you a chance to make a higher final bet Tom Yardy wished there was bump ups at Kiddy this year.

it also means more work for the the organiser as cyristals and marshals have to be sorted out.

electric people do not like change is your other problem

Both points so so true.....

Can't imagine Tom was trying to get into a lower final.

And change is something some find very hard.

It's also a question of time ... race days are long enough for most anyway even with people like Stuart W' running the meetings in his usual clockwork fashion!!!

Think about it, If I can hold my finger against my motor for more than about 10-15s after a run I gear up (I like my cars part race car and part griddle ). I'd not be happy putting my car back on track within 10 mins of it finishing a race distance, I know many people who are the same.

With that in mind if you had to allow somebody in the bottom final at regionals (say a H final) that would be 70 minutes extra on the race day. If you weren't going to allow that sort of time you would be disadvantaging some people over others which obviously can't be part of any democratically arranged set of regulations!
All that is before you consider that you would have to run all 3 legs of the A at the very end of the meeting in case Joe Bloggs hearo'd his way out of that H final,that would mean another hour extra too.

Having done some rallyX and having had a few bad day with several bump ups I can tell you it actually can get really difficult to deal with .. concentrating for that long is hard work (at least for me) and on a couple of occassions I deliberately let people have track position just "to put an end to it".

I might be in the minority and I know I personally have never been adverse to change (I remember when we always did FTD and didn't have a tire rule ... thank god for nominated tires and round-by-round i say) but I just don't see bump ups working in electric racing.

Also finally god knows how your getting 4 runs out of your 5000mAh cells, I'm running 5500s and I'd be 95% confident I'd dump before the end of the 2nd run as even though we typically only take around 1800mAh out of the cells as the charge disipates the voltage drop seems to be more agressive under load.
I have my LiPo cut off set at 3.2V/cell and at the point my ESC puts the car into 'limp home' mode I have a rest / no load voltage of around 3.85V/cell. Putting that pack back on the charger sees about 3000mAh put in to fully balanced.

There is another point .. think about what people would do to make that last run ... how many would turn off ESC voltage cut offs to get a few more mAh out of their cells resulting in lots of LiPo's thinking it's November 5th?????

Please make this idea go away .. pretty please!

Im not saying it would have to be nationals but at some events it would be a nice quirk.

I dont think it would be a question of time. Bump ups at rally x meetings are like clockwork. Adopt the same, if you dont make it hay ho.

Pretty much most of the points raised could be at drivers discretion. No one would make you turn lipo cut off. Also if you cant get 2x 5 minute runs from a 5500 lipo theres something wrong..

The point about extra racing over others is kind of moot. The A finalists get more than all the lower finalists every time, so it would be a chance for those to get extra racing.
