M-K racing/newbury rc winter championship
 

ok guys

i have some dates for you all to argue over

20th jan round 1

10th feb round 2

16th march round 3

i have decided it is impossable to not clash with everything but i think we should be ok with those dates

the plan is to have 3 rounds with 2 to count done on a scoring system which we will post before the event.

f1 / f2 /f3 gradings used with prizes for top unsuported drivers in each f gradings probly top five TBC

track will be again be designed by nick pidge and trish

and of course the timing gear will work this time ;)


the club will also be running on friday the 28th of december from 4pm so you can try out your new stuff or practice the cross over which ever way you want it

thanks guys Andy Bell

10th and 18th or just 10th fella??

Andy, can i enter all, but if something eg. hols come up would it be ok to cancel??
Can't wait for it!!!

Having spoken to Rob Nelson from BBK earlier today (at some length, lol) the miss counted laps at the GP were down to the location of the PT or handout transponders on the car. Please remember that only 10th 4wd cars were affected.
Now that I am aware of this issue hopefully we can avoid any problems for the new series. :D

RR.

things are really moving now, this meeting has really put the club on the map :D

all your hard work has payed off guys, see you there soon :)

sorry guys will take a couple of days to get the entry form up and running so dont panic about entering but lets keep talking about how awsome its gona be :D

no panic, just wondered if that was ok??
BIG JUMPS!!!!!:D:D you know you want to:p

Rob did he have any tips for placement?
I have never missed a lap with my PT, be it my 12th or 8th cars.
The only thing I changed the weekend was from a xx4 to a B44!

Will this be for 18th's as well?

The PT needs to be located on the top deck of the B44. This is where I had mine and did not miss any laps.
A couple of guys moved thier PT's to this area and thier problems went away. :D

RR.

*brings his 'Keep the cross-over and can we have a big wall ride' petition over to this thread*

:D

Im with Griff....big jumps please lads :D

Will be moving that then asap! thanks for the info.

Some of the guys that were missing laps have run there hand outs and pt's in the very same cars all year, nationals and regioanls and at club week in week out and not had one single missed lap. Please don't shout at me but I fear that if you relly on this to solve your problem you will be disapointed. Will you be running the AMBrc at club on the 28th? As I could bring our shortened loop for you to try

Between the CML Raceway winter series and the Newbury MCC winter series it's good to have a good run of local meetings to work and build on the driving skills.

I think I need it.

Ta.

Elliott 'cheer section' Hopkins.

we wont be running the amb loop we have a different system for week nights thanks for the offer though


there will spots availble for 18th 1 heat thats 5 spots i have 1 entry at the mo


thanks Andy Bell

Can you please post any specific information that you where given? Things such as minimum distances from certain items in the car (eg. motor, cells etc.) for example. Any particular height from the track surface that helps?

I'm not sure what most people do, I personally normally run handouts in the roof section / front screen of the shell as I feel they are a bit too vunerable in the wing. Is that seen as good practice?

Have always been told to run a PT off the main chassis deck away from motors and cells as much as possible (i.e. on top of servo in 2wd and either the same place or on top deck near the servo in 4wd). I would also have though that having it too close to the sensor wire on a brushless system might upset it.
If you can confirm or otherwise any of these it might help somebody.

The more info you can give us the less likely people are to have an issue, at all venues not just yours.

For the record I think all my laps counted correctly at the MK GP in both cars ..... however my friend had troubles.

After i moved Bathys transponder into his wing it counted perfectly. It was in the top of the body before.

Do not want to teach people how to suck eggs but this is how I see it. As the loop is in the carpet below the car then the PT or transponder needs to be as close to the loop in the car as it can get for a good signal. This car has a good layout for a PT as it has only the lower deck to get through and the upper deck if there is a loop on a bridge. http://img161.imageshack.us/img161/2082/img0258iy1.jpg
With handouts and a PT the transponder really should have the clearest view it can to the loop. So the position should be chose so as to have the least amount of car in its way.
With a PT bear in mind that with the power drain going to the motor that the BEC in a ESC can have a hard time and I would recommend always using a 4700uF 10v capacitor on the power supply to the receiver just in case (get them from Maplin electronics VH57M £0.61), and always have a capacitor if using the higher drainage 2.4GHz receivers. Or the MRT Bug booster is good as it can supply power for upto 3 seconds if the power goes. I know it is a pain to have yet another capacitor or device on the car but as Tesco says "Every little helps"

Another interesting tip bit that I just un earthed is that a PT sends it's signal stronger in a specific direction.

Using the pic in the B44 above as an example, the signal would be strongest above and below the car. If you mount the transponder on it's side the signal would effectively be transmitting out the sides of the car and therefore be a weaker signal for the loop on the ground.

it is highly unlikely that pt position was to blame, yes on individual cars it could be a problem but you had several cars, it is a very simple thing to blame the user rather than the equipment. as i did not see the track where was the loop in relation to the final corner? as i may have the problem sorted
john

Agreed. Mine was mounted in the shell as it has been all year, shown in pic below: -
http://www.oople.com/rc/photos/south.../NO5E1581.html

This does effectively place the transponder just above the top deck as previously recommended but it didn't count properly all qualifying. I moved it to the wing for the final and it counted but that is inconclusive as a different number transponder was used.
The wing isn't a good solution as it will get battered up there so where is the best place to put it for next time?

I would also suggest looking at the loop gap and the speed the cars were crossing it. On Sunday the cars were coming off a high grip corner and accelerating for the approach to a jump so were crossing the loop at quite a speed. This might also explain why it was only 4wd cars as they were able to carry more speed on the corner prior to the loop??
It might be worth putting the loop on an a tight apex next time to reduce the speed the cars cross it or increase the spacing. (or both??)

Really looking forward to the round now!!

Rob, thanks for the post, all info greatfully recieved!

John, the loop was close to the final corner and IIRC you were going from next to no throttle to lots .... I think I know what your going to suggest.

Can't see speed being the problem, we do higher speeds at CML over the loop!

Is the loop spaced wider apart there?
Speed will be a contributor. The longer the transponder is within range of the loop, the more chance of the loop picking up it's signal.

guys

i think the main problems were these the loop gap was at the minimum set at 300mm and as has been said cars were on full power at the loop.

also we had the slack or spare wire coiled tightly in the corner which i dont think was helping.

i think that we should have the problems sloved ready for the next one.

thanks for everybodys input though i do love how we all become experts when things go wrong this is a good thing though LOL


see you all soon entry form now on line link below

thanks guys Andy Bell

Just checked the dates against my more 'local' event for my region, and the January meeting clashes...(I think I will have to go to the more local one this time, since it is half the distance there and back of going to Newbury).

I may come down again in february, but will have to see... regarding funds..

Mark

I have booked in for all.

Thanks again - We shall get designing ASAP!

Think the transponder thing will be cleared up for next time, it does seem strange that they worked when moved location on cars, and it was only 4wd's that had a problem so all seems to point to location of mounting PT's to me?

Either way i'm sure we'll sort it, RobR has been speaking to Mr BBK himself so i'm confident they know what they're doing :D

Let's just look forward to the racing!

Sounds like it could have been a combination of things adding up, although I ran 4wd with pt and never had a problem...

Cheers
Mark

Sorry, but what are the F ratings??

What do I put down as my F rating??

hi cris

if you do tenth regionals you would get an f rating we have also added an ability section so fill that in dude i recon 8/10f1 5/7 f2 1/4 f3


hope that helps A

Isn't it the better the grade the higher the number?

sorted;)

When are you allocated the new f gradings, as Me and You(Nick) are F5's still;)

dont they start for 2008 ?? at which point Mr Griff you will be F2 !! ;)

yeah I think F grades run form 1st Jan based on your previous year.

Cosie you in theory are an F5 but your ability will be nearer an F2/F3 depending on how you get on with a 10th.

me to !!! wont be missing this one :D

Glaaaaaaad to hear it!!! No attempting to get your car stuck in the roof netting though ok? :D:D

I think i'm technically still an F3 for next year actually as i only did 2 regionals even though I won the F2's :(

Damn :mad:
Only jokin ;)

Im booked in! :D

Allan, ill take that as a compliment! :)
