The SCX motor does not have the torque of a King!
If you are going to try some alternate gearing I would only go down to a 26 or 27!

Good choice of car! Th pro Audis have a good record in proxy's as they ae a good handler. The motor seeems to be about right for an event like this not too hot but certainly has enough herbs to get it around at a decent clip. Like all scx motors the car will brake very well so gearing is just about getting the car to be at a nice smooth pace. SCX cars i have had usually come with 9:27 gears or 3 to one. I am not sure of the garing on the pro Audi but there is no need to cnange to slot it gears as the scx pro are good stuff. As a general rule gearing them at around 2.7 or 2.5 to one seems to be where the experienced tuners have geared these cars. you coud simply put a ten tooth and go with a crown from 27 down to 25 depending on what you want or if you have a nine tooth on the motor simply put on a 24 crown for 2.66 to one. As always in proxy's make it easy to drive and pick the right tyre and you will be around the mark.

Cheers Trevor.

Thanks to all for the advice, I will experiment more with the gearing and see how I go. I am amazed at how much tuning and tweaking these things affects the performance, all I have ever done before is sand tyres and add a bit of weight, am learning heaps through preparing for the proxy.

Another tip,

My opinion on the power pick up on the scx cars is the worst design ever in a slot car.

check on rules if you can do this,i'd change to a lead wire set up with ninco eyelets and a race giude that fits.

Power pick up will not be a problem then.

That is really what Proxy racing is all about!

So true. Changed motors gears etc. Gone back to the original motor but changed the gearing slightly to give more brake for those smaller tracks. Hope the motor is not too hot but will take the risk. Watched a few cars that were "easy to drive" last year that finished mid pack and came to the conclusion they have to be fast too. It might be a bit too hot this year with the smaller average track but its just a risk i am taking. gone with a krahs 23k and 9/24 gears. Krahs is a big torque 16.1 watt motor from what i can remember so it really is a powerhouse. I had a spare shark 25k that i wanted to run with 9/26 gears but it died. I think next time i will spend much more time tuning.

SCX pro car does have the wire and eyelets style guide so that's a good step over and above the standard scx cars.
My pack of crown gears arrived in time for the weekend, also got some P3 slot-it tyres and Ninco pro race to experiment with. Lots of options. I tried the 27 crown gear with the 9 and while that was an easy drive it did not translate to fast times on my track. I took the suggestions on board and switched to a 10 tooth and that was better. Replacing the Ninco tyres with Ninco pro race tyres did not change things much but was starting to get quicker with the 10/27 combo. Running the slot-it tyres instead was a big improvement and times were getting quicker, car feels much better in the corners. The 26 crown gear was too much, car seemed to be harder to control kept spinning out when i applied power. So the 10/27 seemed like the go, however running the track at 11v to match the settings of some of the tracks and the car was sluggish, perhaps that's the scx motor?
I had a Spirit Le Mans long can motor out of my Spirit Golf and decided to try that as the SCX car comes with a long can adapter. Boy major difference both at 11v and 12v with 9/27 gearing, went quicker again and much easier to drive. I will try this with a 10 pinion and see how that goes I reckon I can squeeze in some more testing on the weekend and then it will be time for the final decision.

[lenny broke]

Here's my entry
a Spirit Reynard 2KQ with Plafit Pointer 9:27 gearing, NSR wheelswith MJK tyres on the rear.
the decals are a mixture of DMC from pendle and Stubbo numbers and rondels.

[manimmal]

very nice!!

i can't help but notice there are several cars in this years field that have seen the extra effort of a good quality livery.

[gzminiz]

i agree, i wish i would of taken more time to make sure my paint was better and the decals didn't break. Going to be a great looking field.

[terry]

nice car Lenny!

I agree with others,there are some great looking cars for this year,can't wait for the races to begin.

My car?

Just waitng for new tyres to arrive,then she'll be away.

Lots of zytek's i though I was being unique! Another good looking entry

Mine will be in the post by the end of the week. Here is a quick pic of the body. Spirit Reynard with the side air scoop. The colour scheme was what I had planned to use on my 2008 Proxy XJ12 for the Thunder Saloons. Since that never made it I decided to reuse the paint and the decals which I still had on this. The decals were Pattos I think meant for the Jag XJ220 but could be wrong. I have clear coated this with Pledge "one go" which seems a tad glossy but wanted to try it and see if it worked. So far so good if rather shiny.



The wheels will be slot it with an NSR King motor and slot it gears.

[Davnic74]

Some great looking cars there .

@ Antony you can never have to much gloss...

Hope to have my car completed tonight,then some more tuning.
ATM my B car is faster than the car I want to use

[Davnic74]

Some pic's of my 2010 entry, Thank's to Stubbo for the larger decals(nose and top of rear gaurds), the rest are from Patto's Mclaren F1 sheet.

I dare not post a picture of mine. I have to admit that re-painting cars and re-decaling is something that I am not the best at (& probably building proxy cars as well), so mine is stock liveried.

Maybe next year

BTW, good job guys. I am really jealous!

[triggy]

I love your livery Davnic

I am with you on that one Hoffy. Everytime i paint a car it turns to disaster. Mine is going in stock livery. I think between now and next year i will try one livery a few times to get one right maybe a simple one like JPS or pennzoil. I muffed the last JPS cars i did by buying the wrong paint.
