How To Improve On Position #38

Recommended Posts

As you are all more than aware I finished a very poor #38 out of 42 in the SCX Rally 2012 - I thought i had a pretty good car but it was obvious after the first few rounds that my car simply didn't cut it. Still the constant pain and suffering throughout the 2012 season gave the missus plenty of ammunition.

 

I've decided to try a slightly different approach for 2013 and have already started selecting the gun motor from the few cars that I was able to source.

 

I bought one of those digital taco's and simply put the slot.it gear on the axle and measure performance.

I'm curious if everyone ran 4x4 during the 2012 series or can I remove the pinion and shorten the motor shaft?

Mark, they've got to stay 4WD for the SCX Proxy.


Computers. They'll never catch on.

What did you get Mobz?

 

2012 Rules are here:

http://www.auslot.com/forums/index.php?/topic/14448-2012-scx-proxy-wrc-rules/

 

Essentially:

 

- trim chassis/wheels arches

- glue motor

- true tyres/wheels (control tyres for 2013)

- swap braids for SCX Pro braids

- find the best motor your can

hey miveson

i just picked up a Ford Escort RS Cosworth 'Michelin' #1 from armchair.

 

i'm not really expecting to go any good, just keen to be included

i think i can handle those mods :D

dont know about chasing engines...i dont think i will go that far, although i do know where to source a few ;)

 

i'm sure i can......but i can repaint right

The 2013 rules, when posted, will basically be the same as last year but with a control tyre.

 

The cars are 4wd and must remain 4wd via the RX-81 motor, with all 4 wheels turning

You know the Escorts not included in the class

cmon mark...you know better than that....touch wood ;) ;) :lol:

 

so by the mention of livery in the car list thread, does it mean no repaint?????

2012 rules ........ http://www.auslot.com/forums/index.php?/topic/14448-2012-scx-proxy-wrc-rules/

 

Body & interior

  1. Body must be mounted with body screws and be easily removable. Tape or tacky clay may be used to keep loosened body screws in place
     
  2. Light sanding/trimming of the inner wheel arches is allowed, but the body must look original on the outside.
     
  3. Trimming mounting posts to adjust ride height is permitted
     
  4. Light sanding/rounding off edges on the interior tray is permitted.
     
  5. Antenna and mirrors may be removed
     
  6. Lights and parts in the light system may be disconnected and removed, but outer lenses must remain original, or replaced with something that looks like a lens
     
  7. Electrical connectors between body and chassis may be replaced with wires (require soldering)
     
  8. Interior must remain as original but can be repainted. Must include a navigator
     
  9. Re- painting of the body is allowed. Fantasy or obscure rally liveries are encouraged.

Can the posts on the interior that locate the axle bearings be cut off to allow body float?

As with last year ..... yes!

I did noticed a few that potentially the tyres could rub on the body, especially those that had a bit too much float.

 

As well as keeping an eye on that the two other things I observed with the great cars V's the good cars were:

You could could get free movement rolling the back wheels - usually a well run in motor and gearing and the guide moved freely when pushed up against the chassis. Many were biting and this IMO caused de-slots on the tighter corners. As well as all the other basic set ups. Remember each deslot costs you around 2 seconds

Mark,

I am interested to hear what your motor comparison shows up. I don't feel it can give any benchmarks without Torque data too however, just an understanding of the degree of variation in RX-81's would be interesting to know.

Does motor spin (by hand) more freely than the others

The two higher rpm motors spin much more freely now, but that's more to do with me running them in over the last few days, they are significantly smoother than before.

 

Out of interest I took last years Subaru motor and tested it @ 11900.

 

I looked a bit further at the Subi and in dismantling it I discovered that there were some pretty obvious issues with it.

 

- The pinion on the front gear had a completely worn tooth

- The wheels were ridiculously out of sorts

 

I'm not sure what to do with the wheels - last year I spent some time truing both the wheels and the tyres but then I had nothing but hassles with the wheels falling off, even after gluing them and then it is obvious that gluing the wheels can mean that they aren't aligned perfectly on the axle.

 

I'm interested to know if anyone else sleeves the axle part of the wheel to reduce the possibility of cracked wheels causing issues?

 

I'll probably pick the best wheels from the bunch I have and sleeve them.

 

I'm hoping in the new year to organise somewhere to give the cars a test run.
