Question Pablo. When you say no welding marks are you talking about burn marks from the chassis shorting to the track braid?

Yup. See the photos in my post #111. Whatever you want to call it, if it causes pits in the chassis it is, IMO, most certainly capable of doing bad things to a $13 motor.

 

Not a plug for the skin product, just letting you know my mindset when I opened my wallet and bought one :to_become_senile: I like mine for sure.

Next step - motor examination. Using geezer goggles over my 3X reading glasses, I shine a light at the comm area.

Brushes are about 75%, comm track is even, don't see any obvious problems, wire color looks like new.

Gears look fine, BB's still good, axle still straight, no broken solder joints. Ready to race again.

 

Note the keepers on the axle, made by cutting the hubs off old wheels - they cost nothing. Next race, I know the wheels will be in perfect position again.

Pardon my jumping ahead a little, but I have run out of bulletproofing.

Took a piece of painted 7 thou Lexan and placed double sided wing tape over it.

The result is, slightly thinner (lighter) than store-bought stuff, and works fine :ok:

With all the attention to detail on chassis and body setup, it just makes sense to check the body clips also.

Flag clips, flag, and washers cleaned. New Prime braid trimmed and ready.

 

The flag shaft had a sliver of loose thread near the base, which I removed. Checked for cracks, then a pass through my flag sander gizmo.

 

The flag had 20 thou of spacers underneath and a spare 10 thou up top. I'll add a 5 thou under.

Now that I'm done reading my scum pattern, time to clean up and check the chassis.

 

I checked for 2 things on the bite bars:

-straightness (one of them had a very slight tweak)

-"paper clip" ends bent slightly up so only the bar itself influences the chassis

(in other words, checking to ensure they are exactly the same as I made them in post # 14)

 

IMG_5562.JPG

 

Pan section was very slightly tweaked in a couple places and only took a minute to make it flat again.

I also ran wires (.039" front and .047" rear) through the holes to eyeball proper athwartship alignment - it was fine

 

IMG_5564.JPG

 

Center section had a very slight tweak and was also easy to fix. Tongue tilt checked in both axis and it's still good

 

IMG_5565.JPG

 

C43 steel is harder yet seems easier to work with compared to Cheetah chassis. Better memory? :)

New lead wires - these white ones from PCH are OK for a race or two, but not near as good as the old Alpha white.

Note the insulation already failing on the positive wire where I bent it - this would not happen on quality wire.

 

IMG_5569.JPG

 

It will last a race or two, just like the yellow did. I'm open to suggestions on a new lead wire that makes me happy.

C43 ready for battle (again). In summary, it was a simple inspect/clean-up/fine tune event.

 

IMG_5571.JPG

 

The new Warrior body is very nicely made, consistent thickness, cut lines clearly marked, easy to mount and trim.

 

IMG_5574.JPG

 

Having a clean, prepped car at the start of a race doesn't guarantee success.

But I wonder how much care the competitor's cars had before the power comes on.

 

Confidence gives you an edge. Hope some of this info helps you, and good racing.  :)

Pablo... thank you for the write-up.

 

Two quick questions...

 

Have you tried the new aluminum pan for the C43?

 

Is there a particular reason for putting the "J" end of the J-Bars on the same side?  Or, just coincidence?

No, and I probably won't, since I feel I have plenty of speed. Where I race the limiting factor seems to be passing lappers clean.

 

As far as I know, makes no difference which side the paper clip end is on. Other than having the up bend I use on the correct side.

 

My take is, the paper clip bends are not intended to do anything other than make installation and removal easy and quick. They do that job well.

That is correct Pablo, just to retain the bar and be removable. The bar, and not the J should be the "active" component.

My C43 car update, today at The Dungeon:

The car was as fast as anything on the track. Zero problems.

 

Warrior 7 thou GTP body performed fine. I didn't sense any significant speed advantage or disadvantage over the competition.

The body itself is still in almost perfect shape despite the usual hard hits and retained it's shape better than most bodies I've used.

As we were talking about the C43,
last weekend we held our last 3 hour team endurance race before our summer break. My teammate and me finished second only 5 laps behind the winners. Our brushes were worn out just 10 minutes before the end and the motor slowed down when we were leading with 8 laps  :dash2:  :crazy: . But it was very amazing and a lot of fun!  :good:
 
I just was at my workbench and took some pictures:
 
This is our car after the race:
20170507_212805.jpg
20170507_212824_k.jpg
 
Scum pattern and burn marks  :D  (we were a little bit too low at the front, it is a flat track with one banked high speed turn; difficult to set up the car)
20170507_212857_k.jpg
 
And of course you have seen this is TQ lead wire  :laugh2: , don't know where I have this from. Must be from my teammate.
So here is our T-car with my lead wire:
20170507_213109_k.jpg
 
And I just picked some new wire out of the bag, the brand is called "Muldental Elektronik".
20170507_213333_k.jpg
 
I modified the link in the post above, maybe now it works.
 
Just found a short video from the race:

Keeping up with the Jones's. Or in this case, with my Dungeon racin' buddies  :)

My sexy C43 gets a new JK aluminum pan and a new Renegade body.

 

Sanded everything top and bottom, but didn't find any burrs.

A few easy tweaks made it pretty flat. Total time about 5 minutes

 

IMG_5990.JPG

 

Cleaned the bottom with lighter fluid and layed the new Ralph Thorne pan skin on.

Piece of cake. And since they came in packs of two, I didn't have to buy a new one :sun_bespectacled:

Trimmed some fat from both ends of the pinion

Click, click - new pan is on.

I love these Cahoza 72P 42t 16 degree spurs so I slapped a new one on just to scare Bud 'n Red. :wizard:

Renegade GTP body has nicely defined cut lines.

I like the recessed lower edges – makes room for taping the clips without a bulge.

Easy to mount and trim, looks real sharp. Can't find anything about this new body I don't like. :)

Paul,

 

Why such a tall ratio?

 

What sort of track are you running on?

On my home track which is a tri-oval I run 15/36 with .750"-ish size tires. Some use 16t pinions.

I run 10/28 on my Can-Ams.

Pablo this is why it's important to understand the differences in environments people run in before duplicating or discussing setup. Zip's home track is 53m (170 ft) totally flat, with maybe 11 corners, not blipping but and hard braking into and hard accelerating out of. "Point and squirt."
 
Good set-up for fast times with what you have there would be 64p 11/37 with .670" tyres (edited) ON HIS WELLINGTON TRACK

Pablo,

You're very aggressive today. I'll edit/clarify my post so you get what I mean. In the meantime don't be a wanker.

The Renegade body worked very well today. I'd consider it an improvement over what I've been using for the following reasons:

-thickness is consistent, cut lines are well defined, nice contour features, easy to trim/mount/pin

-seems more stable when passing slower traffic

-holds up well in crashes

-masks are better quality

-the winning car (John Clow) was using one (on a C11) and he agreed it was a step up

 

JK C43 aluminum pan, I'm not sure yet if it improved lap times over the steel pan, as the timer had a glitch today.

This isn't a discussion on set-up, swodem. It's a build thread in my own personal subforum about my car.

So you lecturing me on protocol is ridiculous. Zippity's personal situation has zero bearing here.

 

You want to call me names like "wanker," do it in a PM. You want to bicker about gear ratios, start your own thread.
