Its strange to me that so many setups show using the 0 degree front caster blocks. The car seems so twitch and edgy with the 0 degree. The 6 and 9 degree blocks really seem to make the car much smoother and easier to drive.

I have my battery all the way forward almost hitting the servo. It is right at the tape slot in the front, I used the battery holder for the front underneath the top deck posts . I then added 3mm of shims to the rear for the top deck posts. I also redrilled the chassi so I can use a battery holder in the rear but it not needed. My speedo is behind my battery in the center of the car, receiver pack on the right and receiver and transponder on the left. Depending on what electronics you use you might need to add some weight to balance it out but not much. I also moved my center shock to the hole on the bottom of the tower instead of one hole up because of the raised top deck.

Hope this helps. I'd take a picture but Shmyka has my car

thanks, that is how mine is arranged.

i have seen some other cars at my local track with the battery all forward and the electronics midship. more forward weight bias seems all the rage, so i was curious if anybody had tried a more forward weight distribution.

compared to the competition, my car seems to be a little sluggish to rotate around short tight corners. i guess the question is, do i try to cut a tighter turn faster, or try to roll thru the turn with a longer smoother line. (a consideration is the groove is usually better on the tighter line, so i feel a little stuck on the inside line.)

M. Mobers posted his race report from the Snowbirds.

interestingly, there is a comment about trying to reduce traction rolls, but the changes resulted in taking away too much steering.

it would be instructive (at least for me) what changes were made, and changes you might have tried next to correct the situation. (this might be obvious to some, but not me)

Some things you can try to get more steering

Crc white side springs with 1-2 turns of preload, you'll need longer set screws
18 lb center spring
Long front wheelbase

When it ran my car with the stiff springs the long wheelbase had too much steering, I want to try softer springs(stiffer than stock but not as stiff as above) and the long wheelbase, I think this might be best.

I'm not sure what markus did at the race, I'll see if he can post something.

thank you for the insight!

i tried a shortened wheelbase and it seemed worse, i figured that it was an ackerman setting problem and just hadn't sorted it out yet.

somehow i assumed a short wheelbase would increase steering. there is a running joke with fellows i race with, "whatever change you think you need to make, just do the opposite" (pancars are different)

I cant say on a pan car I haven't noticed a difference with ackerman as long as I keep it in a similar range, wheelbase, at least as much as this can can be changed I did notice a difference. Even though the car will be shorter you think it would turn more but it puts more weight on the front so it actually turns less.

So you could say that moving the front end further forward on the chassis would be similar to moving the battery towards the back of the chassis, correct ?

makes sense. when i tried the short wheelbase i did not make any compensating change to the servo. i will try that next time for a better comparison.

that is the only rational explanation. so next time maybe i should try moving the battery back as well to get the shorter wheelbase with the same front/rear bias

although compared to the development version 12r5's at snowbirds. it seems like they are looking at even more fwd bias's.

Default TUBE CONVERSION

The S100 now has the tube conversion, any one have a set up for this car , tried it with the Markus set up and it was awful, changing the caster blocks to 6 degrees and cell forward every thing else so far is kit.Only changing one thing at a time.
Car was brill round corners but any str8 car was every where under acceleration.

Please tell me more. I went to Serpent website looking for tube conversion for S100 but could not find any info. Did you convert yourself or is there a conversion kit?

On-Point racing has the conversion. Stormer Hobbies carries it.
