As for the hubs, the HPI are fine, use the outer hole as Spashett recommends. You can also use the rear HPI hubs if you don't want to buy the aluminium ones, they are 0 and fit if you re-drill the hinge pin hole. They'll give a more angled turnbuckle so you'll have to shim it more on the chassis side, and the locations for the turnbuckle are a bit different too, but it's fine, plus you'll have longer lasting bearings.

Regarding the slop, it may seem bad but the car just works, it's not excessive and anyway the amount of parts twisting under effort is more important than the slop.

yes, MSX... yes, it is flexible even w 3mm chassis.

Hopefully Tamiya releases this 4mm chassis.. and perhaps a 3mm top plate pkg..

I don't know what carpet it is, it's medium to high grip and we use sorex 24, this is for 19T. You can use one of the interactive sheets i made for TryHard, they're available on his website.

Is there another spindle carrier that will work on this car for foam tires? I ask because the akerman with the locations on this block VS the rack seems weird. Id almost like to add an extension to the block.

try this the standard hubs w/ the old press on 6mm hexes (silver) and .5mm of shims. puts it dead on 190mm

Default updates

hey all.

I've just updated the Universal spring chart on my site, turns out my supicisions were right, some of the values for the tamiya springs were off. This has now been corrected, with thanks to TRF415Boy.
Also made it easier to read off the values.

Also, I've updated the gearing chart to the latest one I use, with more values for the 19t gearing range (ie, near the 5's for the fdr)

Also, had my first run outdoors with the MSX this weekend, car was great, handled exceptionally well. Given that the ashby track has got seriously bumpy, I'm very with how stable the car felt. Anyway managed my best result of the season, Q'd 9th in the A, with an 8th and 7th in the two finals (placed 10th O/a). Very happy, and deffiently feel the car is an improvement over the old one.

Regards
Ed

I knew that was a tall order what do u think about just the DJmod rubber on crc carpet is it better for out doors... and wow there is a bit more flex with the msx but Ill bet a new top deck will help ..I wonder how long before they come out with a new top deck with side post holes or do I make my own looks like it will be easy................

Default 415

Rod, Keith, Customworksking, TRF415boy,

For what it's worth I did a lot of testing with the dj suspension and found that it produces a much more stable car turning into the corner but seems to loose corner speed mid corner compared to the lw or original 415 suspension. When I drove the dj suspension at the tamiya america track I could run more consistent lap times, but when I tested it on carpet back home, my lap times where a couple of tenths quicker with the lw suspension over the dj suspension.

Yes the msx does have more flex than the ms which has more flex than the original 415. The original 415 had virtually no flex and is likely best suited for foam carpet racing unless Tamiya does produce the 4mm lower deck. I did the old tweek test on Marc's foam 4mm chassis in vegas and this car was rock solid. To stiffen my MSX I also used the 3mm chassis from the original 415 which helps. The allum uprights make a big difference in the rear slop. I also found the HPI knuckles reduced the front camber slop, but does not reduce the steering slop that comes with any ball cup linkage system. If you don't want the 2 degree caster option then I would just us the original 415 suspension as it has less slop than the lw suspension due to the larger bearings. I am using the lw suspension because I want the 2 degree caster option if I need to reduce mid corner steering.

I ran the car at my local track this past weekend doing some foam tire testing and the car was awesome. It was so easy to drive. Now the grip level was just average at this track as it does not have the benefit of 75,000 laps in a few days like vegas, but so far so good.

Here is my foam setup so far....For cleveland I expect the only changes I will make are to go up one level on the springs all around and go up one level on the front swaybar to blue. I experimented a lot with the roll center this weekend and found the high front roll center and the low rear roll center made the car handle the best...very smooth, compared to a lower front roll center.

Tires : Speedmind multi on the front and 35 shore on the rear. I little more steering than the parma cyan, magenta combo or jaco double pink/orange , double pink combo.

Front:

droop - 1.5mm
springs - associate copper ( likely use purple at cleveland)
oil -60 orion
shock Pos. - three holes in on shock tower. inner of three holes on arm
inside upper links - 5 mm of spacers
ackerman - rear holes on hpi knuckles, swept back bell crank
blocks - d and d no spacers
caster - 4 degrees
sway bars - yellow (likely use blue in cleveland)
toe out - none
wheel hub spacers - 1mm
belt - position -1
lw suspension
camber -1.5
wheel base - 6mm forward (using the original 415 chassis w/ lw susp.)

Rear:

droop - 1mm
springs - associated red
oil - 60 orion
shock pos - two holes in on shock tower, inner of three holes on arm
inside upper links - no spacers
outside upper link - 0.7
upper link length - middle hole on upright
blocks - d and b, no spacers under the blocks
upright - 1 degree allum (total 2.0 toe in)
wheel base - 6mm backward (using the original 415 chassis w/ lw susp.)
belt - position 0
ride height - 5
lw suspension
camber 1.5

i just bought the x ray strap for mine, i had to screw in one hole and its awsome, first time iv used the car with now battery issues!!! well worth the $30 for the strap kit, high quality piece... you can get out cheaper simply buying a couple of posts and an associated strap, but remember you get what you pay for!!!
