keithander, yeah man, you're right. the si is such a nice car. i'm not sure why it never took off. the type t seems the most popular, and like you said, even that information is scarce.

robk, i'm foolishly counting the days. i can honestly say, i can find nothing wrong with it. it is a near manifestation of my thoughts. the diffs look heavy, but a losi 41t should swap out if we up the layshaft from 21 to 22 teeth to make up for the difference. that's based on the assumption that the pullies have not changed from the assassin. sure, i'm mildly sick.

Hey seaball....

The si is working well for me but I have found a few flaws now... The upper deck is easy to break with a good hit (I have trashed 2 now) and the diff rings slip against the outdrives. CVD's wear quick too.

Apart from that it has been fast and I have already had a good victory (mod) against drivers of calibre (here in oz anyway). The best change I made was using the front suspension mount on the rear! Better overall grip with 30wt oil and shocks mounted inboard.

I too am looking at the new corally, simply because I would like identical f/r suspension geometry and better quality in the components (MIP CVD's with blades will be great!) Just trying to find a decent adjustable shock to use on it (No evil x-ray parts on my cars). Anyone know parts numbers for the serpent adjustable shocks?

Dragonfire, the xray shocks are an evolution of the serpent shocks, and are much better. the only other adjustable shock i know if is the CRC ones, i believe they are made for the TC3 but should fit any tourer, no idea on pricing etc

i've got a set of serpent shocks i'll sell for cheap off of a corally c4.1. infact, i'll sell the whole car for almost nothing.

lmk.

it's good to hear of your success with the atlas car. i have not put my si on the track. i never found a diff for the front of it.

and yes, the identical geometry is an attractive attribute of the corally. it will be an awesome car, but the diffs look heavy. i know the assassin ones were, and these look the same.

After assembling the diff, putting glue on the *** back side *** of the diff rings where they meet the outdrive can help to prevent slip. This is by no means a perfect fix, but you can give it a try.

The Atlas cars have both great ideas and huge annoyances. I wish that I spoke Japanese so I could write scathing letters of praise and fury........

I did glue the diff rings to the outdrives (delrin) and I roughed up both before hand. It held very well for a while but to test my diffs, I try to rotate one wheel while locking the other and the spur. This caused the glue to fail if I pushed it a bit hard... but I can't avoid it as the diff has to be set right....

The diffs would be better if they had a flat edge somewhere on the inside of the rings so they couldn't slip.

Hi brad: sorry but I will always maintain an x-ray free zone in my garage.... Just trying to find a modern adj shock so I can get spares/replacements when required. Will look into the crc ones tho.... thanx...

Another idea might be trying to "pin" the diffs. this involves driling a small hole into the outdrive so a small rod can be inserted into the outdrive . The thing is the diff rings need to be notched so the end of the rod will keep them from rotating. That's the hard part.
A lot of 1/10 pan cars used to use this.

Default New Atlas - YM34 type Si II

Seems to be a new Atlas on its way!

From what I can make out it looks like a lot of new parts compared to the old Si version - new bulkheads, new 3 piece top deck, new battery mounts/bar etc. The motor also seems to be mounted further forward.

Anyone know anything else about the car? Is there a front normal diff available? Release date?

There's a download to the instruction manual here....

looks like the top deck has a separate part over each of the bulkheads.
