Anyone has a solution to the sloppy steering rack problem?
So far I've upgraded the servo horn.
the ball cup and ball stud part always have some play.
by tighten up the servo saver a bit, the right wheel feels okay, but the left wheel have at least 5 degrees of sloppiness. Just too much on that side.
the plastic steering rack, designed without a washer could be a reason. planning on upgrade the metal one later.
anything else I can do?

*it's mostly about confidence, I'm afraid of taking some aggressive lines because of it.

Mine has very little play at all, almost none. Are you sure the play is in the steering assembly, I blew a bearing and it seemed as if the the steering assembly was sloppy.

My son's steering has a lot of play, but it's still the best handling truck on the track. It's been sloppy since we built it 2 months ago. Since then he has averaged at least a battery a day through it and it has not gotten any worse. I would not let it bother you too much. Here's a video of his race last weekend, his TS4 is the red and yellow truck, the rest of the field is losi and ae, and he puts them all a lap down. The loose steering does not hurt the handling at all.

found the problem,
Horizontally, The screw's non-threaded part is 3.45mm in diameter, but the hole in steering rack is 3.59mm.
Vertically, the non-threaded part is around almost 1mm longer than the thickness of the steering rack.
I "over-tighten" the screw a bit, tight enough to remove most of the vertical play, but loose enough to keep it smooth. Seems help a lot.

although, the sloppiness in the suspension arm mount still exists. it's 3mm pin inside 3.3mm hole.
most of the cars I have, onroad and offroad, require M3 reamer to loosen up a bit, this one seems is a bit over-concerned. :P

great driving.
most of the time the sloppiness won't do anything. the caster will keep the car go straight anyways.
it's the little correction you want to do when accelerating hard on the straight scares me, especially on a tight track, once the correction was delayed, it may ends up with a nasty crash.

Depends on your track conditions but the 5 holes seem to be the best all around unless you are on a blown out track then the 6 hole would be better. I would drill out the rear to 1.2/1.3 and leave the front at 1.1/1.2 and use 325/275 for your starting oils.

Thanks.

Slash rears work too.

OK so even though the truck scales around 51/49 it just seems to drive front heavy. I havent been able to really get the rear to stick on exit as much as i want to and it has a tendency to nose down on most jumps so you have to keep light throttle while in the air. The DESC drove the same way and the dual shorty mod along with stiffer rear springs fixed it. So yesterday while i was drawing up a plate for a dual shorties to fit on the TS4 I decided to weigh the difference between a normal stick pack and two Shorties and it is about 80g. I really didnt want to go to that extreme with the truck and wanted to keep it with the stock layout if at all possible so i decided to test with just adding 84g in the rear close to the center.

This along with lowering the roll center:

The combination ( I was also testing new piston designs) completely planted the rear and allowed me to really put the power down without fear of the back stepping out too much......FINALLY! AND it jumps much better, nose stays up like its suppose to! I think it may be better with a stiffer spring as i am still using the 22t yellows, I will play with springs tomorrow and maybe get some vid!

A little teaser on the pistons: front was 4 hole 1.5mm/300cst rear 5 hole 1.5mm 250CST front felt pretty good rear needs either bigger holes or more of them.....more later!

Here's his setup sheet. We are running a saddle pack battery (http://www.rctech.net/forum/electric...l#post11034175). Right now there is still a ball diff in the front also, I just haven't had any reason to pull it out and put the rebuilt gear diff in the truck, and he seems to like the handling better with the ball diff. My son is only 10, but he can drive a toy car pretty good. His biggest problem is seeing through everybodies radios on the stand.

I picked up a slightly used TS4 and have a Reedy Sonic 550 4.5 to install where should I start the gearing on it?

What is the trans ratio?

Where can I get a manual? I did not see one on Team C website to download.
