Do the different degree caster blocks have any markings on them to know which is which?

Trying to figure out what's on the used 22s I bought and the spares. I can my plastic and aluminum 4mm trailing spindles are marked with 4s.

Hi All,

I'm familiar with electric 4WD RC but new to 2WD, so was wondering if you can advise on my Losi22 RTR? When I accelerate really hard the car seems to pull to the left quite suddenly, but only every so often, and also if I brake really hard the same thing happens, but also only every so often.

I have checked to ensure there is no binding on any of the wheels, that everything is aligned etc, and can't find a problem. The trim is also fine as well.

Could this possibly be due to the (RTR gear) diff action on a rough surface? I was reading from Casper's post earlier that ball diffs are preferred by 2WD racers as there is less chance of diffing out under power. So is this pulling to one side due to one side getting airborne/loose and then receiving all the drive, then when it contacts the ground again it drives that side forward, resulting in a change in the car's steering direction?

Is this a common 2WD experience, or should I be looking for some other problem?

Thanks!

Ball diff for the win dude.

Gear diffs are still good and minimal difference

wow, not intentionally I put my 22 through the ringer today. I raced a track I dont normally go to because of the difficulty and the fact I always break my buggy. Well I cleared the quad and landed on my shock towers a few times, hit the concrete wall with my front wheels a few times and landed crooked on the front wheels a few times at bad angles and never broke a single part. I dont even have any alum,m upgrades. The moto cross style layout gave me a few issues and the buggy really needed some steering and rear tracking, but at least I didnt break anything lol. With by b4, that would have been about $30 in parts. I am kinda impressed with the durability. Ir handled poorly, but durable as heck.

last two times out I had the diff screw break at the head. Both were the AE screw/diff nut set up. The first one was a year old, but last night's was two race days old. Any clues as to what might be causing this? Just bad luck? Buggy handled great and ran as good as ever. I did rebuild the entire diff the last time it broke including the thrust bearing.

I told you it was a tuff buggy.

Don't think it's odd that temp would't go up after the up in gearing?

20k seems very thick. I run on a medium bite track so what would you guys suggest? 10k?

Really puts into perspective how good you have to be to show up anywhere and do good huh?

Okay, here's the thing. There is a spot in gearing a brushless motor when a small change in gearing will not create any more heat. If a motor is under geared it will be slow and hot. Geared for the absolute best performance from a 17.5, you should be hitting 160° max. Over geared the motor won't make any more power than the right gearing, but it will make more heat. You are at the magical point where more gearing will mean more power and heat. Keep adding gearing until you come off the track at 155°. That being said, this goes for all sensored brushless motors, it has nothing to do with the 22, and really doesn't belong in the 22 thread. You will find the same final drive ratio would make the motor perform the same in any 2wd buggy. When I ran 17.5 in my 22, my Tekin Gen1 liked 35/69 for the larger track where I raced, and 33/69 at the smaller track. This was with no timing.

I feel like I post this info several times a year.

I have heard of guys running 1~2k on dirt with gear diffs.
