22 diff. to balls it or gear it?

[TARTMAN]

I have been running my 22 for a couple months now and need to rebuild the diff.
I am wondering about the plus and negatives of the gear diff?

I have heard that there not great in the wet/slippy conditions compared to the ball diff.... Also, the rtr22 diff comes greeced and ready to fit i am told, but also people mention diff oil of various grades. Can someone explain what is best etc?

I have a spare 22, so am thinking maybe running one with gear diff for the dry and one with balls for the wet. hmmmm..

whats my options and what do you guys recommend?

I recomend ceramic balls

I haven't run the gear diff but can thoroughly recommend ceramic balls too.
They make the diff action so much smoother, which makes the car easier to drive and it lasts a longer between rebuilds too.

I believe the gear diff frees up the rear end a little which is why it works better on higher grip tracks. No doubt someone who has used one will comment soon.

Under the auspices of not starting another deadend thread, because it's already been widely discussed (everyone's tired of it, and the arguing), I'd suggest checking any one of the pre-existing threads where opinions have already been given......

here's a couple to get you started -

I stand by my comments in those threads,

Worth having one and trying it as it may suit the way you drive and improve the car for you.

Indoors on more grip predictable surfaces i would definitely run one.

5K-7K is the oil range i found to suit my driving best,

anything lighter than 5K and the inside wheel span up too quickly coming out of corners or the back end was twitching under hard acceleration

i did look but with so many thousands of threads, i gave up looking. this is a forum, opinions change often, and if a thread was a few months old, the opinions may have changed in that time and more people would have tried them.

If you dont like these new theads, best ignore them maybe?

one of those is not relevant and the other is 7 pages of babble. I am after a few simple replies to my question from those that have tried and tested both diffs...........

so back to my questions.......................

thank you so far, i have put it in the car and gona run as it came, with greece in it. then strip and clean it and try some heavy oil, thanks sounds like its worth a try....

The only problem with running with the RTR grease for racing (as they now come built...mine was a bag of bits!) is that you'll have no benchmark for tuning, any oil will be softer than the grease but give different resistance and temperature working tolerance...also a different feel to the car i would have thought... the grease in them is usually very thick and a pain to clean out going on experience with other Losi RTR gear diffs!

I started with 3K and went upwards, with each grade it improved.

Remember to bed it in before running it... hold one wheel and apply power, starting with low power and alternating holding each wheel.

I changed the oil in mine after a couple of runs to inspect it and there was some light swarf from bedding in, best to get rid rater than having increased wear rate on gears.

Just keep an eye on outdrive wear as they are softer than the ball diff outdrives

The car will instantly accelerate faster and brake a lot harder, it does feel completely different at first and you will have to adapt a little when taking jumps so take it steady to start with!

Hope it works for you matey,
