Quick question. Will the Tamiya ball diff for the M05 fit the M03?

Thanks.

ErikO,

I hate to disappoint you, however the new MO5 diff will not fit the MO3. The MO5 has 1510 bearing mounts injected into the chassis the MO3 has only 1150.

Regards,

Calvin.

OK guys, now that it's been out for a while, what's the verdict on the M05? Better than the M03 or just different? I'm sticking to my M03 for the time being.

Starting to like mine a whole lot better. The steering links are a weak point, but the 3Racing steering links work very well. Mine is very easy to drive and is very quick even with me driving. Right now there is very little difference between my 03 and 05. Took a little work tho.

I'm going thru a lot of gears. I've noticed that the new gear sets are a different color than the old ones. The gears in my M03 have been in the car for close to a year, but I'm on my third set in the M05. I'm fairly certain that it's not inherent in the 05, but I'm beginning to suspect the new gear sets.

I am very happy with the MO5 and I agree with Granpa that the new gear sets are not the same quality as the old sets. I am also using the 3Racing steering set on my MO5M aand using the plastic on my MO5L. I do have the Tamiya steering set coming as well as the Tamiya MO5 Ball diff. I hope its as good as the 3Racing offering.

I did some testing today and have this to report. The same report is on the MO3/MO5 Thread in the Aussie section.

Well I have been procrastinating about giving this diff a try and after Friday nights effort at Windsor, decided that I would fit this to my MO5M.

The first thing I did was to strip it down. I checked all of the parts. I sanded the diff rings so they were nice and smooth, cleaned the clear diff grease off the rest of the parts and re-greased the thrust bearing. During the rebuild I used AW grease. When finished I put the assembly in my car and tightened it in the car. The black blades were then fitted to the universals and I was under way.

I set the diff as tight as I could get it and then went to Whalan to test the car out. I started with the usual tyre combination and only ran 3/4 pace for about 5/6 laps just to see what handling difference would occur. I suddenly had more steering than I needed, so I adjusted my steering speed and I also checked the diff to see if the diff had loosened up, which it hadn't.

I then set about using full throttle and concentrating on my lines. In no time the pack was gone and the car was so much easier to drive. With the ball diff the car tracked straight with no wander and went into the corners tighter, not the push I was getting from a really tight ball diff. It was so good I stayed and proceeded until pack no 2 was gone. The great part is the blades showed no sign of letting go and the diff is the same tension as when I started.

To say I am impressed with the 3Racing MO5 Ball diff is an understatement. I am now looking forward to comparing it to Tamiya's new ball diff this week. I am also glad to see the problems I was having with the car with the old diff have gone a way.

Now to just try it under race conditions.

Later,

Calvin.

I think on a more techinical, tight track the M05 is much better. The M05 just seems to have more mid corner steering over the M03. On the more flowing tracks i have noticed there isnt much difference between the m03 and m05.

Thanks for the reply Calvin,

I have an old TA01 ball diff that I may try out, the only issue that I've found is that the outdrives fell out when I drove the car. I'm not sure whether to put the ones from the gear diff in the ball diff or whether I need to get other ones. I'd like to make it work if possible.

What's the difference from the M03 & M05?

Thanks

the biggest difference is the position of the steering servo. Google some pics.

I found this very interesting;

studysession, main difference is the front suspension of M05 is much harder than the M03. The M05 to me corners better and is easier to drive than an M03. The M05 is also less succeptible to traction roll compared to an M03.

Do you mean like completely roll over?

Studysession:

the M05 has a lower centre of gravity, so it is less prone to traction-rolling, which is when the lean of the car causes it to flip over in a turn. It gets the lower CG by mounting the steering servo mounted in the back of the car, instead of on top of the gearbox/chassis like the M03. This also moves the weight further back in the car, giving it better balance and reducing the likelyhood of traction rolling even further.

Other than that, it is very similar to the M03. The suspension, gearbox and wheels/tires are practically identical.
