Doc, Thanks for the suggestions.
I think you need cvd universals to eliminate chattering during hard cornering. Also reduce steering throw from your remote.

Slotmachine,

I removed one "O" ring from inside both of the rear shocks and that substantially reduced the chatter. It made the car steer more crisply and it didn't scrub speed through the corners like before. I went from a 4th or 5th place car to a car that could challenge for the lead.

Thanks for the help

The TA03 diff is nicer IMO. It's much smoother.

It also has a narrower gear, which is a big plus when you have a very limited motor. Less friction and less weight.

I`m glad I could help out, try removing 1 o-ring from the front and see if that helps out more.
Paul................

By the way, how was the traction roll issue with 1 less o-ring?

Paul,

Traction roll was not a problem at all. I don't think the car sits any higher, than before, with one less "O" ring limiting the shock travel it can just lean over just a little more.

I will try it with one less "O" ring in the front shocks next week and let you know how that works.

Thanks Again

Since the mini coopers are less sophisticated and don't have droop adjustments you have to adjust it with the shock length. Since you put more droop in the rear I was hoping that there would be no traction roll issues. The reason being is that you slowed the reaction of weight transfer down so it worked like I wanted it to.

Talking TAO3 BALL DIFF

I am in the process of re-building my TAO3 Ball diff in my MO3L and insteead of placing the thrust bearing I am going to place a 1050 wheel bearing and a washer under the hexagonal bolt. I believe this will give more option of running the diff tighter. The only problem I can see with this, is it will more than likely push more coming out of corners.

Does anyone have a opinion on this, as I was also considering building the bevel gearbox with additional washers on both sides of the bevel gear for a tighter fit. This should get the diff to act similar to a spool, which will I think cause additional push through corners.

I am trying to build a diff which will allow faster cornering speeds, while maintaining good handling.

I only run my Mini on asphalt tracks with 60 D tyres. Thanks for you info previously slotmachine.

Any assistance appreciated.

I build my TA03 ball diff like it says in the book, stock grease. I use lock-tite on the adjustment nut. I tighten the bolt very tight and then back it off 1/8th. of a turn, kinda works like a spool also. I have no on power push at all. With mini`s you just have to let off early and hit the throttle at the middle of the apex to carry corner speed.

Talking MO3 DiFFS

Well I have rebuilt the Mini with the TAO3 ball diff setup tight and loctited the Hex nut. I have not greased the diff running surfaces, ie pinion mating areas. I fitted a F201 flourine coated 20 tooth pinion onto a Fantom 27 turn stock motor. I ran this up the road and this certainly moves along. I don't think my 1400 batteries will last 5 min runtime though.

We are running super cooper on Mon night at our RC club prior to Xmas break. Will take slotmachines and oldnwise advice and try to slow in and fast out the corners and see how I go.

Thanks for the advice.
Calvin.

I also got a motor from doc and i was up two more laps a race this week compared to last week. And it is still just a two hole motor.

If your out there Doc thanks again. I almost gave up on my mini.
