I saw that the LM has it's own ball differential.

Why is this?

I presume I can't use my kyosho ball diff for MR02 then?

Cheers,
Tom.

The shaft on the LM is 5mm longer. You could probably just get a longer shaft if those are available.

You could still use the MR-02 diff but you would have to adjust the wheels that you use based on your body choice.

Note I talked to Philip (PN) the other day and asked about this. He said that this is not necessary when running his new laydown motorpod. The standard diff will work. This new diff is only required when running the K plastic motor pod and ya want a ball diff.

The standard diff will work but you the wheels will be well inside the body if you are using a LM car like the 962 or 787. I had to use plastic spacers on both sides of the PN motor pod for the LM diff to work and fill out the wheel wells.

If your going to use the PN motor mount you will need the 3 degree offset wheels for correct stock wheel width.

You could upgrade a ball diff with a longer shaft:
#MZW302-01 SHAFT (LM Type/for Ball Diff)

I used an F-1 ball diff for my Porshe body with the K plastic motor pod, it is a little short but it does the trick.

wondering if using the f1 shaft with the mr02 ball diff parts will do the trick....

It does sound like a good idea...

Pfcparts has done this before for an MR02 Enzo. The F1 shaft effectively adds 3mm of offset, so it's a viable option. :)

Ihave tried it with MR02 parts, it works however the F-1 parts don't work with the MR02 diff. Initially I was running the stock MR02 spur gear from my Kyosho diff. Currently I am running the F-1 spur with an 8 tooth pinion. The spur just barely clears the track surface.

hmm.... do you mean you've tried the f1 shaft with mr02 parts (and it works with the lm?), however the f-1 parts don't work with the mr02 shaft?

The spur just barely clears the track surface.
hmm... if i remember it right, the f1 spur is 45t....mr02 spur is 44t... and mr01 is 42t.... hope someone could clarify/confirm this... :D

so i think anything smaller than the f1 spur would work...

thanks for the info... :D

Did that today relatively inexpensive and easy conversion.
