slipper clutch on Tamiya Baldre

[Bigmuff]

Hello folks.

I recently got a Tamiya 53930 Super Stock TZ Motor and was intending on putting it in my mostly stock Baldre. However, I don't know if this 23 turn motor counts as a "high power modified" motor that as per the car's directions would require a slipper clutch. So now I'm afraid to install it for fear of nuking the diff.

Anyone know if I'll need the slipper for this motor?

Oh - and sorry if this is the wrong forum. I think my registration is bugged and I'm having a difficult time posting anywhere.
