The above article came off HPI web site and says it will work. I HAVE A MT2 SLIPPER CLUTCH SET UP IN MY MT1 SO I KNOW IT WILL WORK. Sorry for yelling but I know it will work as I have been running one for well over a year in mine. Matter of fact more like 2 years. If yours did not come with a slipper it is a RTR. The old MT 1 slipper is junk and does not work well.
This is what I have in mine!

I use the same spur gears in my MT as I do my Savage.
