Really? I have the 47T for the Savage and it definitely has a 5mm shaft! Or do you mean the cast slipper hub? I have that too, although I bought it with the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFYP4&P=7]MT2 slipper set[/link] - ooooh wait I think that purple tube thing shown in the picture makes it up from 5mm to 6mm. I'm sorry about that! I should actually have looked on my Tornado instead of relying on my memory.
[link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFYP5&P=SM]here's the miscellaneous bits[/link] from the full set. Contains a 5x11 bushing, and the proper tube for the slipper hub.
Yeah, the slipper hub is 6mm, but that's OK, since I'll just use an old gear off the multi gear transmission. I do need to get the 11x5x4 bushing. I got to run it today and got the exact same speed as before. 37.7 mph. So essentially with the 49 tooth gear, I can run the same speed as the 44 but it has more low end. The low end is noticible and I was able to pop a wheelie and flip it backwards with a little help from the edge of the grass.
